i have an elliptic paraboloid equation z=0.5*(x*x+y*y). I generated a set of points (x,y,z). I can draw these points in 2D with the equations:
by ploting (x',z').
i can do the horizontal rotation without any problem, but the vertical rotation is not working, anyone has any idea?

please define horizontal and vertical rotation. We're in 3d, and it's all about the point of view.

Sounds to me like you don't have a clue about spherical coordinates. You know that SAT question about the length of the diagonal of a cube? If you can answer that this should be easy.
i'd be more specific but this sounds like homework

cobra, this thread is almost a month old...I think the OP is gone by now.
