Q3Mesh_GetFaceNumContours

You can use the Q3Mesh_GetFaceNumContours function to determine the number of contours in a face of a mesh.

TQ3Status Q3Mesh_GetFaceNumContours (
TQ3GeometryObject mesh, 
TQ3MeshFace face, 
unsigned long *numContours);

mesh

A mesh.

face

A mesh face.

numContours

On exit, the number of contours in the specified mesh face.

DESCRIPTION

The Q3Mesh_GetFaceNumContours function returns, in the numContours parameter, the number of contours in the mesh face specified by the mesh and face parameters. A mesh face always contains at least one contour, which defines the face itself. Any additional contours in the face define holes in the face.
