3D Theory - Voxel (Volume Pixel)

Two dimensional objects can be scanned in a raster pattern into an array of pixels.

The equivalent can be done in 3 dimensions. This is often used in applications like medical scanners.

There are many ways to code voxel data, for instance:

Volume rendering

DVR (direct volume rendering)

DSR (direct surface rendering)

MIP (maximum intensity projection)

vizmed sites (check out Volrend, Volpack, etc).

surfels" and surfel rendering techniques (effectively floating voxels).
