Q3Mesh_NextContourFace

You can use the Q3Mesh_NextContourFace function to get the next face surrounding a mesh contour, in a counterclockwise order.

TQ3MeshFace Q3Mesh_NextContourFace (TQ3MeshIterator *iterator);

iterator

A pointer to a mesh iterator structure.

DESCRIPTION

The Q3Mesh_NextContourFace function returns, as its function result, the next face counterclockwise in the iteration specified by the iterator parameter, which must have been filled in by a previous call to Q3Mesh_FirstContourFace or Q3Mesh_NextContourFace. If there are no more faces, this function returns NULL.
