Package VisionEgg

The Vision Egg package.

The Vision Egg is a programming library (with demo applications) that
uses standard, inexpensive computer graphics cards to produce visual
stimuli for vision research experiments.

Today's consumer computer graphics cards, thanks to the demands of
computer gamers, are capable of drawing and updating computer graphics
suitable for producing research-quality visual stimuli. The Vision Egg
allows the vision scientist (or anyone else) to program these cards
using OpenGL, the standard in computer graphics
programming. Potentially difficult tasks, such as initializing
graphics, getting precise timing information, controlling stimulus
parameters in real-time, and synchronizing with data acquisition are
greatly eased by routines within the Vision Egg.

See the 'Core' module for the fundamental Vision Egg classes.
