Q3Mesh_GetVertexIndex
You can use the Q3Mesh_GetVertexIndex function to get the index of a mesh vertex.
TQ3Status Q3Mesh_GetVertexIndex (
TQ3GeometryObject mesh,
TQ3MeshVertex vertex,
unsigned long *index);
mesh
- A mesh.
vertex
- A mesh vertex.
index
- On exit, the index of the specified mesh vertex.
DESCRIPTION
The Q3Mesh_GetVertexIndex function returns, in the index parameter, the index of the mesh vertex specified by the mesh and vertex parameters. A vertex index is a unique integer (between 0 and the total number of vertices in the mesh minus 1) associated with a vertex.
- WARNING
- Vertex indices are volatile and can be changed by functions that alter the topology of a mesh (such as functions that add or delete faces or vertices), and by writing, picking, rendering, or duplicating a mesh, or by calling
Q3Mesh_DelayUpdates. As a result, you should rely on an index returned by Q3Mesh_GetVertexIndex only until you perform one of these operations.8batcolor>s
