There is also a free VRML converter (http://www.mathsource.com/cgi-bin/MathSource/Enhancements/Interfacing/Web/0208-336) and a free program using MathLink and OpenGL (http://www.mathsource.com/cgi-bin/MathSource/Enhancements/Interfacing/Graphics/0209-056) and finally my Java applet (http://theorie3.physik.uni-erlangen.de/~mkraus/Live.html) HOWEVER THIS WAS NOT THE QUESTION! :) As far as I understood, the question was about a possibility to find nice values for the ViewPoint (and ViewCenter) option (by rotating the Graphics3D object). My Java applet can calculate these values, but I do not know whether any of the other programs are able to do so. (The VRML converter and the free MathLink program probably do not offer this service.) In fact this task is nontrivial as soon as you do NOT use BoxRatios->Automatic. (As far as I remember ViewPoint and ViewCenter are even using different coordinate systems.) OK, this was just to clarify the problem and glorify my applet. ;) Martin Kraus
