Q3Mesh_FirstFaceContour

You can use the Q3Mesh_FirstFaceContour function to get the first contour of a mesh face.

TQ3MeshContour Q3Mesh_FirstFaceContour (
TQ3MeshFace face, 
TQ3MeshIterator *iterator);

face

A mesh face.

iterator

A pointer to a mesh iterator structure.

DESCRIPTION

The Q3Mesh_FirstFaceContour function returns, as its function result, the first contour of the face specified by the face parameter. The iterator parameter is a pointer to a mesh iterator structure that Q3Mesh_FirstFaceContour fills in before returning. You should pass the address of that structure to the Q3Mesh_NextFaceContour function.
