Pentium duo core with 2 GHz or above, 1 GB RAM or more, > 2GB RAM with Vista®

Graphics card supporting OpenGL

The disk space required on your hard disk can vary depending on the

Installation type selected.

1.2 Installation of the program and the luminaire catalogue off a DVD

Please close all other programs before installing the program. Place the DVD in your DVD drive. The setup for ReluxSuite ought to start automatically.

If the setup routine does not start, this probably means that the „Autostart“ function has been deactivated. You should open Windows Explorer, select the drive in which the Relux DVD is located and start the setup manually by double-clicking on the start.exe file.

The installation program starts with the opening screen for selecting the language. The language selected here applies for the installation only. Different languages can be selected later on when using the program and also for the program outputs. You start the installation of the main program by pressing on ReluxSuite (Fig. 1).

Fig. 1

Note: If the 2007 Version is already installed on your system, enter a new path for the ReluxSuite Version. If you need your projects from Relux Professional 2007 and the imported LDC’s at a later date, you can copy these into the ReluxSuite directory.

You should now select Install ReluxSuite. You should now read the licence agreement and accept it so that you can continue with the installation (Fig. 2). Select the coun-try in which you are located. In the next window, you can specify a path for the in-stallation of ReluxPro. The default proposed for Relux is C:\Program Files.

INSTALLATION 5/81


Fig. 2

Once the setup routine has copied the program data, you can specify the language for the user interface, the outputs and the database. You can change these set-tings in the program at any time (Extras – Language).

You can choose whether you install the manufacturer data locally (this is recom-mended if you have sufficient memory space, duration approx. 20 minutes) or whether you wish to use this data off the DVD. In the case of a network, we recom-mend copying the data to a network drive, so that all users can access it. You can se-lect the manufacturers by double-clicking the tick or by using +++ or ---. If necessary please refer the Relux Professional 2007 manual for a more detailed description of the installation process.

PART 1: GET STARTED IN 5 MINUTES 11/81


3 PART 1: GET STARTED IN 5 MINUTES The following 4 features will help all advanced Relux users to switch in the new Relux-Suite. Enjoy a new look and feel: the user interface with the main menus has been revised. For your convenience it is clearly structured and much more user-friendly. Beside this first approach to ReluxSuite 2010 the interested Relux user will find all information around Relux Suite 2010 in the second part of this manual.

Note: please refer part 2 of this guide for a more detailed description of this features.

3.1 New look and feel: the revised user interface

General: The interface can be changed interactively. The software will be delivered in the “Standard layout“ and can be enhanced to achieve the complete user interface layout under “Window - Extended layout” (Fig. 8).

Fig. 8

3.2 The logic governing the rotating and shifting of objects has been changed

Move or rotate objects in a new way General: moving and rotating objects works con-sistently in the same way in both the floor plan and the 3D view. These commands have been refined for the movement or rotation of objects in the 3D view as of Relux-Pro 2006.

1. Just click to an object in your current scene to select it.

2. The coordinate system appears (Fig. 9).



3. As soon as the mouse pointer approaches the coordinate system (the x, y and z-axis (z-axis only in 3D view) as well as the square areas between the axes), its initial color changes to yellow.

4. Click once with the left mouse button (Fig. 10).

The color of the handle will change from yellow to orange and you can move the ob-ject around without keeping the left mouse button pressed (Fig. 11).

5. Press „Esc“ to leave this command

3.3 Import and Export dwg or dxf formatted files

General: The new powerful CAD interface allows to import all dwg, or dxf files within a few steps. Just start ReluxPro and try the assistant CAD import. Follow the 7 steps to import a CAD file:

step 1: enter project data

step 2: select a file (dwg, or dxf)

step 3: define layers to be turned on, or off

step 4: define drawing units (usual 1000/m for interior projects and 1/m exterior pro-jects)

step 5: set rotation (requires knowledge of the drawing, otherwise proceed to step 6)

step 6: set origin (requires knowledge of the drawing, otherwise proceed to step 7)

step 7: draw scene (interior, or exterior)



Fig. 12

To Export a Scene from your current project as dwg-, or dxf-file select “File – Ex-port - Scene as DWG/ DXF…”.

3.4 Edit and draw objects in the 3D view

General: towards the previous versions all edit functionalities can be performed in 2D and 3D view mode. This allows for e.g. the move, draw and scale of objects that are located on a wall like doors, windows and figures (Fig. 13)..

Fig. 13 move Room element in the 3D view



3.5 ReluxEnergy

ReluxEnergy is the powerful free of charge module to calculate the energy consump-tion for interior lighting of non residential buildings. It refers to energy standards and norms as EN 15193, DIN 18599-4, (SIA380/4 & CTE HE-3, May 09).

Fig. 14 excerpt from a German energy pass

3.6 ReluxTunnel

The tunnel calculation software has been developed for experts and refers to norms CIE88, CIE140 and SLG201 (Fig. 15+ Fig. 16). You must purchase a license to run this module. For further information please contact us via e-mail at [email protected], or by telephone on +41613330770.

3.7 New ReluxMovie module

Fig. 17 Animation module

By incorporating several camera positions in the 3D View, the program subsequently generates a camera flight through the scene. Use the 3D View to set the individual camera positions.

The following steps are necessary for generating a film:

Step 1: Select Add new animation from the “Animation” toolbar.

Step 2: Select the speed at which the camera should move.

Step 3: Enter the first position in the 3D view. Select Set first camera posi-tion.

Step 4: Repeat Step 3 for each additional camera position.

Step 5: To check: play the animation with Play animation forwards.

Step 6: You can change the route for the animation in the 3D view. To do this, click the mouse on the camera position (blue square) and change the posi-tion.

Step 7: Render animation



Step 8: Select format, resolution and codec

Step 9: Select file name and location for saving file

When an animation is set up, a time axis appears at the bottom of the picture show-ing each individual camera position with a triangle and a line.

The duration of a new animation is 30 seconds on the basic setting. This can be changed in the properties for the animation.

Fig. 18 Animation bar

If the time axis controller is moved with the Shift key pressed, the preview in Fig. 18 will be played manually.

