GLOS (Graphic Library in Open Source) is a from-scratch software implementation of OpenGL. It currently works with CMUCL, and has not been (and will probably not be) tested on other systems. Textures are not supported.

GLOS was developed by Jonathan Bailleul, Fabrice Bazzaro, Benoit Degand, Renaud-Rolland Hubert and Michael Pujos for a Masters Thesis, and is distributed under the terms of the GPL. The project site is hosted at SourceForge. This site is being reconstructed right now, so please refer to this one during transition.
