Thread Subject: Implementing a 3D model into Matlab and then operating it (rotation, Euler angles)

Hi,

I would like to write a simulation which solves the Euler-equations (for tops, like the Euler top, Lagrange top, Kovalevskaya top) and then plots the top's motion in 3D. So I would like to be able to implement some 3D model for the top and then be able to rotate it. I would like to apply the rotation to the whole of the 3D object, and I would also require to change the center of rotation of the 3D model. I will only require rotation (and I'll probably use the Euler angles). But I have no idea on how to implement the model, and how to operate it. And I also hope that the animations won't be too slow if I do them in real time. I coudn't find any appropriate tutorial, command or example file, so it would be great if you could point me to that.
