------------------------------------------------+--------------------------
 SFCGAL provides a function for a **Constrained Delaunay Triangluation**.
 This is a useful feature for many application scenarios. Currently, it can
 be accessed like this:

 {{{
 CREATE OR REPLACE FUNCTION public.st_triangulate2dz(geometry)
   RETURNS geometry AS
  '$libdir/postgis-2.4', 'sfcgal_triangulate'
   LANGUAGE c IMMUTABLE STRICT
   COST 100;
 }}}

 It would be great to expose this SFCGAL function in PostGIS in the future.

 I created a GIST with some more information and a small testing example
 and some images.
