4 Traversing Mesh Components, Vertices, Faces, and Edges

4 Q3Mesh_FirstVertexEdge

You can use the Q3Mesh_FirstVertexEdge function to get the first edge around a vertex.

TQ3MeshEdge Q3Mesh_FirstVertexEdge (
TQ3MeshVertex vertex, 
TQ3MeshIterator *iterator);
vertex A mesh vertex.
iterator A pointer to a mesh iterator structure.

DESCRIPTION


The Q3Mesh_FirstVertexEdge function returns, as its function result, the first edge around the vertex specified by the vertex parameter, in a counterclockwise ordering. The iterator parameter is a pointer to a mesh iterator structure that Q3Mesh_FirstVertexEdge fills in before returning. You should pass the address of that structure to the Q3Mesh_NextVertexEdge function.
