comment Fitting a 3d point cloud with a polynomial surface
yup, not at the moment. I can try different variants to see what fits. But I am not clear with the process it is easy to conceptualize in 2D but in 3D and with a surface its a bit weird to me.

comment Fitting a 3d point cloud with a polynomial surface
yup in the least square sense. The model could be anything which minimizes the distance of points to the surface. But the least complex model is definitely preferred. Is there a way to determine the model complexity depending on the data?

comment how to rotate a Gaussian?
@Michael, Thanks, you are absolutely right... I just wanted to put a simple function and the constant does not matter that much... What I want to exactly how to get a closed form expression of a function after the rotation... +1 for pointing it out.
