   few questions about rotation around random axis
  Hi, I'm creating a robotsimulation (for the first step with 2 axis) with directx.I load the meshes of the axis seperately and render them. Since the axis are not at the origin, I must first translate them to origin, then rotate and translate them back to their position in order to get the rotations around their own axis. But now come the problems: if I rotate the first axis the rotate the second, it doesn't got the right axis to rotate. http://yfrog.com/2h44925539jsomeone got an idea?thx
  you want to implement a 6dof system... check out This thread for an idea of what you can do.   ;  thanks for your reply, I've read the thread. Just to make sure I understand it right: if I use the D3DXMatrixRotationAxis instead D3DXMatrixRotationYawPitchRoll, does it rotate around an random point instead the origin? Which Parameter should I give(which Vector and Which Angle)?
