LOFTING AND STATE CAPTURE

THIS EXERCISE HAS TAUGHT ME ABOUT LOFTING IN GRASSHOPER. I FOUND HTAT IT IS MORE CONVE-NIENT TO USE GRASSHOPER TO LOFT AN OBJECT THAN LOFTING DIRECTLY ON RHINO. IT HAS A GREAT COMMAND “BAKED” FOR COPYING OUT A SURFACE AND CAN CONTINUE EDITING ON THE CURVES. MY 9 ATTEMPTS HAS BEEN GOING THROUGH MOVING SOME OF THE CONTROL POINTS, WHICH PRESS “F10” TO TURN ON THE POINTS AND DRAG THEM. ALSO, MOVING THE LINES DIRECTLY UP AND DOWN TO TRY DIFFERENT LOCATION. AS WELL AS TO CLICK “LOFT OPTIONS” TO TRY A BIT ON THE RELATIONSHIP BETWEEN THE CURVES AND THE SURFACE. I HAVE TRIED ‘LOOSE’, ‘TIGHT’, ‘STRAIGHT’ AND ‘DEVELOP-ABLE’. THEY ALL GIVE VERY DIFFERENT OUTCOME. IT IS A GOOD WAY TO EXPLORE DIFFERENT SHAPE OF THE STRUCTURE.

CLOSED LOFTING AND DEVELOPABLE SURFACES

THIS EXCERCISE IS TRYING TO CREATE 3D CLOSED LOFTING IRREGULAR GEOMETRIES WITH DEVELPA-BLE SURFACES, A STUDY FROM AA DRIFTWOOD PAVILION(2009). FIRSTLY, A CLOSED LOFT GEOMETRY WAS CREATED AT RHINO. THE USING ‘BREP’ ON GRASSHOPPER TO LINK WITH THE CREATED GEOM-ETRY. A SIMILAR SHAPE’S CURVE WAS DRAWN INSIDE THE LOFTED GEOMETRY AND LINKED WITH OFF-SET TO MAKE PLANTY OF LINES WHICH WILL BE PROJECTED AND CUT ONTO THE GEOMETRY TO CREAT THE DEVELOPABLE SURFACES. THEREFORE, THE NUMBER OF LINES AND DISTANCE BETWEEN EACH LINE WERE IMPORTANT. THEY WERE VARYING BY INPUTTING NUMBERS TO A ‘SERIES’ WHICH WAS LINKED TO THE ‘OFFSET’. THEN EXTRUDING THE OFFSETTING LINES TOWARDS Z COORDINATE COVERED UP THE WHOLE GEOMETRY, JUST LIKE CUTTING THE GEOMETRY INTO PIECES. AFTERWARDS, DVIDING THE CURVES OF THE BREP AND EXPLODING THEM INTO 2 ELEMENTS AND USING SURFACE SPLIT TO SEPA-RATE THEM INTO SINGLE SURFACES.

CONTOURS

CONTOURS CAN MAKE A 2D PLAN INTO A 3D FORM. I TRIED PLAYING WITH CONTOURS ON A 3D SUR-FACE. IT SEEMS CUTTING THE SURFACE HORIZONTALLY AND LOOKS LIKE IT IS THE EXTENSION OF ORIGINAL CURVES BEFORE LOFTING. THEN WHEN I TRIED TO LOFT ALL THE CURVES BACK, IT GIVES A VERY DIFFERENT STRUCTURE. THE CURVES ARE JOINNIGN TO THE OPPOSITE SIDE TO MAKE UP LAY-ERS OF SURFACES. SINCE THE SEQUENCE OF THE CURVES ARE FORMED DIFFERENTLY, SO DIFFERENT STUCTURE WILL BE CREATED.

TRANSFORMATION

IN THIS EXERCISE, I AM LOOKING FOR A DIFFERNT TRANSFORMATION METHOD WHICH IS MORE PARA-METRICALLY DESIGNED. FIRST ATTEMPT, BOXES ARE MADE ON A SURFACE WITH 24 ON BOTH U AND V DIRECTIONS. THEY ARE ALL JOINT TIGHTLY SO IT COULD BE FABRICATED TO MAKE A PHYSICAL STRUCTURE WHICH LOOK LIKE A PAVILION. THOSE BOXES CAN BE REMOVED INDIVIDUALLY, SO OPEN-INGS CAN BE MADE. HOWEVER, THERE WILL BE PROBLEM FOR A INTERSECTION PART WHICH BOXES MIGHT MERGE INTO EACH OTHER, SO CORNERS COULD NOT BE TOO ANGULAR. SECOND ATTEMP, I USED MESH SURFACES MORPH INTO SURFACE BOXES TO CREATE A PANEL STRUCTURE. IT COULD BE A CEILING INSTALLATION OR DECORATION ON WALL. VARIATIONS OF SHAPE CAN BE MADE AS MESH TO BECOME CREATIVE PANELS.

