Public Attributes
std::size_t	curveIndex
	Index of the geometric curve data.
const Vertex *	previousVertex
	Pointer to the vertex at beginning of curve (previous and next might be the same vertex).
const Vertex *	nextVertex
	Pointer to the vertex at end of curve (previous and next might be the same vertex).
const Face *	face
	Pointer to the face (all half-edges forming a loop will point to the same face).
HalfEdge *	nextEdge
	Pointer to the next edge in a loop (can be a pointer to itself).
HalfEdge *	previousEdge
	Pointer to the previous edge in a loop (can be a pointer to itself).
HalfEdge *	oppositeEdge
	Pointer to the opposite edge (part of the loop of an adjacent face).
bool	reversed
	True if the curve is in the reverse direction. As a pair of half-edges points to the same curve data, one of the half-edges will have to be reversed.

Detailed Description

Half-edge structure.

Each edge in the BREP is represented as a pair of half-edges. A half-edge has pointers to the previous and next vertices, previous and next edges, and a face.