A camera position selected on the time axis (the position is given a red marking) can be shifted along the time axis by moving the controller while keeping the Ctrl key pressed. If the Ctrl key and Shift key are pressed simultaneously, the marked camera position and all those after it will be moved along the time axis.

The functions of the different pictures are set out in the following table.

Set up an animation

Render an animation

Set a camera position

Delete a camera position

Jump to previous camera position Ctrl + Alt +

Jump to previous picture Ctrl + Shift +

Play animation backwards Ctrl +

Stop animation Ctrl + or Ctrl +

Play animation forwards Ctrl +

Jump to next picture Ctrl + Shift +

Jump to next camera position Ctrl + Alt +



Useful key shortcuts:

To ensure that the observer height can be maintained when the different camera posi-tions are set, a useful key shortcut has been introduced for operation via the mouse and the keyboard. As long as you keep the Alt key pressed, the observer height will be maintained.

Maintain the observer height when moving and rotating in the 3D view. Alt

Note:

It is not possible to continue with a rendering process that has been interrupted.

The film is not saved in the Relux project file but in a separate file.

Uncalculated and calculated scenes can be rendered by the radiosity method. Raytrac-ing scenes are not taken into account.



3.8 New, GR and TI glare rating outdoors

The glare rating in outdoor projects has been extended in the calculation manager. Under the Artificial light calculation, and the Glare rating tab, it is now possible to calculate new GR and TI values for several observers.

Fig. 19 Calculation manager dialog

In addition to the determination of GR values for sports grounds, the glare can also be calculated for other outdoor applications.

It is possible to define individual observer points or groups.

Fig. 20 3D View of an outdoor project Fig. 21 GR Observer points



In addition, there are ready-prepared observer grids for the calculation of the GR and TI values. The first grid was compiled for passengers on the platform and the train conductor in accordance with the guidelines applied by the German Railway (DB).

Fig. 22 3D View of the platform Fig. 23 GR values for the observer points

for railway passengers and TI values for the observer points for the train conduc-tor.

Note: The surrounding luminances used for the calculation of GR and TI are estab-lished by the approximation method described in CIE 112. Contrary to the ReluxStreet module where the luminance is established from directed reflections (r-tables), diffuse reflection is assumed for general outdoor projects.

PART 2: ENHANCED FEATURES FOR ADVANCED USERS 22/81


4 PART 2: ENHANCED FEATURES FOR ADVANCED USERS

4.1 Move or rotate objects in a new way

General: moving and rotating objects works consistently in the same way in both the floor plan and the 3D view. These commands have been refined for the movement or rotation of objects in the 3D view as of ReluxPro 2006.

Fig. 24: shows a selected cube in a scene

Fig. 25 selected cube with activated handle

Fig. 26 cube with the active handle moved 0.5 m in z-direction. Basic operation “move” and “rotate” in the toolbar.

Just click to an object in your current scene to select it (Fig. 24).



As soon as the mouse pointer approaches the coordinate system (the x, y and z-axis as well as the square areas between the axes), its initial color changes to yellow. (Fig. 25).

The color of the handle will change from yellow to orange and you can move the ob-ject around without keeping the left mouse button pressed (Fig. 26).

Press „Esc“ to leave this command.

The advantages are follows:

The movements of objects are more convenient without keeping the left mouse button pressed.

During this movement operation of objects it is possible to change settings such as the placing grid, etc.

An operation can started in one window (e.g. floor plan) and it can be finished in an-other window (e.g. 3D view).

The viewpoint can be changed during this operation (you can rotate, pan and zoom

the view).

Move, rotate and scale are the most important operations for constructing a scene. You will find them in the menu bar under “Tools

Fig. 27“ and in the toolbar. They all have

special handles and a specific mouse pointer which you can see in . From left to right: move object, rotate object, scale object.

Fig. 27 handles and cursors for some operations (photomontage). From left to right: move object, rotate object, scale object.



4.2 Move and rotate working plane

The working plane can be moved and rotated like any other object in the scene. You can start these operations with the menu Tools - working plane. From here, choose either move or rotate

Fig. 28. The handles, which you see afterwards, belong to the working

plane ( - Fig. 30).

Fig. 28 original position

Fig. 29 new position

Fig. 30 after rotation



4.3 Edit and draw objects in the 3D view

The rotated working plane can now be used for drawing an object for instance a stair-case. After setting an appropriate placing grid - use the ”raster properties“ icon - start with the design of a staircase using the command “draw a cube with the mouse“.

Fig. 31 draw object in 3D view

Each mouse click on your working plane creates a new point. After you have defined the last point, terminate with “return” or double click the last point. To exit the edit mode, press “ESC“.

Note: during the “draw cube with the mouse“ command, you can undo wrong entries with “backspace”. Enter your input with “return” or double-click the last point.



4.4 Align objects to external walls

Move an object onto an rectangular wall and see how the object turns among its lengthwise axis so that it is always parallel to the wall (Fig. 32).

Fig. 32 Align objects to external walls

If you want to repeat this command, please select the object and after you have moved the mouse pointer to the small black cube of the coordinate system its initial color changes to yellow. Keep the left mouse button pressed and align the object to an external wall of your choice (Fig. 33 - Fig. 35).

Fig. 33 Selected object

Fig. 34 click the black cube: its initial color changes to yellow.



Fig. 35 Keep the left mouse button pressed and align the object

Whether the object turns the right way or not will depend on where the origin point and the object axis of the object are defined. Click on the object, press the right mouse button and select “Use object axis”. If the zero point is on the rear side and the Y-axis is parallel to that part of the object, as it should be, then there will be no problem.

Fig. 36 object axis related to the scene

Fig. 37 press the right mouse button

Fig. 38 and select “Use object axis”



Note: The automatic object rotation works for all objects in 2D and 3D. You can move objects along rectangular external walls using the object axis.

4.5 Modification of insertion points

From now on it is very convenient to change the insert point of 3D objects. Therefore select an object (except manufacturer’s 3D luminaires, or 3D furniture), open the context menu via right mouse click and select the option “edit insertion point”. Another option is to select the same command from the fly out menu “Tools”.

