Q3Mesh_FirstFaceVertex
You can use the Q3Mesh_FirstFaceVertex function to get the first vertex of a mesh face.
TQ3MeshVertex Q3Mesh_FirstFaceVertex (
TQ3MeshFace face, 
TQ3MeshIterator *iterator);
face
A mesh face.
iterator
A pointer to a mesh iterator structure.

DESCRIPTION
The Q3Mesh_FirstFaceVertex function returns, as its function result, the first vertex of the face specified by the face parameter. The iterator parameter is a pointer to a mesh iterator structure that Q3Mesh_FirstFaceVertex fills in before returning. You should pass the address of that structure to the Q3Mesh_NextFaceVertex function.
