Detailed Description
This class defines a method of removing cells and their associated constraints from a Pbd object. Can update the visual and collision representation when using a tetrahedral mesh as physics object Does not support updating visual and collision representation when the physics mesh is a LineMesh or a SurfaceMesh AND they differ. Note: The two modes for visual meshes exist to support generating new texture coordinates, when reusing a vertex from a visual mesh the vertex should already have uv coordinates assigned to it. Assigning new ones may break the current look of the object as the vertex may still be in use. With the VisualSeparateVertices mode, new vertices will be generated for newly exposed surface. This allows the user to assign new uv coordinates to those new points.
