These demos run only on SGI machines and require the 'gl' built-in module. The demonstrate the abilities of SGI's GL library as well as the ease of GL programming in Python. Most demos require the Z-buffer (aka 24-bitplane) option. Press ESC to get out of any of them. backface.py Demonstrates the 'backface' GL function. kites.py Show 3 flying kites. Demonstrates the rendering speed obtainable by Python programs. kunst.py Cute demo showing a ball suspended on four cables in the central room of the CWI building. You can specify three functions Fx(t), Fy(t), Fz(t) which define the movement of the ball. Try something like sin(t), cos(t), sin(2*t). mclock.py A colorful clock with more options than you can remember. Works on 8-bit machines, but allows more colors on 24-bit machines. See mclock.doc for more info. mixing.py Demonstrates the effect of color mixing: through frequent color switching it gives the effect of white light. nurbs.py A simple demonstration of the 'nurbs' GL functions. Press left mouse button to toggle surface trimming. zrgb.py Displays a 3-D Gouraud-shaded figure which can be moved around with the mouse. glstdwin/ This is quite different: a partial STDWIN emulation using GL! Requires only small changes to Python programs that use STDWIN. Some features not yet implemented, e.g., scroll bars.
