The Khronos Group is an American non-profit member-funded industry consortium based in Beaverton, Oregon, focused on the creation of open standard, royalty-free application programming interfaces (APIs) for authoring and accelerated playback of dynamic media on a wide variety of platforms and devices. Khronos members may contribute to the development of Khronos API specifications, vote at various stages before public deployment, and accelerate delivery of their platforms and applications through early access to specification drafts and conformance tests.

On 31 July 2006, it was announced at SIGGRAPH that control of the OpenGL specification would be passed to the group.[1][2]

The Khronos Group was founded in 2000 by companies including ATI Technologies, Discreet, Evans & Sutherland, Intel Corporation, NVIDIA, Silicon Graphics (SGI), and Sun Microsystems. It now has roughly 100 member companies, over 30 adopters, and 24 conforming members.[3] Its president is Neil Trevett.

Working Groups

  • COLLADA, a file-format intended to facilitate interchange of 3D assets.
  • EGL, an interface between Khronos rendering APIs such as OpenGL ES or OpenVG and the underlying native platform window system[4]
  • OpenCL, a cross-platform computation API.[5]
  • OpenGL, a cross-platform computer graphics API
  • OpenGL ES, a derivative of OpenGL for use on mobile and embedded systems, such as cell phones, portable gaming devices, and more
  • OpenGL SC, a safety critical profile of OpenGL ES designed to meet the needs of the safety-critical market
  • OpenKCam, Advanced Camera Control API
  • OpenKODE, an API for providing abstracted, portable access to operating system resources such as file systems, networks and math libraries
  • OpenMAX, a layered set of three programming interfaces of various abstraction levels, providing access to multimedia functionality
  • OpenML, an API for capturing, transporting, processing, displaying, and synchronizing digital media
  • OpenSL ES, an audio API tuned for embedded systems, standardizing access to features such as 3D positional audio and MIDI playback
  • OpenVG, an API for accelerating processing of 2D vector graphics.
  • OpenVX, Hardware acceleration API for Computer Vision applications and libraries
  • OpenWF, APIs for 2D graphics composition and display control
  • SPIR, a intermediate compiler target for OpenCL and Vulkan
  • StreamInput, an API for consistently handling input devices.
  • Vulkan, a low-overhead computer graphics API
  • WebCL, a JavaScript binding to OpenCL within a browser.
  • WebGL, a JavaScript binding to OpenGL ES within a browser on any platform supporting the OpenGL or OpenGL ES graphics standards


Khronos group divides its members followingly:[6]

  • Academic Contributors – have full API working group participation but no voting rights.
  • Contributors – have full API working group participation and voting rights, and generous marketing benefits.
  • Promoters – act as the "Board of Directors" to set the direction of the Group, with final specification ratification voting rights.

Current members (as of 27 October 2014) are (highlights):
