skinning.utils.symmetry module

class skinning.utils.symmetry.Symmetry(node)

Bases: object

Create a symmetry map for a provided mesh using an edge that lies on the symmetry plane. This map can be used to link a face, edge or vertex index to its symmetrical counter part. The face, edge and vertex mappers are stored at a class level which will result in a cache that can be used when to be able to use the symmetry class multiple times without having to recalculate the mapping.

calculate_symmetry(edge_index, use_cache=False)

Parameters:

• edge_index (int) –
• use_cache (bool) –

Raises:

RuntimeError – When mesh is not symmetrical.

classmethod clear()

Clear any symmetry data stored on the class, this will make sure that any symmetry data needs to be freshly calculated.

static filter(data, mode=0)
