I am having difficulties making anything appear on the screen when I
combine ortho() with polarview(). if instead of ortho() I use
perspective() everything works fine. Specifically, I am trying to view
a cubical array of voxel centered around (0,0,0). For that I do

   ortho(-A, A, -A, A, -A, A); /* A is bigger than the volume's radius */

and then

   perspective(...);

what's wrong ?