Fig. 39 select the object of your choice and click the right mouse button

4.6 Multiple insert function

If you want to insert an object into your scene from the objects and control panel you have two options:

Use the drag and drop function to insert an object from the objects and control panel into your scene as usual (since Version 2006-1).

Click once on the object of your choice in the objects and control panel. Now you’ve entered the multiple insert function mode. You can click onto the 3D view as well as the floor plan as often as you wish to insert the object. Exit this command with “ESC”.



Fig. 40 “objects and control panel” and multiple insert function mode

4.7 Placing grid/ raster snap

There are two different snap functionalities. The first is for a typical Relux scene, and the second for imported CAD drawings. Here we will consider the typical Relux scene (for CAD snap mode please see capture „CAD Import“).

The icons in the toolbar are:

switch the view of the snap grid on and off.

snap onto the crossing points (standard).

raster properties: change the grid size, snap into the center, etc.

snap into the center (you’ll find it in the menu raster properties).

The center snap option in the menu raster properties is very helpful for recessed mounted luminaires in particular ceiling systems. You can use the above-mentioned icon for this. To change for instance the grid size, open “Raster properties” menu.



Fig. 41

4.8 Move and scale room elements

Zentriertes Zeichenraster im Grundriss

From now on room elements, such as windows, doors and Fig.s, can be selected di-rectly on the wall and moved afterwards (Fig. 42).

Fig. 42

Their size can be changed as well (Fig. 43).

Fig. 43

To change a dimension, click on the red point and move the mouse. To move the wall element, use an axis (X, or Y) or the square area between the X- and Y-axes, like all Relux Objects.



If you would like to move the wall element from one wall to another wall, click on the black cube and press the left mouse button while moving it.

4.9 Draw polygonal scenes (interior, exterior)

Define a new interior project, or add a new room to the your project. Choose a po-lygonal room shape (Fig. 44).

After that dialog, you will be in the 2D edit mode, where you can define the room shape and the length of each wall (Fig. 45).

You can end this 2D edit mode with a double click either or the „ENTER“ key. A new menu opens and you can extrude your scene either to the Z-, or X-Axis (Fig. 46).

This procedure works also for exterior projects (without extrusion of the walls)

Diese Möglichkeit erlaubt es sowohl Räume aus einem Grundriss heraus, wie auch aus einem Schnitt zu konstruieren. Dieser Vorgang funktioniert sowohl für Innenräume als auch für Außenprojekte (dort entfällt das Extrudieren der Wände).

Example 1: extrude scene to Z-axis

Fig. 44 selection of room type



Fig. 45 2D edit mode

Fig. 46 set direction of extrusion

(Fig. 44- Fig. 46) If you want to add or remove corner points, select the scene and find command “Corner point insert” in the fly out menu under “Tools

Fig. 47“, or in the fol-

lowing toolbar .

Fig. 47

Fig. 48: from left to right: Click on corner point to move it, click on the blue line be-tween two corner points to add new point.

Note: During the drawing command, you can change the snap grids or use zoom functionalities. The backspace key will remove the last corner point.

Example 2: extrude scene to X-axis Define a new interior project, or add a new room to the your project. Choose a po-lygonal room shape. After that dialog, you will be in the 2D edit mode, where you can define the sectional room shape and the height of each wall. You can end this 2D edit mode with a double click either or the „ENTER“ key. A new menu opens and you can extrude your scene either to the X-Axis.

4.10 CAD import with ReluxPro

There are two ways to import CAD files. Option one is to construct a CAD scene from a CAD plan. The second option is to import CAD drawings into existing scenes, see File-Import-CAD Plan.

Example 1: construct scene from CAD plan)

Fig. 54 CAD import

General: The new powerful CAD interface allows to import all dwg, or dxf files within a few steps. Just start ReluxPro and try the assistant CAD import. Follow the 7 steps to import a CAD file:

step 1: enter project data

step 2: select a file (dwg, or dxf)

step 3: define layers to be turned on, or off

step 4: define drawing units (usual 1000/m for interior projects and 1/m exterior pro-jects)

step 4: set rotation (requires knowledge of the drawing, otherwise proceed to step 6)

step 5: set origin (requires knowledge of the drawing, otherwise proceed to step 7)

step 7: draw scene (interior, or exterior)



Fig. 55 select CAD file: dwg, oder dxf

Fig. 56 switch on or off the CAD layers

Fig. 57 set position



Fig. 58 set drawing unites

Fig. 59 rotate drawing

Note: In the ReluxSuite program directory (..\Program Files\ReluxSuite\examples) you will find some example CAD drawings.

After step 5 you will reach the “Floor Plan” where you can select all corner points of your scene. For efficient use we suggest to use the CAD snap mode (please refer to tool bar CAD snap mode(Fig. 60).

Fig. 60: CAD snap mode



Fig. 61 draw scene (interior)


Fig. 63 set scene type



With a double click on your scene you will open a new menu, where you can set the type of your scene (interior, or exterior) as well as the direction of extrusion in the following menu (Fig. 63). After this step the scene is completed.

Fig. 64 3D View

There are icons and a dialog box for working with CAD drawings:

Icon for the “Properties” dialog.

Icon for switching on/off the snap mode for CAD drawings. Tool bar CAD snap mode (below).

Icon turns drawing on or off, like a layer “Show CAD plan”.

Fig. 65 CAD icons and tool bar “CAD snap mode”



Fig. 66 Plan properties

Note: If you wish to, you can add additional scenes to your imported CAD drawing with a click on the button „draw scene“ (tool bar “Tools”).



Example 2: add a second CAD drawing to your scene A scene in your Relux Project can contain more than one CAD drawing: for example a floor plan and a section. Therefore please move your mouse pointer to „Wall 1“ in the tab „Scene“ and click with your right mouse button. The context menu opens. Please select „Assign working plane“ (Fig. 67). After this step you can turn the working plane around 180°.“

Fig. 67

Note: The origin of a working plane for walls lies always in the left hand corner as in Fig. 72 (view from inside the room).

Open the menu “Raster properties” and set an appropriate placing grid for the follow-ing steps (0,1m). The next step is the import of a second CAD section to our scene.

