OpenGL is a portable, cross-platform software library, often used as an interface to graphics hardware. OpenGL depends on the use of a native windowing system for display. OpenGL can be used to create 2D and 3D graphics, as well as general matrix math processing. OpenGL supports programming techniques such as 3D modeling, lighting, affine transforations, alpha blending, texture mapping, and fog.

OpenGL 3D engines
OpenGl add-on libraries are libraries that work with and depend on OpenGL.
OpenGL Benchmarks provide a way to measure either how good a particular OpenGL software implementation is, or measure how good the underlying hardware running OpenGL is.
Here you'll find link relating to OpenGL books. Including online versions, if available.

This category is for Mailing Lists about OpenGL.
Open source software
Submit here only open source full software providing OpenGL source code
Versions of OpenGL API-compliant hardware, regardless of operating system or windowing system
Submit here only specific implementations of OpenGL
This category is for Software that makes use of OpenGL and which makes the source code available. All of the software in this category is open source so they can be used for education. In other words... use the source.
Do not submit links that do not pertain to software that is not based on OpenGL and open source.
Developer and user tools for OpenGL configuration, management or troubleshooting.
