Hi, i really need some help to understand, how i can implement Marching Cubes Algorithm into the Voxel Engine i’ve followed this ->guide<- to make.
as far as i understand, these are the fundamentals of the algorithm

if i understand it correctly, edgeTable() is the one that keeps the positions of the verteces, and the triTable() is the one that holds how the triangles are placed inside the cube.
but i really don’t know how to proceed, and but this feature in this code

i really hope that someone will help me.
Thanks in advance.
