4 Traversing Mesh Components, Vertices, Faces, and Edges
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.
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.
