Voxels

[DarkOne]

I'd like to create a simple voxel engine. I have been looking for a beginner's tutorial, but have found nothing.

I understand that a voxel is basically a cube polygon. So is it efficient to render voxels as cubed polys, or is there a quicker/better way?


Please help

What is inefficient is drawing all the hidden cubes.
Otherwise voxel engines have historically been built on top of lots of hack and optimizations, even if recently brute force is almost sufficient.
