For my project for school, I need to be able to find the x, y, and z speeds of an object given rotation around the x, y, and z axis. If it wasn't for the z rotation, it would be quite easy. However, this rotation makes it a lot more complicated and I have had troubles deriving it myself. I would prefer if you explained it (or gave a link, links are good 
) rather than just giving me formulas. Thanks a lot.
edit: just in case it matters, I am using opengl. With this, having all rotations at zero results at zspeed = speed and yspeed = 0 and xspeed =0
