PolyMesh

A lightweight half-edge data structure.

Best used with glm and glow.

TODO

• Properties
• Algorithms
• Tests
• std::less and std::hash for _index (and maybe _handle)
• attribute transformations (also between different types)
• Debug: store compactify generation in handles to check for invalidation
• Debug: insert is_removed assertions into handle access
• Switch primitives and valid_primitives, check if compact flag is inlined
• Test self-adjacent faces
• smart ranges: filter, map
• vector, set, map -> range
• opposite edges (from vertex)
• cotangens weights etc.
• smoothing
• make handle.() contain only valid ones and provide an all_() version
• _copy versions of topological operations that copy attributes
• vertex split?
• half-edge collapse
• normal, tangent, bitangent computation
• attribute iterator
