Re: Drawing transparent objects.
Hi, Mathematica does not support transparence for PostScript (only PostScript level 3 does this). The only solution is to switch to MathGL3d http://phong.informatik.uni-leipzig.de/~kuska/mathgl3dv3/ and use the MVAlpha option of the MVShow3D command. To get really good renderings of transparent surfaces you should export the 3d opbjects form MathgL3d to POVRay or RenderMen and add some refraction. The reason for that is, the human eye expect refraction on transparent surfaces but OpenGL can't do that. Contact me, if you have problems/questions with transparence in MathGL3d.
