Hello Mathematica UG: I was doing some experiments with this function. In the help there is an example using RegionFunction -> (#6 > 0.95 &). I cannot find this documented anywhere. Is this documented? I think I remember that there are 6 corrds in a spherical coordinate system (or spherical transformation??). If so, is #6 = r cos(theta)? TIA. Regards..Roger
