I also tried to extrude the surface, random populate and make the delaunay inside but doesn't work either. Any ideeas of what component should i use? It's kinda urgent....

Hi Razvan-

I'd recommend trying to actually build the delaunay directly using the surface itself.  It looks like you might be using an earlier grasshopper, so here's the screen shot too.

You use the vertices from bounding box on your target surface to generate a base plane, which then becomes the guide for several operations.  You project the edge curves from your surface to this plane, as well as the randomly generated points, and then test for inclusion.  You then intersect these points with the surface using the plane's z vector as a directional input.  Then you offset these points from the surface using the surface normal and a randomly generated value to give the triangular crenelation you're looking for.  You also subdivide your edge curve and add these points to the delaunay triangulation to ensure that your mesh extends around your boundary.  And you use the plane you've constructed as the guide to making your delaunay mesh.  Finally, when you're splitting your triangles out for either being a window or a wall panel, you test for the ratio of the longest to shortest edge...this prevents your glazing from having any faces assigned that are too long.

managed to make it. good ideea with longest and shortest edge. thanks
