Member Data Documentation

◆ build_mutex

Mutex blender::bke::mesh::CornerNormalSpaceArray::build_mutex

Results are added from multiple threads. The lock is an easy way to parallelize adding results for each corner fan. This method means the order of spaces in the spaces vector and corners_by_face is non-deterministic. That shouldn't affect the final output for the user though.

◆ corner_space_indices

Array<int> blender::bke::mesh::CornerNormalSpaceArray::corner_space_indices

The index of the data in the spaces array for each face corner (the array size is the same as Mesh::corners_num). Rare -1 values define face corners without a coordinate space.

◆ corners_by_space

Vector<Array<int> > blender::bke::mesh::CornerNormalSpaceArray::corners_by_space

A map containing the face corners that make up each space, in the order that they were processed (winding around a vertex).

◆ create_corners_by_space

bool blender::bke::mesh::CornerNormalSpaceArray::create_corners_by_space = false

Whether to create the above map when calculating normals.

◆ spaces

Vector<CornerNormalSpace> blender::bke::mesh::CornerNormalSpaceArray::spaces

The normal coordinate spaces, potentially shared between multiple face corners in a smooth fan connected to a vertex (and not per face corner). Depending on the mesh (the amount of sharing / number of sharp edges / size of each fan), there may be many fewer spaces than face corners, so they are stored in a separate vector.
