I am trying to animate two variables in a 3D plot. Basically I would like to combine these two animations into one simultaneous animation:

animate(plot3d, [[y, x, (1/3)*Pi], x = 0 .. 2*Pi, y = 0 .. R, coords = spherical, scaling = constrained], R = 0 .. 5)

and

animate(plot3d, [[y, x, (1/3)*Pi], x = 0 .. p, y = 0 .. 5, coords = spherical, scaling = constrained], p = 0 .. 2*Pi)

so that both animations start and end simultaneously. Is this possible?

Thanks in advance.

I have Imported a CAD model (.sty) into maple. What I want to do is rotate the model along several axes. At first I want to rotate it around its center. This can be done via 

rotate(Zylinder, 2, 3, 56)

where Zylinder is the Object I importet via

Zylinder := Import("C:/...")

this works fine, but I want the rotation to be a continuous animation. I tried:

animate(rotate(Zylinder, A, 0, 0), A = 0 .. 360)

but that does not work. Can you please tell me how to make it work? And it would be great if the aproach would work for rotations around an axis away from the center, too.

I want to plot a function f(x,y)=x^3-2x^2y. But I only want to plot values where $x^2+y^2 <= 1$. So far I specified the plotting range in the standard way, but I really need to specify it like I described. I want to use plot3d.
