4 Traversing Mesh Components, Vertices, Faces, and Edges

4 Q3Mesh_NextFaceVertex

You can use the Q3Mesh_NextFaceVertex function to get the next vertex of a mesh face, in a counterclockwise order.

TQ3MeshVertex Q3Mesh_NextFaceVertex (TQ3MeshIterator *iterator);
iterator A pointer to a mesh iterator structure.

DESCRIPTION


The Q3Mesh_NextFaceVertex function returns, as its function result, the next vertex counterclockwise in the iteration specified by the iterator parameter, which must have been filled in by a previous call to Q3Mesh_FirstFaceVertex or Q3Mesh_NextFaceVertex. If there are no more vertices, this function returns NULL. This function iterates over all the contours in the face.
