Detailed Description

UV Islands for pbvh::Tree Pixel extraction. When primitives share an edge they belong to the same UV Island.

Note

Similar to uvedit_islands.cc, but optimized for pbvh::Tree painting without using BMesh for performance reasons. Non-manifold meshes only (i.e. edges must have less than 3 faces).

Polygons (face with more than 3 edges) are supported as they are split up to primitives.

Note

After the algorithm is stable the OO data structures should be converted back to use DOD principles to improve reusability. Currently this is not done (yet) as during implementation it was hard to follow when the algorithm evolved during several iterations. At that time we needed more flexibility.
