@jsiehler Thanks! I'm happy to explain. But maybe I need to manage expectations - the code only applies something like a filter to an already amazing picture. So for each triangle it samples a point from the original picture and colors the triangle in the corresponding color. The most coding work went into placing the vertices of the triangles.
@jsiehler The idea for the placement algorithm came from this blogpost: https://generativelandscapes.wordpress.com/2014/08/28/ice-ray-lattice-basic-recursion-example-8-1/
