Main of them is that it's optimized for cases when topology of base mesh doesn't change. While OpenSubdiv has some really strong points it's still not a magic bullet and has it's own limitations. Supports multiple compute backends, such as CPU, GLSL, CUDA and OpenCL. ![]() Implements nice support of edge sharpness (at least better than Blender was originally doing this).Implements evaluation API which could be used by renderers.Allows to do heavy computation once, and then refine it for an updated coarse positions much more efficient.OpenSubdiv is a library which implements Catmull-Clark surface subdivisions with the following strong points: Coarse positions - coordinates of vertices on the base mesh. ![]()
