VPython is only lightweight conceptually. Boost and C++ are not lightweight, in my book. Again, I could only see it going this way if there was a library that was easy to install (so that VPython became easier to install than it is now), and that doesn't exist right now (not for the three main platforms). All this is just hot air, since I really have nothing to do with how VPython goes. > I also see it as a possible entry point to things like Ogre and > Panda3d, > but that is on a cognitive level, not a technical level. One interesting way would be to have a pure-python (on top of PyOpenGL?) VPython, and a higher performance VPython (maybe on Ogre), similarly to how there are now ElementTree (pure-python XML), cElementTree (higher performance), and lxml (same API as ElementTree, but really a portal to all the XML processing power of libxml and libxslt, i.e., much more powerful *and* higher performance). > As a component to something either high-level and more heavyweight, or > more low-level, I don't see a purpose to it.

No comparison with OpenGL, since VPython (and all the 3D libraries I know of) already build on OpenGL. They add scenegraphs and higher- level APIs, but it's all OpenGL underneath. My dream would be to have a VPython that is as easy to learn as it is now, easier to install than it is now, and capable of growing with you for awhile. But right now that's just a dream. --Dethe Lao-Tse thought XML was verbose but that did not matter because computers will someday learn from poets. --unknown, via Jason Cunliffe _______________________________________________ Edu-sig mailing list [email protected] http://mail.python.org/mailman/listinfo/edu-sig
