Cool. thanks. For comparison here's how to do that example using Sage's integrated 3d graphics (both in the notebook and on the command line), which we're (me and Robert Bradshaw) are about to release. In each screenshot you can dynamically rotate the graphic around with the mouse. http://sage.math.washington.edu/home/was/tmp/picture_1.png http://sage.math.washington.edu/home/was/tmp/picture_2.png William --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-devel@googlegroups.com To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-devel URLs: http://sage.scipy.org/sage/ and http://modular.math.washington.edu/sage/ -~----------~----~----~----~------~----~------~--~---
