I've been thinking about working on basic 3D animations for Sage; I haven't yet found an open ticket either. On AskSage, I gave an example showing how to hack the current animation functionality to animate 3D plots:
http://ask.sagemath.org/question/1275/interact-3d-plotpolyhedron?answer=1999#1999 The idea is to make a dummy animation, with the same number of frames that you want, and then *replace* the dummy animation frames with the ones you want to use. When you call ".show()", your dummy animation object will then work out the necessary command for convert and produce a gif animation for you. Marshall: Perhaps you and I (and other interested parties) should discuss how to best implement 3D animations either on sage-devel or on the appropriate ticket. My thinking has been that "animate()" should work for any iterator of objects which can save to an image format. Currently "animate(w)" tries to call "plot()" on the items in w, and I was thinking of just replacing this with a try/except block that would call something like "save(tmp_%08d.png)" instead, and fall back on plot if that fails. Maybe you have more developed ideas though? -Niles On Thursday, May 6, 2010 8:14:06 AM UTC-4, Marshall Hampton wrote: > > I just noticed that saving 3d objects to a file has finally been > fixed: http://trac.sagemath.org/sage_trac/ticket/2872 > That means we are one step closer to handling 3d animations.
