Developed by post-doc Andrew Straw, the Vision Egg is a software library to produce realtime visual
stimuli for vision research experiments using standard graphics
cards and displays. It is a free (open source) cross-platform
programming library that runs on Windows, Linux, and Mac OS X.
Citing from the webpage:
The Vision Egg is a powerful, flexible, and free way to produce
stimuli for vision research experiments.
The Vision Egg is a high level interface between Python and
OpenGL. In addition to methods for automatic generation of traditional
visual stimuli such as sinusoidal gratings and random dot patterns,
it has a number of functions for moving numeric data, images,
movies, text, and 3D objects to and from your video card and
allowing use of some of its features like perspective distortion.
Therefore, it is also useful for anyone wishing to make use
of the features of today's graphics cards.