Select „File – Import – CAD Plan“ and follow next steps as before. In the Relux-Suite program directory (..\Program Files\ReluxSuite\examples) you will find some example CAD drawings (Profile-UG-EFH.dwg).

Fig. 68 select a file



Fig. 69 define drawing unites

Set the origin point and click the button “Determine”. Just click to the origin and after a successful import you should see the drawing as follows.

2. extrudes a cube based on CAD drawing vectors, or curves.

3. extrudes a working surface based on CAD drawing vectors.

4. extrudes a wall based on CAD drawing vectors. Default thickness is 10cm.

5. creates a virtual measuring area based on CAD drawing vectors.

6. creates a new escape route area based on CAD drawing vectors.

7. creates a new escape route based on CAD drawing vectors.

8. creates a new scene (interior, or exterior) based on CAD drawing vectors.



Note: For an indoor lighting design, we recommend that the design be performed for each floor, or individual room, instead of rebuilding the entire scenery in a single scene. As you can see, however, there are many different possibilities.

4.11 New ReluxMovie Module

4.11.1 Introduction Films can be generated in a particularly easy manner with the animation module in ReluxPro. For this, you simply require the “Animation” toolbar and the animation bar. You can have these displayed or hidden via the Window-Animation Bar and Win-dow-Symbol Bar-Animation menus.

The procedure for compiling an animation has already been described in the “New Re-luxMovie Module” section, which is why we are now setting out the details of these new options.

4.11.2 Animation bar

Fig. 73: “Animation” toolbar



When a new camera position is set, the position of the camera on the time axis is es-tablished automatically on the basis of the specified speed. The positions are shown

on the time axis with the symbol.

The positions on the time axis can be changed manually. To do this, you should move

the controller (black bar), either with the mouse or with the command, until it is

close to a camera position and this changes its colour to red.

Keeping the Ctrl key and the left mouse button pressed in the black area, you can now move the camera position on the time axis. If you additionally press Shift, all the subsequent camera positions will similarly be moved.

A new camera position on the time axis will overwrite an existing camera position.

The duration of an animation is automatically set at 30 seconds. This can be changed in the properties of the animation in question.

There are two ways of showing the time: the number of pictures (1 B., 2 B., …) or in hours, minutes and seconds (hh:mm:ss:ff, SMPTE timecode). The setting for this can be made under the Extras – Options – General Settings menu, under the Anima-tion units in SMPTE Timecode option.

4.11.3 Maintaining the observer height In order to maintain the observer height when the different camera positions are set, a useful key shortcut has been introduced for operation via the mouse and the key-board. As long as you keep the Alt key pressed, the current observer height will be maintained.

4.11.4 Animation path In the 2D and 3D View, the trajectory of the camera between the individual camera positions is shown as a dotted blue/orange path. Each section of line represents a pic-ture. In the Floor Plan View and all other 3D Views, the camera travels along this path when the animation is played.

By clicking on the path, the individual camera positions are shown as blue squares. These squares can be selected and the camera position changed or deleted.

An animation path of this type can be copied, moved and rotated in the same way as an object.



Fig. 74 Animation path

4.11.5 Multiple animation paths The program allows more than one animation to be conducted within a scene.

When you click on one of the camera positions (blue squares) in the 3D View, Relux shows one or other of the animation paths in the “Animation” toolbar.

The 3D camera symbol is shown in red if the associated animation is active. For non-active animations, the 3D camera symbols are shown with blue lines. These are red if the animation is active.

4.11.6 Interpolation Between the camera positions, the path that the camera follows is set automatically. By way of a default, the Akima interpolation is used for the path.

This interpolation can also be switched. To do this, select one of the three interpola-tion functions in the context menu for the animation node in the scene tree:

Linear:

Fig. 75 Linear interpolation

http://www.kxcad.net/CINEMA_4D/help/US/pics/001597.jpg�



The simplest type of interpolation. This connects points by means of a line. The values between the points are established on a linear basis. This generally causes a jolt at the point where the photo is taken.

Cubic:

Fig. 76 Cubic interpolation

This interpolation leads to a soft curve between the points. It guarantees a smooth and jolt-free profile. There can, however, be considerable deviations from the direct link between the photo points.

Akima:

Fig. 77 Akima interpolation

This interpolation type similarly creates a soft curve between the points. The Akima curve remains closer to the direct link, however, than the cubic interpolation.

4.11.7 Stretch-compress animation If you have compiled an animation and wish to compress or lengthen the playing speed of a film, you can select the Stretch-compress function in the context menu for the animation. In the subsequent dialog, you can specify the length in seconds to which the animation is to be stretched or compressed. The animation cannot be com-pressed so far that the individual photo points overlap (Fig. 78).

Fig. 78 Stretch animation





4.11.8 Animation properties By double-clicking on the animation node in the project tree or clicking on the Anima-tion toolbar, you can call up the property window for this animation. The following settings can be made via the dialog (5):

Fig. 79 Animation settings

Frame rate: defines the number of frames per second of film.

Time axis: defines the range that is shown in the animation axis; this can be specified by setting the time to be shown in seconds or the number of pictures.

4.11.9 Rendering the animation An animation path must be rendered beforehand for the film to be obtained. To do

this, select the icon with the film slate-board in the toolbar or select the Extras – render animation option.

The following dialog can be used to make settings for the format and resolution (Fig. 80, Render settings).

Fig. 80 Render settings

Output type: here the user determines the output type with which the film is to be generated. It is possible to choose between “Uncalculated”, i.e. the normal 3D View, or “Luminance distribution” i.e. the calculated 3D View. At the moment, calculated radiosity scenes can be rendered by this method but not raytracing scenes.



Format: Defines the output format for the film. With the “AVI” option, the film is cal-culated in the standard format used for Windows. By clicking on Options, it is possible to select a codec that is available on the computer and also the desired compression stage.

As a further option, the film can also be saved as a series of individual pictures, and it is also possible to choose between “JPEG” and “BMP”.

Resolution: The most common film formats are listed in the selection box. You can also specify the film resolution that you would like via the input fields (width and height).

Duration: Here you decide which part of the animation is to be saved in the film. You can choose either “All pictures” or just “Current picture”. With the input fields of “from” / ”to”, you can limit the animation to a duration that you select yourself.

