So I have a custom deformer that slides points along a nurbsSurface. I've gotten it to be very optimized, but the major bottleneck is the calling the "getDerivativesAtParm" method for each deformed vertex, and the fact that it can't be multithreaded. I know that MFnNurbsSurface is generally not threadsafe but since the nurbsSurface isn't being deformed I'm wondering if there's another nurbs library or something that I can convert the nurbs data into and then multithread the queries that way. I know that's quite a vague question, but I've never really used c++ outside of the Maya API, so I'm not even sure where to begin on something like this.
