Thanks for all the help on my previous questions. This one's a bit more complicated, but I'm advancing very fast with this engine which I like.
I want to rotate a ball according to its angular velocity. How do I go about rotating the ball per frame from its current rotation to the next when I have it's angular velocity as a 3d vector?

This sounds similar to what you are trying to do, irrlamb http://irrlicht.sourceforge.net/forum/v ... =5&t=25063 he has the source a few posts down.
What kind of libraries do you use in combination with irrlicht?

Thanks, ill check it out.
I only use irrlicht and irrklang, and the standard c++ libraries. There's not enough physics for me to add a physics library, and I'd like to do everything myself as far as I can.
