For one of my plugins, I need to know the connectivity of the UVs of a polygon object.
I know how to get UV coordinates from the UVW tag. As far as I can tell, however, this is just given in a "polygon soup" format, with no connectivity information. (Which makes sense, since the UV topology/connectivity may differ from the mesh topology, i.e., there may be UV seams.)
When two polygons share a vertex, I would like to determine if they also share the same UV vertex. My idea for determining this is to look at the UV coordinates of the two "polyvertices" and determine if their UV coordinates are the same (within some tolerance). Before I implement this, I just wanted to check if there are any built in functions for this, perhaps something similar to the neighbor class, but for UVs?
