Khronos Frequently Asked Questions


What is the relationship between SGI and Khronos Group?

SGI is not a member of the Khronos Group. Khronos licenses the OpenGL ES trademark from SGI. Khronos is authorized to run the OpenGL ES adopter program.

Is an OpenGL ES adopter required to comply with OpenGL licensing when they have an OpenGL ES conformant product?


We would like to know what membership will cost to obtain OpenVG and OpenGL, with the exact same type of membership?

The Khronos membership agreement includes a Conformance Test Source License Agreement (CTSLA). Members that have not excluded themselves from the CTSLA, have access to the conformance test source. Members wishing to claim conformance to OpenVG and OpenGL ES specifications would be required to execute the adopters agreement and pay the applicable fee for each API.
