Here's another example of a new component. I've noticed many of the posted definitions that require you to link a surface created in rhino fail if you input a trimmed surface. This example creates a sort of "displacement" on a given trimmed surface. It uses two graphs to deform the surface, one graph for the U direction and another for the V direction. The graphs have been greatly improved in its ease of use. It would be nice if it had inputs for the domain like the gradient component. http://grasshopper3d.googlegroups.com/web/surfacedisplacement.jpg http://grasshopper3d.googlegroups.com/web/surfacedisplacementdef.jpg
