Shrink Wrap with 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_s...)

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 pressure value is placed on the new faces with Kangaroo.

Uses Kangaroo and Weaverbird. This is still in development, so please let me know about any issues with the definition.

Update (03232014):

Here's an updated file which will work with the current version of Kangaroo. This definition also uses UTO's Mesh Tools. Use the same 3DM as above and let me know if you run into any issues.

Comment by daniel koene on October 31, 2011 at 1:00am: can this shrink wrap be done in reverse? so it inflates into a shape but deforms when colliding with the shape. for example a sphere in a box.
