Detailed Description

template<typename T>
struct blender::meshintersect::CDTVert< T >

Define a templated 2D arrangement of vertices, edges, and faces. The #SymEdge data structure is the basis for a structure that allows easy traversal to neighboring (by topology) geometric elements. Each of CDTVert, #CDTEdge, and #CDTFace have an input_id set, which contain integers that keep track of which input verts, edges, and faces, respectively, that the element was derived from.

While this could be cleaned up some, it is usable by other routines in Blender that need to keep track of a 2D arrangement, with topology.
