Q3Mesh_GetFaceIndex
function to get the index of a mesh face.
TQ3Status Q3Mesh_GetFaceIndex ( TQ3GeometryObject mesh, TQ3MeshFace face, unsigned long *index);mesh
A mesh.face
A mesh face.index
On exit, the index of the specified mesh face.
Q3Mesh_GetFaceIndex
function returns, in the index
parameter, the index of the mesh face specified by the mesh
and face
parameters. A face index is a unique integer (between 0 and the total number of faces in the mesh minus 1) associated with a face.
Face 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_GetFaceIndex
only until you perform one of these operations.<8batcolor>s
