Voxels

Hey everyone. I’ve been looking around a little about voxels and what they are. It’s been kinda hard to find any tutorials on them. I’ve basically found site about people talking about how their engines support voxel based rendering. From wha ti’ve gathered, you would render cubes over the polygon and the interpolate the color from the texture and apply it to the cube. I was wondering if anyone knew good links to some tutorial like articles on voxels.

Sorry if this is a really basic question on an advanced forum! I didn't know if i should have placed this thread on the beginner forum or the advanced forum. I figured you guys would know more about this stuff so here it is =).

Thanks in advance to all you guys that can help out!
