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:

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.