By clicking on “Start” you call up a dialog which asks you where the target file is to be written to. The user’s video folder is set as the default (My files/My videos). After confirming with OK, the rendering process will be started automatically (Fig. 81).

Fig. 81 Render manager

The Render manager shows the following information:

Number of pictures calculated / Total number of pictures

Time elapsed since the start of the rendering process

Time remaining until the process is completed

Estimated overall time for the compilation process



Path for the film being calculated

The checkbox can be used to show or switch off a preview. The preview shows which individual pictures are being written to the film. The process can be stopped at any time in order to eliminate any setting errors. If the film is to be shown in the Standard Player once the rendering is complete, the “Open after calculation” box must be checked.

Note: It is not possible to continue a rendering process that has been interrupted. The film is not saved in the Relux project file but in a separate file.



4.12 New GR and TI glare rating for outdoors

The glare rating in outdoor projects has been extended in the Calculation manager. Under Artificial light and the Glare rating tab, new GR and TI glare ratings can be calculated for observers.

The following description explicitly covers the verification required by the German Railway (DB) for overground platforms.

Fig. 82 Calculation manager dialog

4.12.1 What is calculated? The direct light from each individual luminaire is calculated at each observer point. This value, set out as a ratio to the surrounding luminance, gives the GR or TI value. The surrounding luminance value is obtained as a function of the defined measure-ment area, referred to as the reference value.

Although this is an approximation, CIE 112 stipulates that it is a permitted approxima-tion.

GR values stand for stationary observer points and TI values for travelling or moving observer points.



4.12.2 Measuring area and observers See Point 1, Fig. 83. To calculate the GR value and the TI values, the program re-quires a Reference area for establishing the surrounding luminances.

The Reference area must be allocated a mean Reflectance of the real area that is positioned underneath it. The program looks for this reflectance automatically. This procedure, as described, makes it possible to establish GR / TI for any desired scenes and at different levels.

Note: Try to avoid dissimilar reflections beneath reference surfaces if possible. If the reflectance of these real surfaces (e.g. the floor) changes, it may be necessary to adjust the reflectance of the reference surface.

Fig. 83 Measurement or reference area

See the above Figure. The observer points arranged like a table represent the waiting passengers next to the railway lines; the observer points arranged in a row represent the conductor of the train that is arriving.

The position and size of the reference area ought always to be selected to suit the re-quirements (sports ground, station platform...). In the picture above you can see the reference area shown in red. Care was taken to ensure that this is lined up in parallel beneath a repeated pattern of positioned luminaires.

The program positions a group of 5x5 observers uniformly in front of the reference area for calculating the GR values.

The observer points for the vehicle driver are positioned in parallel to the reference surface. The first observer point is at an angle of 20° prior to the first luminaire above

the reference surface. In the transverse direction, it is placed 1.66m alongside the left edge of the measurement field (platform edge). The number of steps and the distance between them is governed by the length of the measuring surface and the number of measuring points set. The basic parameters are set in accordance with the German Railway (DB) Guidelines. All the parameters can be adjusted as required.

Note: The observer points are not updated automatically. If the observers have to be realigned due to changes in the luminaire positions or the alignment of the meas-urement surface, you must trigger the automatic positioning of the observer points manually. To do this, go to the Calculation Manager and start DB Guidelines again.

Please note that when GR and TI values are determined for outdoors, all the light re-flections are calculated as in the past, but, according to the method proposed in CIE 112 for determining the mean background luminance, only the reference surface is taken into account. A bright white wall direct in the observer’s field of vision thus only has an indirect influence on the mean background luminance. As a result, the calcu-lated GR and TI values tend to be too high (see CIE112). On the other hand, it is not necessary to recreate every 3D detail in outdoor projects.



4.13 Raytracing calculation in Relux Pro

4.13.1 How to use the Relux raytracing calculation

Fig. 84

Fig. 85

The raytracing calculation is based on a version of Radiance that has been revised by Relux. This verified method, which has been validated worldwide, is noted for its accu-rate calculation results. A ray tracer is a complex tool with many adjustable parame-ters which need to be set by the user. To use the raytracing calculation just open the calculation manager of ReluxPro.

Note: The following chapter provides a short introduction into the use of this calculation method. For more detailed information please refer to our newly completed guide "Radiance calculation with ReluxPro ". You will find this additional guide either on our ReluxSuite DVD, or on our web-site www.relux.biz.

Relux Raytracer offers two modes for doing calculations: in the standard mode the most important parameters are set automatically depending on the chosen quality setting, only the number of diffuse interreflexions can be specified separately. For usual scenes these automatic settings deliver already very good results within accept-able calculation times.

For specific demands Relux Raytracer additionally offers an expert mode, which al-lows to control the program execution separately for the different individual tasks of a lighting simulation like the direct or indirect part of the illumination calculation, or special adjustments for daylight scenes, etckann.

Note: Both modes are independent. This for example offers the option of setting low quality values in the standard mode for quick preview renderings in the chosen



image format and at the same time setting high quality values in the expert mode dialog. Afterwards, one can easily switch between the two ways by simply activating / deactivating the expert mode.

Fig. 86 ReluxPro raytracing calculation



4.13.2 The Standard mode parameters The preparations for a visualization with the "Raytracing calculation" encompasses the same steps as those for a light standard calculations in "ReluxPro " (Fig. 87).

1. Create a new project or add a new scene to your current project

2. Develop the layout of the room with e.g. furniture and wall materials

3. For artificial light calculations: select and position the luminaires of your choice and for daylight calculations: select and position at least one window or a skylight

Fig. 87 Calculation manager (Standard mode)

Once the layout of the scene has been completed, you can go further and open the calculation manager. Further inputs are required here, in the same way as for the standard light calculations. The calculation manager incorporates a switch box to acti-vate the Radiance parameters. Let us first cover the standard settings, starting with the type of calculation:

:

Type of lighting

Artificial light Only luminaires are calculated as light sources Windows are depicted as black surface (night).

Daylight Only The light coming through windows and skylights is cal-culated.



Artificial light and

daylight

All artificial light sources and daylight are taken into ac-count .

