I've posted a patch to http://trac.sagemath.org/sage_trac/ticket/2741 If somebody (Jason Grout -- hint hint) referees it, then it'll be in the next sage release. It makes it so there is a mesh=True and dots=True option for plot3d and parametric_plot3d. The mesh looks pretty good. -- William --~--~-~--~~~---~--~~ To post to this group, send email to sage-support@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-support URLs: http://www.sagemath.org -~--~~~~--~~--~--~---

I wish you would implement it :-) Robert Bradshaw might have some useful advise. Sometimes it is hard to visualize the plot (especially when it is printed) without the mesh lines. If that is easy, what about the possibility of doing some of things that Mma does with different types of meshes?
