Q3Mesh_NextMeshComponent

You can use the Q3Mesh_NextMeshComponent function to get the next component in a mesh.

TQ3MeshComponent Q3Mesh_NextMeshComponent (
TQ3MeshIterator *iterator);

iterator

A pointer to a mesh iterator structure.

DESCRIPTION

The Q3Mesh_NextMeshComponent function returns, as its function result, the next mesh component in the iteration specified by the iterator parameter, which must have been filled in by a previous call to Q3Mesh_FirstMeshComponent or Q3Mesh_NextMeshComponent. If there are no more mesh components, this function returns NULL.

SPECIAL CONSIDERATIONS

The Q3Mesh_NextMeshComponent function might not accurately report the next mesh component in a mesh if called while mesh updating is delayed (that is, after a call to Q3Mesh_DelayUpdates but before the matching call to Q3Mesh_ResumeUpdates).
