Detailed Description

struct A3DTopoCoEdgeData

Co-edge structure.

The following values are defined for the m_ucOrientationWithLoop (orientation between edge and loop) and m_ucOrientationUVWithLoop (orientation between uv_curve and loop) members:

Version

2.0

• 0: Opposite orientation
• 1: Same orientation
• 2: Unknown orientation

Note

The m_pUVCurve member must either reference a curve of type kA3DTypeCrvNurbs, or it must be NULL.

Note

Neighbors are connected one to one in a cyclic linked list. No pointer can be repeated in that list.

Public Members

A3DUns8 m_ucOrientationWithLoop

A3DTopoEdge *m_pEdge

Pointer to A3DTopoEdge.

A3DCrvBase *m_pUVCurve

Pointer to parametric space curve.

A3DTopoCoEdge *m_pNeighbor

Pointer to list of neighbors.
