现代计算机硬件使以以前不可能实现的方式产生视觉刺激成为可能。任意场景，从传统的正弦栅格到自然的3D场景，现在可以在逐帧的基础上实时指定。一个名为Vision Egg的编程库，旨在使利用这些创新变得容易。Vision Egg是一个免费的开放源码库，使用OpenGL，用高级语言Python语言编写，用C扩展。我们仔细关注了亮度和时间校准的问题，并讨论了几种与输入设备(如鼠标、运动跟踪系统和数字触发器)的接口技术。总而言之，这些都使视觉蛋适合于许多心理物理、电生理和行为实验。该软件可在visionegg.org上免费下载。
Modern computer hardware makes it possible to produce visual stimuli in ways not previously possible. Arbitrary scenes, from traditional sinusoidal gratings to naturalistic 3D scenes can now be specified on a frame-by-frame basis in realtime. A programming library called the Vision Egg that aims to make it easy to take advantage of these innovations. The Vision Egg is a free, open-source library making use of OpenGL and written in the high-level language Python with extensions in C. Careful attention has been paid to the issues of luminance and temporal calibration, and several interfacing techniques to input devices such as mice, movement tracking systems, and digital triggers are discussed. Together, these make the Vision Egg suitable for many psychophysical, electrophysiological, and behavioral experiments. This software is available for free download at visionegg.org.
