Q3Mesh_GetVertexComponent

You can use the Q3Mesh_GetVertexComponent function to get the component of a mesh to which a vertex belongs.

TQ3Status Q3Mesh_GetVertexComponent (
TQ3GeometryObject mesh, 
TQ3MeshVertex vertex, 
TQ3MeshComponent *component);

mesh

A mesh.

vertex

A mesh vertex.

component

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

DESCRIPTION

The Q3Mesh_GetVertexComponent function returns, in the component parameter, the mesh component that contains the mesh vertex specified by the mesh and vertex parameters.

SPECIAL CONSIDERATIONS

The Q3Mesh_GetVertexComponent function might not accurately report the mesh component that contains a mesh vertex if called while mesh updating is delayed (that is, after a call to Q3Mesh_DelayUpdates but before the matching call to Q3Mesh_ResumeUpdates).
