Syntax
class FTopologyProvider
Remarks
FTopologyProvider provides selectable edge/group/corner information for FMeshTopologySelector to use. Users should implement a concrete subclass based on the type of mesh topology they wish to make selectable (e.g. group topology, boundary curves, etc.). Then creating a new TopologySelector subclass should be fairly trivial.
