Hello there guys.
Does anybody know about voxels?
I have been looking for this topic and i have no a good idea yet.

I read this kind of data can be visualized using povray but i can´t imagine
how.
Any advice?

I found the next data (.cube)....

In the following example the volumetric data is a 40 by 40 by 40 grid, each
voxel is 0.283459 units wide and the volume is aligned with the coordinate
axis. There are three atoms.

0.35999E-05

      :             :             :           :            :            :

        In this case there will be 40 x 40 x 40 floating point values

First you'll have to convert the data to a density (df3) file, the specs 
are in the documentation. Then you use this file in media statement.
