1. i don't see why you would only want to use 1 byte for the x,y,z
coordinates. i doubt that everything in the world that you are
creating would fit into such a small space.
2. if he is only doing wire frame with no clipping of hidden lines, he
does not need to worry about the order of the points (i would think).
but from ordered points, you can determine if the face is towards the
viewer (draw it) or facing away from the viewer (don't draw it) by
calculating the normal.
BTW, can anyone explain to me how to clip lines for a wireframe? for
polygons its easy, just draw back to front, but for lines, how do you
determine if the line is going to be behind another object? you can't
just draw over a line with another line!?!?!?!
for example, how would you draw the lower right corner of box 1 below
with a wireframe?
