- Clipping? All triangles can't grow above a certain size. That means that you
- don't have to do any clipping; just add some extra space around your visable
- area and there is your clipping...
-
- Our routine (we, the three coders of matrix, mixed our routines in the meantime)
- looks like this:
- Input: pointer to chunky buffer, pointer to list of objects; output: mapped polygons.
- You can guess, that we did some heavy register optimization...
-
- And note: it already works fine!
