Publisher's Description
This is an ICE compound node that computes surface curvature for a polygon mesh. You get positive output values for convex (outward) curvature, negative ones for concave (inward) curvature. Use the output values (scalar) to control whatever parameters you want:

e.g. weightmaps for texturing...
..use the compound set to "concave only" (customized compound) for quick ambient occlusion (not really ao but similar)
..control surface appearance depending on curvature (like some plastic getting brighter when bent)

e.g. particles
..drive particle instance orientation using the curvature values
..emit particles from outward curved parts of the mesh only (e.g. for cellular visualization)

Further instructions inside the compound!
