[quote="spiderman":2s3sxeag]3d models are easier to work with, are supported by hardware and software, and are actually used. Voxels are pretty much useless.
A 3d model is a set of points in 3d space (vertexes) with lines in between. The lines form surfaces, giving shape to the model. Then, an image (texture) is "painted" on the faces of the model to give it a "skin."
A voxel is like a traditional digital image in 3 dimensions instead of two. Picture a Rubik's Cube; It's a 3d object made of a bunch of little cubes in the same way that a digital picture is a 2d object made up of a bunch of little squares (pixels).
Note: the word "voxel" is analogous to the word "pixel;" one voxel is a tiny part of what would make up a "voxel image." However it seems that the word is used to mean both the small voxel unit and the whole voxel image.
Voxel = Volumetric Pixel.
A Voxel mentioned as "small box", is a pixel, but with three information parameters, instead of two, so we can denominate the Voxels as "Pixel with Volume.
To use Voxels is nice, but build them is not so nice. <!-- s:P --><img src="{SMILIES_PATH}/icon_razz.gif" alt=":P" title="Razz" /><!-- s:P -->
