3D plot in spherical coordinates [message #233]

I would like solutions to plotting a surface defined in spherical coordinates.
For example, I want to make a plot of the surface z defined by

z = 1. + sin^2(theta)*cos(phi)
where
theta = polar angle
phi = azimuthal angle.

I considered a transformation from spherical to Cartesian coordinates
and then a surface plot, but hidden line removal suffers (see note under
surface in Appendix B of IDL User's Guide). I would like something that
has the verstility of surface, e.g., the arbitrary viewing direction.
