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.
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.
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
