Detailed Description

struct A3DMiscReferenceOnTopologyData

Structure that identifies the referenced topology entity and that specifies globally-defined attributes.

m_puiAdditionalIndexes contains index on different topology elements (see Reference on Topology/Tessellation for explanation)

Version

2.0

For reference on A3DTopoEdge or A3DTopoCoEdge, m_uiSize must be set to 3 and

• m_puiAdditionalIndexes[0] is the A3DTopoFace index in the A3DTopoBrepData
• m_puiAdditionalIndexes[1] is the A3DTopoLoop index in the A3DTopoFace
• m_puiAdditionalIndexes[2] is the A3DTopoEdge index in the A3DTopoLoop

For reference on A3DTopoVertex, m_uiSize must be set to 4 and

• m_puiAdditionalIndexes[0] is the A3DTopoFace index in the A3DTopoBrepData
• m_puiAdditionalIndexes[1] is the A3DTopoLoop index in the A3DTopoFace
• m_puiAdditionalIndexes[2] is the A3DTopoEdge index in the A3DTopoLoop
• m_puiAdditionalIndexes[3] is the A3DTopoVertex index in the A3DTopoEdge.

A3DTopoBrepData *m_pBrepData

Body. Filled by A3DMiscReferenceOnTopologyGet, Can be NULL. With A3DMiscReferenceOnTopologyCreate it can’t be NULL and must be a A3DTopoBrepData.

A3DUns32 m_uiSize

The size of m_puiAdditionalIndexes.

A3DUns32 *m_puiAdditionalIndexes

Indices to retrieve the topological entity.
