Hello, i’m implementing the catmull-clark subdivision algorithm, and the direct11sdk seems to have a demo about that.
i have question when deal with the uv calculation.
if a mesh unwrapped to several uv sets, when we subd the mesh, some newly added vertices are created at the middle of each edge. but, if the edge is shared by two different uv set, which means the two end vertices of this edge has more than one uv coordinates.
Then how to get the uv coordinate for the newly added vertics?
