Q3Mesh_FirstMeshEdge

You can use the Q3Mesh_FirstMeshEdge function to get the first edge in a mesh.

TQ3MeshEdge Q3Mesh_FirstMeshEdge (
TQ3GeometryObject mesh, 
TQ3MeshIterator *iterator);

mesh

A mesh.

iterator

A pointer to a mesh iterator structure.

DESCRIPTION

The Q3Mesh_FirstMeshEdge function returns, as its function result, the first edge in the mesh specified by the mesh parameter. The iterator parameter is a pointer to a mesh iterator structure that Q3Mesh_FirstMeshEdge fills in before returning. You should pass the address of that structure to the Q3Mesh_NextMeshEdge function.
