ZOE A trivial OpenGL rendering engine written entirely in Python ZOE is a trivial OpenGL graphics engine, written entirely in Python. It's primary focus is rapid prototyping and experimentation, so it only supports the barest essentials, with focus on wire frames. Special emphasis is placed on particle systems (where non-interacting particles follow simple rules). Some familiarity with OpenGL is expected, although when exploiting the particle system abstractions no specific OpenGL knowledge is required. Demos included are the obligatory spinning polyhedra, static views of conic sections and the Solar System, a 3D surface plotter, a fountain of sparks, a swarming behavior model, a random walk example, a whirpool effect using gravity and drag, and an example of chaos theory and sensitivity to initial conditions. http://www.alcyone.com/software/zoe/zoe-latest.tar.gz Erik Max Francis 1.0
