ParametricPlot3D: specific colour AND shading
I determine the colour of a ParametricPlot3D graphic with a Directive RGBColor. The Option Lighting->False is needed for the colour to appear. The problem is the sense of volume is kind of lost, since EdgeForm Directive is also present. I would like to be able to render graphics with both specific colours and shading. A set of different graphics with these Directives and Options is presented together using the command Show. Maybe the Options AmbientLight and Shading have something to do with it. I looked for this thoroughly (at least I think so) in The Mathematica Book and in MathGroup archives, with no success. Thank you very much for any help.
