Shrink Wrap with Grasshopper and Kangaroo

This definition approximates a shrink wrap for generic brep geometry.

There are two steps:

The first step creates a mesh from a bounding box and drags each vertex to the closest point on the brep. Andrew Heumann offered a similar definition back in December (http://www.grasshopper3d.com/video/shrinkwrap-with-grasshopper?xg_source=activity)

The second step takes the original vertices of the mesh and treats them as anchor points (since they are now 'attached' to the geometry). The mesh is then triangulated and subdivided and a negative pressure is placed on the new faces with Kangaroo.

We wanted to test the definition on complex geometry. The base geometry is a random structure produced with Rhinoscript.

Collaboration with Jon Bailey (http://archimorph.wordpress.com/)

Comment by David Stasiuk on October 27, 2011 at 2:06am: fantastic!

Comment by RWNB on October 26, 2011 at 6:43am: hello eric,

has you can see, a lot of interest for your "WORKS".
However, if you would tell more about your works,
we would all be thankful.

by sensory continue such great work!

Comment by Pieter Segeren on October 25, 2011 at 2:59pm: Great, I love it, looks real cool.

Comment by madmax on October 25, 2011 at 2:37pm: great work!
