Q3Mesh_GetComponentBoundingBox

You can use the Q3Mesh_GetComponentBoundingBox function to determine the bounding box of a component of a mesh.

TQ3Status Q3Mesh_GetComponentBoundingBox (
TQ3GeometryObject mesh, 
TQ3MeshComponent component, 
TQ3BoundingBox *boundingBox);

mesh

A mesh.

component

A mesh component.

boundingBox

On exit, the bounding box of the specified mesh component.

DESCRIPTION

The Q3Mesh_GetComponentBoundingBox function returns, in the boundingBox parameter, the bounding box of the mesh component specified by the mesh and component parameters.

SPECIAL CONSIDERATIONS

The Q3Mesh_GetComponentBoundingBox function might not accurately report the bounding box of a mesh component if called while mesh updating is delayed (that is, after a call to Q3Mesh_DelayUpdates but before the matching call to Q3Mesh_ResumeUpdates).
