Public Attributes

std::size_t curveIndex
 Index of the geometric curve data.
 
const VertexpreviousVertex
 Pointer to the vertex at beginning of curve (previous and next might be the same vertex).
 
const VertexnextVertex
 Pointer to the vertex at end of curve (previous and next might be the same vertex).
 
const Faceface
 Pointer to the face (all half-edges forming a loop will point to the same face).
 
HalfEdgenextEdge
 Pointer to the next edge in a loop (can be a pointer to itself).
 
HalfEdgepreviousEdge
 Pointer to the previous edge in a loop (can be a pointer to itself).
 
HalfEdgeoppositeEdge
 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.
