WEEK 2

Mesh

mesh & weld mesh & smooth mesh

Original mesh ad the resulting shapes from changing numerical values of strength and iterations

Vectors

Curve & planar & offset & boundary surfaces & extrude

98

Contour

Brep & contour

Changing the distance in the contour command increase or decrease the number of lines

Useful in showing topography

Curves and intersections

Sphere & populate gometry & jitter & explode tree & circle 3 points

Connected A, B, C inputs of circle 3 points to different outputs of explode tree.

1110

Addtion of loft command

Circle 3 points (graft and simplfy)

Changing radius lengths

1312

WEEK 3

Gridshell

Curves & divide & explode tree & arc 3 points & rebuild & loft & geodesic & shift

Original lofted arc

Different connections of explode tree outputs to geodesic inputs

Tree data list

Sphere & divide surface with output grafted and simplified & relative item & polyline & boundary (with tree statistics, & text tag as indicators)

Changing the relative offset for item combo

1514

Hyperbolic shapes

Points & circles & divide curve & shift & line & loft

1716

Sphere & divide surface & line sdl & pipe/octree

dfferent types of caps on pipes

1918

WEEK 4

Image sampling

Squaregrid & image sampling & circle & flip

2120

Fields

point & point charge & merge fields & tensor display

positive - moving away from piont negative - moving towards point

Direction display

one point

multiple points

2322

varying scaling factor

2524

WEEK 5

Point polar - xy=pi, z=rad, d=golden ratio & interpolate curve & loft & mirror

2726

Voronoi extrusion

Point & series & cull & voronoi & scale & divide curve & nurbs & boundary & extrude

2928

WEEK 6

Tetrahedral curves

Polyon & multiple [debrep & scale & solid difference & brep] & debrep & wires & evaluate curve & jitter & bezier span

3130

WEEK 7

Clusters nurbs

Surface divide & cluster & nurbscluster - surface closest points & move

3332

Smooth curves

Cluster - surface closest points & move & vector2point & cross product & move

the efftect of ungraft-ing in both cases 3534

WEEK 8

Kangaroo experimentation

Line segments & springs from lines & kangaroo physics & negative z unary force representng gravity

Folding a plane

Mesh & weaverbird join mesh and weld & weaverbird edges & springs & kangaroo & points

3736

Mesh relaxation

Mesh & weaverbird join mesh and weld & weaverbird edges & length & multiplication & springs & kangaroo & demesh & naked vertices & item

no control points results in sepa-rated meshes

Additional iterations of case study

lofting without grafting therefore centre piece is not highlighted

outcomes are not smooth, very sharp appearance, repelling people from going closer
