I'm curious about Voxatron's renderer, considering it's software-based and does full-on 3D representations of voxels, instead of the point-cloud type of representation. Is it just a basic scanline renderer and is being fed quads/triangles that make up the cubes, or is it some sort of raycasting algorithm?

I only ask because I'm trying to formulate a cross-platform renderer of my own, and Voxatron looks bloody amazing. I appreciate whatever I can get. :)

Thanks in advance!
