Libgls: a library for stereoscopic rendering using OpenGL
The libgls library allows stereoscopic rendering with OpenGL, without requiring hardware support for quad-buffered stereo.
Many stereoscopic display modes are supported, from anaglyph glasses to various types of 3D TVs and stereoscopic displays. Most of the code comes from the Bino 3D video player and thus is already known to work on a wide range of OpenGl implementations. Nevertheless, if you find a problem, please let us know.
Libgls is available under the MIT/X11 license, which means it can be used both in free and proprietary software without problems.
