One approach to a desktop application which might be "relatively" simple and cross-platform is to use the Qt stuff. In particular, using QtWebKit as a component in a window will give you, pretty much, a full browser which you can get at with C++ code. With the right twiddling, you could use PyQt to grab matplotlib graphics for display. QtWebKit should support JMol and for hard core 3D I would just go full out and nail up Mayavi2. Having the notebook in a window gives you the full notebook editing for free while you build up whatever other editing might be better for a native app. The tricky bit, as usual, is the event loop. Ideally, the application would have access to all the data in a single process. It could support the web stuff and whatever display code which works best native. Building a 3D capability across the wire to replace JMol would be work. I think Mayavi2 is a really significant capability which works great with sage currently and might be a better approach than O3D but I'm not really familiar with that capability. What I currently do, and its a bit of a kludge, is run ipython with the -q4thread event loop. I have C++ Qt windows for my custom gui requirements (invoked through some Cython bridge code), matplotlib through PyQt and Mayavi2. I don't currently use the notebook in those processes because of my use case but twisted is already built into ipython for their parallel computing capability. I've had trouble figuring it out and its sort of a work in progress but the essential capabilities are there. Either way, Qt is a great base because of its web components and its cross-platform architecture. While there are some tricky bits to consider, I think they're "relatively" straightforward and the underlying event loop issue may be easier now with the notebook rewrite activity. > > On Jan 8, 2010, at 2:56 PM, kcrisman wrote: > > > > > > >>> to Mathematica, and Sage, combined with a native front end would be > >>> the trick. > > >> I think you should try.
