Q3Mesh_GetFaceComponent

You can use the Q3Mesh_GetFaceComponent function to get the component of a mesh to which a face belongs.

TQ3Status Q3Mesh_GetFaceComponent (
TQ3GeometryObject mesh, 
TQ3MeshFace face, 
TQ3MeshComponent *component);

mesh

A mesh.

face

A mesh face.

component

On exit, the mesh component that contains the specified mesh face.

DESCRIPTION

The Q3Mesh_GetFaceComponent function returns, in the component parameter, the mesh component that contains the mesh face specified by the mesh and face parameters.

SPECIAL CONSIDERATIONS

The Q3Mesh_GetFaceComponent function might not accurately report the mesh component that contains a mesh face if called while mesh updating is delayed (that is, after a call to Q3Mesh_DelayUpdates but before the matching call to Q3Mesh_ResumeUpdates).
