Hi,
Is there any way to plot two parametric objects
in plot3d as the samer manner as parametric option is used in plot2d ?
For instance, how can i plot the sphere
[SIN(a) COS(b), SIN(a) SIN(b), COS(a)], [a, - %PI, %PI], [b, - %PI, %PI]
and the cilinder
[1+cos(a),sin(a),z],[a,-%PI,%PI],[z,-3,3]
in the same picture in an easy way ?
thanks in advances,
jose cano
