Hi,
I am new to pov-ray, actually I know absolutely nothing about it! :D

The question is:
I have a curve (x, y pairs, result of a scientific experiment), now
I want to rotate the curve around the y axis. It will make a 3D
surface then, i.e. x'=x*cos(a), y'=x*sin(a), z'=y [a=0~2*Pi].

How to do it in pov-ray?

Thanks
