Q3Mesh_FirstFaceEdge

You can use the Q3Mesh_FirstFaceEdge function to get the first edge of a mesh face.

TQ3MeshEdge Q3Mesh_FirstFaceEdge (
TQ3MeshFace face, 
TQ3MeshIterator *iterator);

face

A mesh face.

iterator

A pointer to a mesh iterator structure.

DESCRIPTION

The Q3Mesh_FirstFaceEdge function returns, as its function result, the first edge of the face specified by the face parameter. The iterator parameter is a pointer to a mesh iterator structure that Q3Mesh_FirstFaceEdge fills in before returning. You should pass the address of that structure to the Q3Mesh_NextFaceEdge function.
