C++ (Cpp) gts_triangles_angle Examples

Example #1

File: coarsen.c Project: NickDaniil/structured

static gdouble cost_angle (GtsEdge * e)
{
  if (e->triangles && e->triangles->next)
    return fabs (gts_triangles_angle (e->triangles->data,
				      e->triangles->next->data));
  return G_MAXDOUBLE;
}

Example #2

File: optimize.c Project: bert/gts

{
    GSList * i;
    GtsTriangle * t1 = NULL, * t2 = NULL;

            else return;
