The OpenGL API (Application Programming Interface) began as an initiative by SGI to create a single, vendor-independent API for the development of 2D and 3D graphics applications.

Modifications to the OpenGL API are made through the OpenGL Architecture Review Board (ARB), an industry group that contains founding, permanent, and auxiliary members.

Software developers do not need to license OpenGL to use it in their applications. They can simply link to a library provided by a hardware vendor.

Hardware vendors do need to have a license to create an OpenGL implementation for their hardware.

The following are the currently available licenses:

  • Open source license - for use of the S.I. This is a Free Software License B closely modeled on BSD, X, and Mozilla licenses.
  • Trademark License - for new licensees who want to use the OpenGL trademark and logo and claim conformance.
