Surfaces
surface object and related functions.
A #GtsSurface is defined as a collection of #GtsFace. No topological constraint is imposed: the surface may or may not be manifold, closed or orientable.
When destroying a #GtsSurface, all the faces not used by another surface are also destroyed. This default behaviour can be changed punctually by setting the global variable gts_allow_floating_faces to %TRUE. You must not forget to set this variable back to %FALSE as all the algorithms of GTS assume the default behaviour.
Casts @klass to #GtsSurfaceClass.
@klass: a descendant of #GtsSurfaceClass.
Casts @obj to #GtsSurface.
@obj: a descendant of #GtsSurface.
Evaluates to %TRUE if @obj is a #GtsSurface, %FALSE otherwise.
@obj: a pointer to test.
The surface class. No virtual function is defined.
@parent_class:
@add_face:
@remove_face:
The surface structure derived from #GtsObject.
This structure should only be accessed through the following functions.
