Q3Mesh_GetOrientable
function to determine whether the faces of a mesh can be consistently oriented.
TQ3Status Q3Mesh_GetOrientable ( TQ3GeometryObject mesh, TQ3Boolean *orientable);mesh
A mesh.orientable
On exit, a Boolean value that indicates whether the faces of the specified mesh can be consistently oriented.
Q3Mesh_GetOrientable
function returns, in the orientable
parameter, the value kQ3True
if the faces of the mesh specified by the mesh
parameter can be consistently oriented; Q3Mesh_GetOrientable
returns kQ3False
otherwise. For example, the faces of a tessellated Möbius strip or a Klein bottle cannot be consistently oriented.Q3Mesh_GetOrientable
function might not accurately report the orientation state of 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
).
