Vision Egg project 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.

Perform experiments using an inexpensive PC and standard consumer graphics card
Perform experiments using a graphics workstation if special features needed
Data acquisition and other realtime hardware control capabilities useful in electrophysiology and fMRI experiments, including gaze-contingent stimuli
Dynamically generated stimuli can be changed in realtime via software or external hardware
Produce traditional stimuli to replace legacy systems
Produce stimuli not possible using other hardware
Demo programs to get you started right away
Run stimuli on your laptop - great for talks
Free, open-source software

By harnessing the incredible power of today's consumer graphics cards, producing visual stimuli of research quality now requires no specialized hardware beyond a relatively recent computer and graphics card.

Based on open standards, it runs on anything from cheap PCs to expensive special hardware for special needs. For example, running on some platforms, such as SGI workstations, the Vision Egg has a 10-bit luminance dynamic range (both pixel depth and DAC) and precise frame-by-frame control.

What's New in This Release:
This release comes after 2 years of beta-testing by laboratories around the world.
Since the release of version 0.9.9, major enhancements were made to the ephys server/GUI code to use normal (or slightly modified) demo scripts in this environment.
Numerous bugfixes and small enhancements were done.
