The 4D miniature golf program. This guy has a whole series of videos about what he did to get such speed. He had to figure out how to use the 3D-oriented GPU hardware or his nefarious purposes.

Good for him! It has a lot of visual appeal. (Predictably) I have some suggestions. On a flat course the best view is w,x,z, without the useless up-down y dimension. You can't see the ball or putter but you CAN see the shadows of such objects, which conveniently are 3D. The target hole is 3D.
If the course is not flat then perhaps better is something like w, x, y+z. You combine two dimensions into one. If you have familiar objects like this then I believe the brain can sort it out since it knows what is supposed to be vertical or horizontal. It's hard to say exactly how it would be done without trying it.