As next you’ll find the settings for the daylight calculations with the different sky con-ditions,

together with the date and true local time. The time is converted and also shown as so-called "true solar time (TST)" using the date and the longitude entered in "Project - Location". This essentially determines the position of the sun and therefore the lumi-nance distribution of the sky. If requested you can set the switch button "with sun" to calculate the effect of direct sunlight as well.

Sky type

Clear sky according to CIE Only the radiation of the sky is taken into account, without the radiation due to the sun.

CIE Publication No. 22 of 1973

Intermediate sky according to CIE

A partially overcast sky with the components of over-cast and clear sky being determined on the basis of the sun probability and additional weighting factors.


Overcast sky to CIE The CIE defines an overcast sky with an uneven light distribution here, deviating slightly from DIN 5034 Part 2.


Uniformly overcast sky This sky type has been described in DIN 5034 Part 2 with a specific luminance for all directions, i.e. deter-mined solely by the angle of the point in the sky to the zenith.

In the standard mode you can set as well the Fig. quality as well the number of „In-ter-reflections“ are additionally taken into account. The best possible quality of ren-derings is achieved with „high“.

In the Expert mode, a lot more settings are additionally available. This document con-tains only a summary.

Note: For more detailed information please refer to our newly completed guide "Radiance calculation with ReluxPro ". You will find this additional guide either on our ReluxSuite DVD, or on our web-site www.relux.biz.



4.13.3 The Expert mode parameters

Fig. 88

Fig. 89 Expert mode

The justification of several parameters is the aim to provide the possibility of adjust-ment for all kinds of specific scenarios. In general, dependent on the project, only a few of the values need to be changed by the user. In the following, some guidelines are given to provide you with the necessary background for performing the task of adequate parameter adjustment.

Note: the opportunity of individual parameter settings is both a convenience and a challenge. Consistency of the value settings is of course vital. If, e.g., a high image quality is chosen and at the same time an insufficient spatial resolution for the indirect light calculation is set, the results will likely be not satisfying.



Scene geometry: Parameters in this category in general don't need a user interfer-ence, they are only provided for very exceptional cases in which problems with the geometry export show up.

For the ray tracing process the scene data are converted into a special structure (oc-tree).

The scene is divided subsequently into cubes and sub cubes to provide information about which parts of the overall volume are occupied by objects and which not. An important criterion for this conversion process is of course the ratio of smallest ap-pearing geometry size to the overall scene size. The underlying algorithm however is already capable of handling a wide range of these geometry ratios, so normally the octree resolution doesn't need to be changed. Only in cases in which huge scenes also contain a lot of small geometry detail, especially if this detail appears locally con-centrated, it might be necessary to augment this value (e.g. from 16000 to 32000).

A further geometry-specific adjustment possibility affects the way in which the objects are stored internally. Given the fact that usually scenes are growing more complex with each year, Relux Raytracer by default allocates all objects in a highly compressed data structure. Thus scenes can be rendered now with the new version which would be an impossible task for previous Relux Raytracer versions. Usually, this memory optimization also doesn't need to be changed by the user. (For simple scenes deac-tivating can save around 10 % of the calculation time)

Image Quality: For convenience, even in the expert mode some parameters are still subsumed under the category image quality. Apart from some internal calculation pa-rameters this value also controls the over sampling rate and the image filtering, which is applied to smoothen rough borders and pixel effects in the final image.

Direct Illumination:Concerning the direct part of the overall illumination calculation, presently the options soft shadows and the connected value of the source sub-diRelux Raytraceramount are adjustable by the user. For a realistic image appear-ance, the soft shadows option should remain activated. The subdiRelux Raytracer-parameter then determines how soft the shadows are rendered. Of course a higher amount of subdiRelux Raytracerunfortunately also results in an increase of the neces-sary calculation time

Indirect Illumination: Calculating the indirect part of the illumination is undoubtedly the most complex task of a visualization. Within Radiance, the indirect illumination is also simulated with a ray tracing process, but in contrast to the simple direct ray trac-ing method, in this case rays are sent out not only from the observers point of view, but also from various points within the whole scene. These indirect rays sample the (indirect) illumination reaching the point in consideration from the whole hemisphere above it. One additionally takes advantage of the fact that the indirect illumination varies much less strongly compared to the direct part. Thus it is possible to cache val-ues from the calculation and reuse them for points in the vicinity to a certain amount (interpolation method).

This general approach demands a set of specific parameters, of which the four most important ones can be set in Relux Raytracer:

The number of interreflexions, i.e. up to which depth indirect interreflexions are fol-lowed, the spatial resolution used for the calculation and interpolation process, the number of indirect rays which are sent out to sample the surrounding hemisphere, and finally a value for the background ambient illumination, which serves to simu-late the part of the illumination which is not considered due to the fact that only a fi-nite number of indirect interreflexions are traced.



Theoretically, an infinite amount of interreflexions needs to be considered to simulate the light flux exchange between the scene surfaces in a physically exact manner. To limit calculation times especially for visualizations, one can work with few interreflex-ions and simulate the rest with an ambient background light. In this case, for the practical application, 2-3 interreflexions are recommended for usual scenes. Take for example a simple indirect illumination scenario. With 1 interreflexion, the path lumi-naire -> ceiling -> workplane is sampled, with 2 interreflexions additional paths like luminaire -> ceiling -> walls -> workplane can be considered. The ambient illumina-tion is scene dependent in general, its advisable to make some previews to find out suitable values for typical scenarios. Higher values for the number of interreflexions (3-5) are recommended for scenes with mostly indirect illumination, or if a high calcu-lation accuracy is needed. More than 7-9 interreflexions are generally not advisable, the sampled contributions decrease quickly with higher iteration levels and in the end fall below the general error of the applied stochastic ray tracing method. (clearly, one should reduce the ambient light accordingly when using such a high number of inter-reflexions, or set it completely zero, in order to avoid erroneously adding light to the scene.)

Of course the number of indirect interreflexions has a high influence on the amount of calculation time. For quick preview runs the indirect calculation can be switched off completely (0 interreflexions). Keep in mind that then all surfaces which are not illu-minated by a light source directly are rendered unnaturally dark.

