Hello Tommaso, I developed something VERY similar to that algorithm back in 2007 (C++, software rendering), and then again in 2012 (in Java for Android, with GLES). I got some of your issues fixed back then. Ravines, for instance. You might want to take a look: (3-clause BSD): https://github.com/TheFakeMontyOnTheRun/derelict/blob/master/Derelict3D/src/br/odb/derelict/engine/bzk3/android/geometry/GLESRenderer.java https://github.com/TheFakeMontyOnTheRun/derelict/blob/master...

Don't hesitate to get into touch. I will gladly explain anything. I'm not looking for money. I'm just trying to help. I always felt bad for this algorithm to just gather dust. That post of you made my day.
