No, I think you don't understand me. You have taken two completely different and unrelated topics and tried to make them somehow related.
You. Are. Not. Making. Sense!

I'm hardly suprised that you don't understand Butch. But I think most everyone else did, even without me beating the point into the ground.

I work with CT Scanners at work, here's what I know about Voxels:
1>The CT scanner aquires sectional images (Slices). It identifies voxels by looking at the CT numbers in the slices. bone, soft tissue and fat have diffrent CT numbers. (I find it easyer to think of the CT number as Density, Air is CT=0 bone is CT=30 (or so))
2>After you get scanned, all the data that makes up your vertebrae could be represented by voxels. For example one vertebrae's data equals one voxel.
The book I have goes on to talk about: Surface rendering, Volume rendering, Preprocessing, Intensity Projection Rendering, and Virtual CT Endoscopy.
So yes a Voxel can be a square of data, but it could also be a blob of data.

Voxel-based processing "makes determinations about each voxel and decides to what degree each should contribute to the final 3D display."
Whereas Object-based processing "uses voxel information to transform the images into a collection of objects with subsequent processing concentrating on the display of the objects."

You guys are thinking too small.
I would think of a cave in mine craft as a Voxel, Each cave is a Voxel. Thats hundreds of data points represented by one thing - a Voxel -
The Minecraft blocks are probably rendered as polygons. <-- needs citetation

Ouch, that hurt. Come back to me when you know what you're talking about. I don't see anyone else backing your nonsense up.
