Catmull-Clark subdivision

[Al_N_]

In your displacement tutorial example code, what would happen if we could turn off the Catmull-Clark subdivision function? for example, if the rtcNewSubdivisionMesh() function had a parameter to turn off Catmull-Clark. Does the user displacement function Embree calls with x number of points are the actual vertices of the new geometry done by the Catmull-Clark function? Basically, what are the points? just any random position on the mesh?

You probably need displacement on triangle meshes? This is not supported currently.

The displacement callback function is called for a number of points on the smooth catmull clark subdivision surfaces. The callback function can move these points. For quads in the original subdivision mesh, the points form a regular grid pattern.
