Sage Worksheets are useful for 3d plotting. See the Sage reference manual:


%var u, v fx = (3*(1+sin(v)) + 2*(1-cos(v)/2)*cos(u))*cos(v) fy = (4+2*(1-cos(v)/2)*cos(u))*sin(v) fz = -2*(1-cos(v)/2) * sin(u) parametric_plot3d([fx, fy, fz], (u, 0, 2*pi), (v, 0, 2*pi), color="green", opacity=.7, mesh=1)
