JMOL has some nice capabilities as far as volumetric rendering goes. I've played with it for a day, but in the end wasn't able to get something to work before I ran out of time. Apparently in chemistry, though, there are several formats for representing volumetric data which are rather straightforward (i.e., just list in a 3d grid the values) and JMOL also has a nice algorithm for extracting just the surface data for a particular contour level and efficiently storing that. Also, you might look at doing 2d region plotting. See http://trac.sagemath.org/sage_trac/ticket/2770 for an example start on this. I think it would be *really* cool to have something like Mathematica's RegionPlot and RegionPlot3D: http://reference.wolfram.com/mathematica/ref/RegionPlot.html http://reference.wolfram.com/mathematica/ref/RegionPlot3D.html or a clipping framework like the RegionFunctions provides in Mathematica: http://reference.wolfram.com/mathematica/ref/RegionFunction.html Thanks, Jason --~--~---------~--~----~------------~-------~--~----~ 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://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
