Voxel triangulation, using simple greedy algorithm.

Sometimes you need to triangulate, this time it is bescause we want this solution to run on lower end hardware, Where ray marching might not be fast enough.
Warning i think his code is a bit complex, so i made it from scratch and its work ok. But there is always room for improvement.
Just as i uploading this video i found this reference as well.

There is also some basic pr vertex ambient occlusion.
