A3DMiscReferenceOnTopologyData

struct A3DMiscReferenceOnTopologyData

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

2.0

m_puiAdditionalIndexescontains indexes on different topological elements (see Reference on Topology/Tessellationfor explanation).

For reference on A3DTopoEdgeor A3DTopoCoEdge, m_uiSizemust be set to 3 and

• m_puiAdditionalIndexes[0] is the A3DTopoFaceindex in the A3DTopoBrepData
• m_puiAdditionalIndexes[1] is the A3DTopoLoopindex in the A3DTopoFace
• m_puiAdditionalIndexes[2] is the A3DTopoCoEdgeindex in the A3DTopoLoop.

For reference on A3DTopoVertex, m_uiSizemust be set to 4 and

• m_puiAdditionalIndexes[0] is the A3DTopoFaceindex in the A3DTopoBrepData
• m_puiAdditionalIndexes[1] is the A3DTopoLoopindex in the A3DTopoFace
• m_puiAdditionalIndexes[2] is the A3DTopoCoEdgeindex in the A3DTopoLoop
• m_puiAdditionalIndexes[3] is the A3DTopoVertexindex in the A3DTopoEdgereferenced by the A3DTopoCoEdge. Is set to 0 for the start vertex, and 1 for the end vertex.
