Spline Update
From the feedback I got it seems people aren’t keen on doing things themselves. So I’ve uploaded a full solution:

As always you can access this via an SVN client or by simply using your browser, your choice. I’ve modified things slightly to use a nehe demo that includes arcball rotation for moving your scene around to view the spline. Points are still hardcoded, I’m not going to write you lot an importer. I’ve added a keystroke for switching between Bezier(‘b’) and Catmull-Rom(‘c’) splines. This will give you an idea of how these two curves are different.
It was noted that my implementation doesn’t properly include end points. That is sort of true, to connect to the start and end curve points just double them up. IE, have 2 copies of your start and 2 copies of your end.
As an aside I’d like to thank Makeeva for the wonderful private comment that reads as follows:
“Dont post exampels if you dont have everything there!!! ive spent a hour now and havent gotten it working. you’re program is like you, dumb.”
Allow me to take this moment to apologize for not providing the proper hand holding to go along with my 4:00a.m. post. As proper punishment for my transgression I will hand convert all of my code to assembly before recompiling my next example.
