I'm equally a noob honestly :P** This is a bit over my head but
   ignoring the stuff I don't understand, it makes sense :P

   But yeah - all methods for generating 3D on a screen are
   useful.* Computers are still not that great at rendering lots of
   little voxels; they do a much better job at rendering larger
   things at a time. 3D graphics cards have a unique kind of
   memory.* While on a computer, everything is basically 3D, on a
   video card, the chips can map out a 3D matrix all by themselves;
   basically, voxels. But its easier to connect a line, let's say,
   between two far away spots and draw it, than it is to light up
   individual dots / voxels/etc in a matrix. I think that ray
   tracing is definitely the way to go for most things; its called
   Vector - and I like vector stuff over bitmap stuff. I guess my
   excitement over voxels is that they've been neglected for so
   long.* To me, the natural evolution should've been to go from
   pixels (2D) to voxels (3D) and then to vector stuff.* But the
   voxels got mostly skipped all these years until a few years
   ago.* So i guess that' where my satisfaction is; it's filling in
   a gap.
