Q3Mesh_FirstContourVertex

You can use the Q3Mesh_FirstContourVertex function to get the first vertex of a mesh contour.

TQ3MeshVertex Q3Mesh_FirstContourVertex (
TQ3MeshContour contour, 
TQ3MeshIterator *iterator);
contour
A mesh contour.
iterator
A pointer to a mesh iterator structure.
DESCRIPTION
The Q3Mesh_FirstContourVertex function returns, as its function result, the first vertex of the mesh contour specified by the contour parameter. The iterator parameter is a pointer to a mesh iterator structure that Q3Mesh_FirstContourVertex fills in before returning. You should pass the address of that structure to the Q3Mesh_NextContourVertex function.
