Grasshopper
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_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 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.

the download link is down any way to fix this? love to have this script it's very impressive.

Is there a way to start with a triangle mesh instead of breps?
I know that Daniel Piker has a solution to this, but he hasn't shared his definition (yet)

Hello! I can say that packaging goods and products in shrink film is an excellent solution for any type of business. And if your product flows have currently increased significantly, you need to think about introducing shrinkwrap technology into production. I recommend that you learn more about automated tech in shrinkwrap machinery, because this solution will allow you to increase production speed and save money on hiring employees. Contact a member of the Kempner team to find the best solution for your equipment selection.
