Can a torus be represented as a parametric equation? If so, does anyone have the definition? Bob Zigon : :

Each point on the torus can be defined by two angles. Let r be the radius of the cross-section of the torus and R be the radius of the torus. I will assume that the torus lies in the x-y plane. The parametric equation is then: x(a,b) = cos(a)(R+cos(b)r) y(a,b) = sin(a)(R+cos(b)r) z(a,b) = sin(b)r with a and b in the range [0,2\pi) --------- Jos
