Maybe this should go in the "Data Visualization" thread... It's based on an example from Rhinoscript101 which uses vertex color to show the proximity between points on a mesh cube and a reference surface.
The results are more practical than exciting, but everything updates in real time when the orientation of either the cube or the surface is modified. http://groups.google.com/group/grasshopper3d/web/proximity.png http://groups.google.com/group/grasshopper3d/web/proximity_110508.ghx taz On Nov 5, 5:05 pm, Rchitekt <[EMAIL PROTECTED]> wrote: > pretty cool stuff...
