Sand dune/Medial Axis (SAMPLE)

Here is a script replicating the shape created by pouring sand on a closed shape (here a polygon). From above it draws medial axis, but here it is a Brep generated from a closed polyline. The limit…Continue

"here is the approach with Sub-d from Rhino Serengeti/Sub-d/6. https://discourse.mcneel.com/t/sub-d-discussion/41341/31 If you just need to keep mesh, use Catmull-Clark from weavebird plugin http://www.giuliopiacentino.com/weaverbird/ I join a file…"

Toyo Ito & Associates Tama Art University Library

Following this discussion http://www.grasshopper3d.com/forum/topics/arcs-on-curves?xg_source=activity here are some other elements to replicate arches styles of Tama Art University Library. I didn't try to replicate the sloping floor. 

First the arches,  I used 7 points Weighted Nurbs Curves with 5 points with a weight of 1 and 2 points with a variable weight (0.66 seems to be a…

Maze Bowl

From virtuality model to reality for a maze bowl : 

After some encouragements in August 2016, I decided in December 2016 to made a real Maze Bowl similar to this one

http://www.grasshopper3d.com/photo/maze-bowl?context=album&albumId=2985220%3AAlbum%3A1529788

Here is the steps I had to get through in order to make it for real. 

I began with a simple…

YANG : Yet Antother Node Generator

After some rework of a previous script (http://www.grasshopper3d.com/forum/topics/smooth-junction-blend-a-minimum-of-4-extrusions) to make node, here is a component to create node to join struts. It generates surfaces which blend sections of struts . 

22/12/2015:  Please consider it as WIP. Comments are welcome. As I have more comments when it works, it is also good…

Veinization

Program to transform mesh and offsets of this mesh in polylines which converge to the last offset (volume near 0). I called that veinization because it is like vein, not nerves nor venation. It requires Millepede plugin for isosurface calculation, Shrotest Walk and Mesh Edit. 

Polylines can be converted to spline and curvepiping applied like in the last image. 

Sort of medial axis are generated, not perfect :-( They are used to link shrinking zones…
