Q3Mesh_GetComponentOrientable

You can use the Q3Mesh_GetComponentOrientable function to determine whether the faces of a component of a mesh can be consistently oriented.

TQ3Status Q3Mesh_GetComponentOrientable (
TQ3GeometryObject mesh, 
TQ3MeshComponent component, 
TQ3Boolean *orientable);
mesh
A mesh.
component
A mesh component.
orientable
On exit, a Boolean value that indicates whether the faces of the specified mesh component can be consistently oriented.
DESCRIPTION
The Q3Mesh_GetComponentOrientable function returns, in the orientable parameter, the value kQ3True if the faces of the mesh component specified by the mesh and component parameters can be consistently oriented; Q3Mesh_GetComponentOrientable returns kQ3False otherwise.

SPECIAL CONSIDERATIONS
The Q3Mesh_GetComponentOrientable function might not accurately report the orientation state 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).
