I discussed applications programming and a scripting or back-bone language that is used with it.
what do you infer?
It's a 3D model and I set up a 'camera' and do a 'picture' of a 'scene'. the hello world was made up of duplivert torids that were made of a transparent solid with another inside it that emitts to make the glass material glow like a crystal. I wrote 'hello world' in a flat matrix and it showed up as a three D giant floating sculpture of torids that glow like giant crystal balloons and form the words 'hello world' like a giant neon sign way off in the sky.
duplivert is a method of tiling items. One matrix defines the points at which the other matrix is consequitively reproduced. Using this technique one can get stunning visual effects.
but how would you do it in Fortran on punched cards?
seriously, I tried to give you a hint: get blender and learn python.
