I'm having trouble with RGL:
> parametric3d(fx = function(u, v) u * exp(-0.5 * (u^2 + v^2 -
+ 2 * 0.75 * u * v)/sqrt(1-.75^2))^(1/3),
+ fy = function(u, v) v * exp(-0.5 * (u^2 + v^2 -
+ 2 * 0.75 * u * v)/sqrt(1-.75^2))^(1/3),
+ fz = function(u, v) exp(-0.5 * (u^2 + v^2 - 2 * 0.75 * u *
+ v)/sqrt(1-.75^2))^(1/3),
+ umin = -20, umax = 20, vmin = -20, vmax = 20,
+ n = 100)
