direction-vector (Re: [ODE] omnidirectional drive (wheels))

yes, this sounds very well. I will try it out...

BTW: do you know a fast way to get the direction-vector from my wheel? (I 
need this for the friction-direction-vector FDir1) I mean, if I create the 
wheel with its axis parallel to the x-axis in the world, and my car moves 
around then. One way would be to get the rotation around z and calculate the 
dir-vector of the wheel (where it is rolling to). But is there maybe a faster 
way?

Thanks!
