The "Pitcher's Duel" project has released SPyRE (Simple Pythonic Rendering Engine) version 0.6. This is a lightweight rendering engine for OpenGL. Provide OpenGL code to draw the model, and the SPyRE engine will display the model in an interface that provides zooming, panning and rotation of camera position using mouse and keyboard. Our goal is to use the engine for a baseball simulation, but it should be generic enough for a variety of applications. Changes in this release include bug fixes to the only reported bug (an initialization problem), and to a glitch in the pivoting code. This release has 'epydoc' documentation, more detailed than the prior docs, and rewritten summary docs. The project includes demos such as a fountain of sparks, a swarming behavior model, a random walk example, a whirlpool effect using gravity and drag, and an example of chaos theory, and a lighted shaded forest scene. The project page is at http://sourceforge.net/projects/pduel/spyre/ To use SPyRE, you also need to have installed Python, OpenGL, pyOpenGL, and PyGame.
