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. -- Fred Knight MIT Lincoln Laboratory 244 Wood Street Lexington, MA 02173
