Description

The AcBrVertexLoopTraverser class is the interface class for vertex loop traversers. It is used to seed an upward hierarchical traversal from a specific vertex; to combine upward and downward hierarchical traversals for the radial faces around a vertex in conjunction with an AcBrLoopVertexTraverser; or to handle singularities (such as the apex of a cone, where there is no edge geometry). The order of loops around a vertex is persistent and is consistently counter-clockwise .

Remarks

Because each loop belongs to exactly one face, this traverser provides (with one level of topological indirection) all of the faces adjacent to a vertex; although it is up to the user to filter for duplicate entries.
