There are as many ways of creating visual stimuli as there are vision experimenters. Here I have listed all current solutions that I know of. If you know of others, let me (astraw@users.sourceforge.net) know.

At a first instance, check out Hans Strasburger's "Software for visual psychophysics" webpage, which has much more coverage than this page. I have here mainly limited listings to projects that appear to be under active development or support.

The PsychToolbox is a great, free program that uses Matlab to display stimuli. Historically it is a Mac OS Classic application, but now a Windows port is available. A native OpenGL Mac OS X version is on its way. (Source code is available but not open source according to the Open Source Initiative.)

PsyScript is a Macintosh program for generating stimuli. Free, open source (GNU Public License). Uses AppleScript and a language based on ECL (experiment control language).

Psyscope (classic Mac OS) users will be pleased to note Psyscope X, is being ported to Mac OS X under the GNU GPL.

Presentation Free (for now) Windows based stimulus generation. Uses DirectX.

WinVis web-based and Matlab based stimulus generation programs.

VSG uses proprietary hardware and software to generate stimuli. It lacks any hardware-accelerated 3D features.

OpenRT and OpenRT-3D OpenGL stimulus generation. Free, open source.

PsychoPy uses python and OpenGL together. Free, open source.

PXLab a collection of Java classes for running psychological experiments. Free.
