The region must consist of a single - * loop of half-edges (see mesh.h) oriented CCW. "Monotone" in this - * case means that any vertical line intersects the interior of the - * region in a single interval. - * - * Tessellation consists of adding interior edges (actually pairs of - * half-edges), to split the region into non-overlapping triangles. - * - * __gl_meshTessellateInterior( mesh ) tessellates each region of - * the mesh which is marked "inside" the polygon. Each such region - * must be monotone. - * - * __gl_meshDiscardExterior( mesh ) zaps (ie. sets to NULL) all faces - * which are not marked "inside" the polygon. Since further mesh operations - * on NULL faces are not allowed, the main purpose is to clean up the - * mesh so that exterior loops are not represented in the data structure. - * - * __gl_meshSetWindingNumber( mesh, value, keepOnlyBoundary ) resets the - * winding numbers on all edges so that regions marked "inside" the - * polygon have a winding number of "value", and regions outside - * have a winding number of 0. - * - * If keepOnlyBoundary is TRUE, it also deletes all edges which do not - * separate an interior region from an exterior one. - */ - -int __gl_meshTessellateMonoRegion( GLUface *face ); -int __gl_meshTessellateInterior( GLUmesh *mesh ); -void __gl_meshDiscardExterior( GLUmesh *mesh ); -int __gl_meshSetWindingNumber( GLUmesh *mesh, int value, - GLboolean keepOnlyBoundary ); - -#endif |
