1 STUDIOAIR
LOFTING - Grasshopper
2STUDIOAIR
LOFTING - OPTIONS
loose
tight
uniform
closed loft
straight
developable`
Normal
Exploring loft - Viewing different options to see the differences
3 STUDIOAIR
LOFTING - Further
Further exploration, changing base shape to form complex shapes
4STUDIOAIR
TRIANGULAR ALGORITHM
Experimenting - Curve to points, Points to Lines
5 STUDIOAIR
TRIANGULAR ALGORITHM
2D pattern experiment
6STUDIOAIR
TRIANGULAR ALGORITHM
2D pattern experiment 3D pattern experiment
7 STUDIOAIR
POINTS, VECTORS AND PLANE
8STUDIOAIR
Exploring points, vector and plane
Panel showing its 3 coordinates and vector display,
Unit vector changing the length of the vector, but not changing its direction
Points used to position
Vectors to describe direction and magnitude,
Plane used to describe orientation
9 STUDIOAIR
Creating mesh from scretch
Quad component isn’t practical as it need to set the points need data tree.
Mesh 1.
10STUDIOAIR
Mesh 2.
breping the solid and converting to meshes to utilise mesh welding and smooth mesh
11 STUDIOAIR
adding 2 vectors in grasshopper
ADDITION OF 2 VECTORS
12STUDIOAIR
LINEAR CURVE 1
closing curve with open 2 curves
13 STUDIOAIR
LINEAR CURVE 2
using discontinuity component and average component
14STUDIOAIR
LINEAR CURVE 3
using offset and planar component to create some frames
15 STUDIOAIR
LINEAR CURVE 4
16STUDIOAIR
evaluating the curve observing where the points are on line
Perpendicular component, allowing object to be created (in this case circle) in perpendicular to something (eg curve)
17 STUDIOAIR
3D CURVE
dividing curves in to points allowing arc to form further divided into segments to create grids
using polyline, giving straight line, ie easier to fabricate
18STUDIOAIR
3D CURVE - LOFT
lofting with changing parameters from horizontal to vertical.
somehow showing planes as well as dots, but working exactly same as tutorial video, just showing extra planes
19 STUDIOAIR
3D SURFACE TO 2D PROJECTION
using project component, producing 2 dimensional panel.
20STUDIOAIR
CONTOUR AND LOFT
using move and loft to create same functionality of extrude.
21 STUDIOAIR
CONTOUR TO LAYERS OF RECTANGLE
22STUDIOAIR
3D MODEL TO CONTOUR TO SPEAD
exploring contour component with XY unit and loft
also laying out the 2d panels and lay out parametrically.
23 STUDIOAIR
3D MODEL AND MORPHING
box morphing with loft, checking with face boundaries and planar surface to be sure that the meshes are not distorted.
24STUDIOAIR
INTERSECTION
finding intersection through brep/ brep and using surf split and itemlist to make small wedges that shows there are no leaking point
25 STUDIOAIR
using notches to create detail and cut
3D MODEL NOTCHING
26STUDIOAIR
JOINING THROUGH OFFSET AND LOFT
27 STUDIOAIR
SUBTRACTION
28STUDIOAIR
CONTOURING
Above argorithmic represents the left contour and bottom representing other. For bottom one, even there are no error the result was different to tutorial video. It could be because of “surface” i have used, as i used a lofted surface, since extruded surface didn’t not work.
29 STUDIOAIR
CURVE INTERSECTION
reducing circle number -> circles gone red as random circles are created that does not even fit
30STUDIOAIR
2D PANELING - Exploring
Experimenting with grasshopper, placing object/ shapes/ panels on a surface.
Failed as panels are interseting in the middle. Probably due to 3D object used on panel that had exceeding height - angle or surface.
31 STUDIOAIR
2D PANELING - Exploring
32STUDIOAIR
2D panel, by using Surface divide, decompose, domain divide and morph.
Decompose had to be set was “expression” value of 0 to make the guideline on surface to be flat and keep it as single line, If it was on it made multiple lines and panels intersected/crashed each other like the previous practice.
below is the shape the is used for panel.