CURVE INTERSECTIONS

IN THIS EXERCISE, IT IS LOOKING AT MAKING INTERSECTION CURVES WITH CONTROLLED SPACING AND ALSO HOW WE MAKE JOINT BETWEEN THOSE INTERSACTIONS. A TIMBER STRUCTURE WITH BOLT JOINT WAS CONSIDERED. FIRST, I USED DIVIDE CURVE COMMAND TO CONTROL THE NUMBER OF POINTS ON EACH INDIVIDUAL CURVE. SINCE THERE ARE THREE CURVES SO I SEPARATE THEM INTO TWO SURFAC-ES SHARING ONE CURVE IN THE MIDDLE. THEN I INSERTED ARCS BETWEEN CURVES POINTING TO Y-DIRECTION AND DIVIDE LENGTH WITH SPACING OF 24. AT LAST FLIP THEM TO INTERSACT EACH JOIN-ING CURVES TO MAKE GRID PATTERN.

SINCE TECTONIC PROPERTY IS IMPORTANT FOR PARAMETRIC DESIGN, I AM LOOKING AT THESE CURVES WHICH ARE PRETENDING TO BE TIMBER STRIPS, BOLT JOINTS ARE USED TO CONNECT AT ALL THE INTERSACTING POINTS. ‘MULTIPLE CURVES’ WES SET TO SOLVE INTERSACTION EVENTS FOR MULTIPLE CURVES. LIST OF ITEMS AND EVALUATION OF CURVES ARE INSERTED TO KEEP CONTROL ON THE IN-TERSECTING CURVES. THEN CREATED PLANE ON X,Y AXES AND PLACED A CIRCLE ON IT TO MAKE THE INTERSECTING POINTS MORE OBVIOUS. A PERPENDICULAR LINE, WHICH IS THE BOLT, WAS DECOM-POSED ONTO THE PLANE.

GRIDSHELL

Here in this exercise is playing with intersecting lines and by shifting points on a curve to various point on another cuve will form that intersecting outcomes. Then to obtain various outcomes, I have been adjusted more divide points on curves and using pipes and giving it thickness to the curves.

FRACTAL TECTRAHEDRAL

In this exercise, we learnt to make tectrahedral form which repeating its singling form into a combination form. It requires mathematics input of pythegoras theorem to obtain a recurvsivable polygon. The method of typing in math-ematics theorem is a good thing to explore.

EVALUATING FIELDS AND GRAPH-ING SECTION PROFILESHere we learnt how to make biomimicy form by playing with fields. Using Point Charge and Field line to get a field pattern. It can be varied by number of divided points on a curve, Point charge value, number of Field lines etc. There are a lot of variables. It also changes when pulling points on curve vertical to form 3D shape. Other than that, graphing section profiles will give more interesting outcomes. It can let us to vary the lines curvature and so to make the form having a curve surface instead of plain flat surface.

GRAPH CONTROLLER

We have learnt how to make patterns curve by varying the graph mapper. Here I have used Beizer, Gaussian and Power graph type to obtain these outcomes.

IMAGE SAMPLING

AA DRIFTWOOD FRAMES

- 19 -

It helps to deal with fabrication and construction process with sectioning methods. Howver the joints will be exposed with using frame.

ARANDA LASH - CONTINUOUS PATTERNING

- 20 -

It continues with fractal tectrahedral. This definition teaches us to make a more complicated chain using the same samic form in to a continuous pttern.

FRACTAL PATTERNS

- 21 -

Clusters are used in this fractal patterns exercise. It is very useful when there are large amount of structure which wanted to be repeat. It allows us to make simple lines into a branch of complicated but basing on a structural for-mat form.

- 22 -

PATTERNIING LIST

- 23 -

Patterning list allows us to play with different patterns on a surface. It various a lot by varying the cull patern and partition where we want to join up the lines, which is used to make a continuous pattern surface.

- 24 -

TRAVELLING SALESMAN - CLUSTERS AND HISTORYTravelling salesman is not one of the required tutorial task but I found it was quite interesting. It helps us to link up with points at the nearest position and by using clusters we can quickly join up all the points on a surface.

VOUSSOIR CLOUD

Our group has been tackling with voussoir cloud definition previously. We were able to play with different plugin us-ing the Kangaroo tools, such as damping, cutoff, hydro etc. They always have different forms which are unexpected. It is very useful for designing dynamic forms.
