Q3Mesh_FirstVertexFace

You can use the Q3Mesh_FirstVertexFace function to get the first face around a vertex.

TQ3MeshFace Q3Mesh_FirstVertexFace (
TQ3MeshVertex vertex, 
TQ3MeshIterator *iterator);

vertex

A mesh vertex.

iterator

A pointer to a mesh iterator structure.

DESCRIPTION

The Q3Mesh_FirstVertexFace function returns, as its function result, the first face around the vertex specified by the vertex parameter. The iterator parameter is a pointer to a mesh iterator structure that Q3Mesh_FirstVertexFace fills in before returning. You should pass the address of that structure to the Q3Mesh_NextVertexVertex function.
