Well, without a rebuild I tried running an offscreen script via an ssh-session and no login with my existing framework build (i.e. not on Sage). It fails to run since console access is needed. So, for pure offscreen work an X11 build will be necessary. This is entirely similar to the situation on Linux. With mesa you don't get the best hardware acceleration but get pure offscreen. But with hardware acceleration you still seem to need to create a window. So it looks like there have to be two separate packages, one with offscreen+X11 and the other as a framework build for the UI. The framework build approach is easy to do. The X11 approach seems to require patching VTK as the visit developers have done. Would this work? My guess is that this should be acceptable if we make it easy enough to do as two separate spkgs. Only the VTK package would need to be changed to enable one or the other. > Not being able to use a gui, well, I think the notebook is the gui. > But for some projects I also want to use a desktop gui, with mayavi, > so it seems the only way to do so in a multiplatform way is to use > frameworks on Mac. Yes but with the caveat as above. cheers, prabhu --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-devel@googlegroups.com To unsubscribe from this group, send email to sage-devel-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
