Which makes it as easy to install on OS X as on Windows. Building it from source can be troublesome, but is far more tractable in my experience than VPython.

PyOpenGL provides contexts for PyGame, for wx, and others (don't remember the whole list off-hand). If VPython (or VPython-lite) were built on PyOpenGL it would inherit all of these abilities. > And since much of the cross-platform complexity of vpython is on the > windowing context issue, I see that solving that issue for vpython > is a > more direct approach to solving the problem.

A binary installer for VPython could simply make sure the necessary dependencies are installed. A setuptools-based build chain could do the same. > Togl across platforms???

Since that is exactly what GLUT provides, and GLUT is available for every port of OpenGL that I'm aware of, I don't even know where to begin with such a comment. The other issue with VPython portability is threading. Instead of using Posix threads on Linux (which would *just work* on OS X), they pull in the gnome libraries for threading, adding an unneccesary dependency (in my opinion). GLUT alone doesn't really help with that, but it could be a (huge) step in the right direction. --Dethe "Why is Virtual Reality always posited in terms of space, when time is the only real commodity left?" --Rich Gold _______________________________________________ Edu-sig mailing list [email protected] http://mail.python.org/mailman/listinfo/edu-sig
