Hi Joel,

  No, Chimera does not compute surface curvature.  It would not be too hard to make a Python script that computed it and used it to color a surface.  The main trouble is defining numerically the curvature for a triangulated surface at each vertex.  Why are you interested in this?  Is the idea to simulate ambient occlusion lighting where surface cavities are dark and projections are brighter?  Is the idea to try it on EM maps or molecular surfaces?

	Tom
