About the Khronos Group

The Khronos Group was founded in January 2000 by a number of leading media-centric companies, including 3Dlabs, ATI, Discreet, Evans & Sutherland, Intel, NVIDIA, SGI and Sun Microsystems, dedicated to creating open standard APIs to enable the authoring and playback of rich media on a wide variety of platforms and devices.
Khronos Today
The Khronos Group is a member-funded industry consortium focused on the creation of open standard APIs to enable the authoring and playback of dynamic media on a wide variety of platforms and devices. All Khronos members are able to contribute to the development of Khronos API specifications, are empowered to vote at various stages before public deployment, and are able to accelerate the delivery of their cutting-edge 3D platforms and applications through early access to specification drafts and conformance tests.

Khronos Media Authoring and Acceleration Standards
OpenGL
OpenGL® is the most widely adopted 2D and 3D graphics API in the industry, bringing thousands of applications to a wide variety of computer platforms. It is window-system and operating-system independent as well as network-transparent. OpenGL enables developers of software for PC, workstation, and supercomputing hardware to create high-performance, visually compelling graphics software applications, in markets such as CAD, content creation, energy, entertainment, game development, manufacturing, medical, and virtual reality. Learn More.
COLLADA
COLLADA™ defines an XML-based schema to make it easy to transport 3D assets between applications - enabling diverse DCC and 3D processing tools be combined into a production pipeline. The intermediate format provides comprehensive encoding of visual scenes Including shaders and physics, and even multiple versions of the same asset. COLLADA FX enables shaders to be authored and packaged using OpenGL Shading Language so that leading 3D authoring tools can work effectively together to create OpenGL / OpenGL ES applications and assets. Learn More.
glFX
An effects framework is critical in the age of programmable graphics as an essential link between DCC tools that create visual effects and applications that need to apply these effects to models and scenes. The glFX specification will create an open standard runtime API for OpenGL and OpenGL ES applications to manipulate and use effects described in the existing COLLADA FX format. The glFX Working Group will also provide documentation, example and utility code, and other infrastructure to enable a complete workflow from content creation through to application rendering. Learn More.
OpenML
OpenML® is an open source, royalty-free, cross-platform programming environment for capturing, transporting, processing, displaying, and synchronizing digital media - including 2D/3D graphics and audio/video streams. OpenML 1.0 defines professional-grade sample-level stream synchronization, OpenGL extensions for accelerated video processing, the MLdc™ professional display control API and the ML™ framework for asynchronous media streaming between applications and processing hardware. Learn More.
OpenGL SC
The open standard OpenGL® SC Safety Critical Profile is defined to meet the unique needs of the safety-critical market for avionics, industrial, military, medical and automotive applications including D0178-B certification. It simplifies safety-critical certification, guarantees repeatability, allows compliance with real-time requirements, and facilitates porting of legacy safety-critical applications. Learn More.
OpenKODE
OpenKODE® is a royalty-free, open standard that combines a set of native APIs to increase source portability for rich media and graphics applications. OpenKODE reduces mobile platform fragmentation by introducing the cross-platform OpenKODE Core API for accessing operating system resources to minimize source changes when porting applications between Linux, Rex/Brew, Symbian, Windows CE, WIPI and RTOS-based platforms. OpenKODE 1.0 also defines an advanced media-stack architecture by bringing together the OpenGL ES and OpenVG media APIs through EGL 1.3 and a set of EGL extensions to provide state-of-the-art acceleration for mixed 3D and vector 2D graphics. Subsequent versions of OpenKODE will use upcoming versions of EGL to integrate synchronization and data processing of streaming media using the OpenSL ES™ and OpenMAX™ media APIs to provide accelerated video and audio functionality that is fully integrated with graphics processing. Learn More.
OpenGL ES
OpenGL® ES is a royalty-free, cross-platform API for full-function 2D and 3D graphics on embedded systems - including consoles, phones, appliances and vehicles. It consists of well-defined subsets of desktop OpenGL, creating a flexible and powerful low-level interface between software and graphics acceleration. OpenGL ES includes profiles for floating-point and fixed-point systems and the EGL™ specification for portably binding to native windowing systems. OpenGL ES 1.X is for fixed function hardware and offers acceleration, image quality and performance. OpenGL ES 2.X enables full programmable 3D graphics. OpenGL SC is tuned for the safety critical market. Learn More.
OpenVG
OpenVG™ is a royalty-free, cross-platform API that provides a low-level hardware acceleration interface for vector graphics libraries such as Flash and SVG. OpenVG is targeted primarily at handheld devices that require portable acceleration of high-quality vector graphics for compelling user interfaces and text on small screen devices - while enabling hardware acceleration to provide fluidly interactive performance at very low power levels. Learn More.
OpenMAX
OpenMAX™ is a royalty-free, cross-platform API that provides comprehensive streaming media codec and application portability by enabling accelerated multimedia components to be developed, integrated and programmed across multiple operating systems and silicon platforms. The OpenMAX API will be shipped with processors to enable library and codec implementers to rapidly and effectively make use of the full acceleration potential of new silicon - regardless of the underlying hardware architecture. Learn More.
OpenSL ES
OpenSL ES™ is a royalty-free, cross-platform, hardware-accelerated audio API tuned for embedded systems. It provides a standardized, high-performance, low-latency method to access audio functionality for developers of native applications on embedded mobile multimedia devices, enabling straightforward cross-platform deployment of hardware and software audio capabilities, reducing implementation effort, and promoting the market for advanced audio.