The necessary spatial resolution is a critical parameter which is very much a func-tion of the scene geometry and leads to artefacts in the image if set to inadequate values. The default value of 0.4 m is already a relatively coarse setting to keep calcu-lation times to within reasonable limits. Scenes with a high illumination variance and/or fine detail might need a finer setting (such as 0.2 or, in extreme cases, as low as 0.1 or 0.05). It should be noted that this, unfortunately, rapidly leads to a consid-erably higher calculation time. On the other hand, with artificially illuminated exterior areas, for instance, where the indirect component part plays a more minor role, the value can often be increased (to between 0.6 and 1.0 m, for example) without imme-diately causing image artefacts. The pronounced dependence on the scene geometry and the illumination configuration make it difficult to provide any further general ad-vice. Given the major influence on calculation time, however, it is generally advisable to experiment with different settings.

The number of indirect rays is set to a default value which is adequate for standard scene types (please consult the following chart). What has been said above, however, similarly applies here – a large amount of scene detail and a high illumination variance could necessitate an adjustment (to between 800 and 1000, or more) in order to make sure that all the surrounding details are correctly sampled. With more or less empty scenes and fairly uniform illumination, the value can safely be reduced (to be-tween 300 and 500, or less). The influence on the calculation time is less pronounced than for the spatial resolution parameter (although 1000 rays might sound a great deal, they still only permit a rather coarse sampling of the surrounding objects). Ex-perimenting with different settings is recommended, too. Hence, in the case of scenes that require a fine spatial resolution on account of extensive geometry detail, but which also have only a low illumination variance, it may make sense to reduce the number of indirect rays so as to keep the calculation times within reasonable limits.

Simple scene (artificial and/or daylight with pre-calculation of daylight openings, such as win-dows; good, uniform light)

800 – 1200



More complex scenes (more details; highly var-ied illumination through the use of narrow beam spots und/or direct sunlight)

1500 – 3000

Calculation of daylight without the precalculation of daylight openings such as windows

3000 – 5000

Daylight calculations are generally more challenging, because of the greater vari-ance of the illumination (by comparison to artificially lit scenes). Another difficulty is that the sky hemisphere cannot be treated as a localized light emitter in the same way as a normal luminaire. For this reason, the sky portion of the illumination is evaluated using the indirect light process in Radiance. (By contrast to the sun itself, which similarly cannot be localized, because of its great distance, but which can easily be simulated as an angular light source with a source angle of approximately 0.5°).

To accurately simulate the illumination through daylight openings, it is recommended that a precalculation be run for all the openings (windows and skylights). Each day-light opening is treated separately, and a luminous intensity distribution is generated which describes the angular dependence of the incoming daylight, making allowance for the chosen sky model and all the external obstructions (if modeled). It is, of course, necessary for the level of the external interreflections to be correctly speci-fied. The default (and minimum) value of 1 for the interreflection only takes the sky itself into consideration. All the geometry objects outside the room act as pure ob-structions. With 2 or more interreflections, it is possible to additionally consider the amount of light (from the sun and the sky) which is reflected by external objects.

The precalculation routine thus converts daylight openings into localized light sources, making for a more accurate calculation by comparison to a simulation that uses the indirect algorithm for simulating the room as a whole. These localized sources can, however, produce disturbing highlights in conjunction with reflecting surfaces when images are generated. It is thus possible for this precalculation to be switched off. In this case, it is recommended that the number of interreflections be increased to 3-5 or more (both the interreflections within the room and those outside it must now be con-sidered together). The number of indirect rays can perhaps also be increased (e.g. to 800-1000 or more). Switching off the window precalculation can also make sense for scenes with very large daylight openings, e.g. rooms with large window sections that cover entire walls from the floor to the ceiling.



4.13.4 Set up a viewpoint

Fig. 90 Views

The "Views" dialog page (Fig. 90) has been included to allow a viewpoint to be set up for the raytracing calculation. It also offers facilities for defining additional views and entering the settings for the size of the visualizations. A preview button is provided for the creation of previews..

4.13.5 Raster measuring areas and start of calculation The Relux raytracing module has a "Raster measuring areas" dialog (Fig. 80) for cal-culating luminances or illuminances. This dialog is used in the same way as in Relux-Pro calculations.

The measuring surfaces contained in the project are listed in the dialog, and the basic settings are shown for the number of points in the X and Y direction, together with the corresponding intervals between the points. Pressing the '...' button will activate the extended dialog for selecting the additional "vertical illuminances".

4.14 ReluxEnergy

ReluxEnergy is a powerful free-of-charge module for calculating the energy consump-tion of interior lighting in non-residential buildings. It is based on energy standards, such as EN 15193 and DIN 18599-4 (SIA380/4 & CTE HE-3 will be following in May 2009).

General information: ReluxPro data files can be imported into the ReluxEnergy pro-gram. Once the files have been imported, you then add the extra details regarding consumption and the information that is required by the standards. Changes which are made in ReluxPro data files will automatically be transferred to the ReluxEnergy project as long as you do not move or delete these reference data files.

Note: An overview of the total energy consumption will be provided on the basis of the EN 15193 energy standard. No recommendations are given regarding the maximum overall energy consumption per year at the moment, since there are no recommendations contained in the standard.

An overview is also available for the DIN 18599-4 energy standard, together with a "stop" light which provides direct feedback on whether the DIN standards have been attained or not. In addition to this, ReluxEnergy provides you with the total maximum permitted energy consumption per year, as well as the current energy consumption.

The graphic user interface for ReluxEnergy

Fig. 92: GUI of Relux Energy



Note: To achieve meaningful results, it is necessary to have a basic knowledge of the energy standards, including EN 15193 and DIN 18599-4, when using ReluxEnergy. Relux Informatik AG and their partners in Europe offer frequent training courses on this special field of light engineering. For further information please visit www.relux.biz.

Use of the graphic user interface is highly intuitive. It contains two different tabs.

1. Energy evaluation (see above) is divided into three sections:

Scene explorer, where all the rooms and sections are listed (green outline)

Settings, where the data can be entered for the building and its zones (yellow outline)

Results overview, for the building, individual rooms and sections (red outline)

2. Results: This tab works in the same way as the Print manager in ReluxPro and makes it possible to organize all the project results.

The following two project examples illustrate the capability of ReluxEnergy.

Example 2: project based on DIN 18599-4 General information: the use of ReluxEnergy on the basis of DIN 18599-4 is fairly similar to the procedure for EN 18593. There are, however, two key points that differ in the EN 15893 and DIN 18599-4 standards:

Only the DIN 18599-10 norm contains several “utilization profiles”. These profiles in-clude fixed parameters that cannot be changed by the user. They form part of the standard.

Fig. 105 paragraph from the German DIN 18599-10 standard

The consultant can evaluate the power consumption from the utilization profiles and a recommended maximum power consumption for each profile. The consultant can thus compare their planned power consumption with a reference value (for each individual zone and section).

Follow steps 5 to 17 from the previous example (example 1) (EN 15193) in order to calculate the total power consumption (including per zone and per room) for your pro-ject.

Fig. 107 utilization profiles

Note: The utilization profiles and a recommended maximum power consumption for each

profile make it possible to evaluate the power consumption. The traffic light provides an over-

view of your project (green traffic light = values are within recommended range; red traffic

light = revise concept). There are several options for optimizing the power consumption of

your project.

4.15 Tunnel module

The tunnel calculation software has been developed for experts and is based on the CIE88, CIE140 and SLG201 standards. Knowledge of these standards is necessary in order to evaluate the precise results.

You must purchase a license to run this module. For further information please con-tact us via e-mail at [email protected], or by telephone on +41613330770.

After your tunnel module has been activated via a hardware lock, you can start Relux-Pro and select the “Tunnel“ option from the start menu.

A tunnel project is controlled via the <Scene Bar> and the <Tunnel Bar>. If these happen to be hidden (which is unlikely), you should simply use the “Scene“ and “Tun-nel“ options in the "Window“ fly-out menu to activate them.

Step 1: Tunnel geometry Start ReluxPro and select the project type “Tunnel”. Fill in the basic parameters for the tunnel geometry and the calculation parameters.

Step 2: Luminaires / LDCs You need to insert at least one row of luminaires. Therefore please move your mouse pointer to „Room structure“ in the tab „Scene“ and click with your right mouse button. The context menu opens.

Fig. 111 add luminaires

If you open this option for the first time I your project, the product selection will open automatically. Alternatively you can use the usual ways of luminaire selection.

Note: In the product selection, you can use the Tab: Individual luminaire to import a single LDC file.

After you have added one or more luminaires to the project and closed the product selection again, the configuration dialog for the “Alternative equipment” and “Regulat-ing steps” will open automatically (only the first time).



Fig. 112 Options

In the “Alternative equipment” dialog, you must enter the selected LDC’s to the “Adaption” or “Interior” group. You may create more than one entry in each group.

If you want to use the same LDC with a different flux values you must select it more then once and use the “Modify type” function in the product selection (Fig. 112).

Fig. 113 Modify luminaire



Fig. 114 configure luminaire controlling

The first time the “Regulating steps” dialog is opened, the configuration dialog opens as well. Choose how many Control groups and Regulating steps and the kind of con-trolling you want.

You can change this later by pressing the “configure” button. We currently support three modes of switching the luminaires.

Dimming

(On/Off)

(On/50%/Off)

After creating the row of luminaires, it is possible to insert the basic parameters by selecting the row in the scene bar. If you wish you can create multiple rows, these rows will automatically synchronized, for instance after changing the type of the 4th luminaire.



Fig. 115 Options

By clicking the first icon in the toolbar, you can switch to the luminaire list of the cur-rent row.

Fig. 116 Options

In Fig. 116 you can manually change the control group and the power level of each row.

To begin with, each row will be created with a unique distance between the individual luminaires. In list mode you can modify the x-position of each luminaire. If you select one or more grid rows, you can use the buttons.

to insert a copy of the selected luminaire

this button deletes the selected luminaire

If you activate the shift lock and change the x-position of one of the luminaires, all the following luminaires will also be moved.



Step 3: Calculation There are two ways of running the calculation:

Automatic placing (Button )

(Fig. 117 Tunnel automatic placement) If you select this mode, the program will try to find the ideal position on the basis of the specified parameters and the regulating strategy.

After running this mode, you will find the luminaires of the adaptation rows sorted like this, for example

3 2 1 3 2 1 3 2 1 3 2 1…….2 1 2 1 1 1 1

The program will also place the luminaires with the lower power levels at the end of the row.

For the interior rows, the tunnel module will try to find the optimum distance between the luminaires.

Before the automatic placement starts, a dialog opens which allows you run the opti-mization of interior and entrance separately or together.

Fig. 117 Tunnel automatic placement

For the entrance lighting you have a few options to control the result.

Maximum luminaire distance:

At this distance the program uses the next lower flux level.

Min luminaire dist.

Automatic shift

Hold the initial lum. dist / Lum. dist. At the beginning

This forces the program, to use the given distance in first part of the entrance zone.



Useful to make (small) corrections if the automatic calculated value is not optimal.

Factor length / Factor luminance

The algorithm will work with modified length / entry luminance, this spreads the

nominal curve during the placing calculation.normal calculation (Button )

This command triggers a calculation of the current situation.

Note: at the moment you have to press the button each time you want to re-calculate.

If no measuring area exists in the project, the program will automatically create the three standard areas:

Entrance area: for the constant level in the first part of the threshold zone

Interior area: for the constant level in the interior zone

Adaptation area: for variable levels from the portal to the end of the transition zone

Fig. 118 Calculation specifications

You can modify these manually after the program has created them. At the moment, the program will recreate them automatically when you delete them all. We are going to make this behavior configurable, and will also provide user defined areas.

Step 4: Checking results After the calculation, you will find all the available results for each area and the regu-lating steps in the <output bar>. In the regulating steps dialog, you can choose more than one regulating step to calculate.

You can open the results by using the toolbar “outputs”.

Note: Each time a output window is open you can use its properties dialog to configure its specific options

The “Result overview” output (Fig. 120) contains a summary for all three areas.
