StreamInput creating open standard for advanced sensor processing; WebCL defining companion API to WebGL to bring parallel computation to the Web

August 8th, 2011 – Vancouver, SIGGRAPH 2011 – In its 10th year of operation the Khronos™ Group today widened its call for participation in its two newest working groups: StreamInput™ and WebCL™.  StreamInput is defining a cross-platform API for advanced sensor processing and user interaction, and WebCL is creating JavaScript bindings to OpenCL™ to enable heterogeneous parallel computing in HTML5 Web browsers.  Any interested company is welcome to join Khronos to make contributions, influence the direction of specifications and gain early access to draft standards before public release for any Khronos working group.  More details on joining Khronos can be found at http://www.khronos.org/members/ or by emailing .(JavaScript must be enabled to view this email address).

The Khronos StreamInput working group is driving industry consensus to create a cross-platform API to enable applications to discover and use new generation sensors to create sophisticated user interactions.  The new API will support a general-purpose framework for consistently handling advanced sensors such as depth cameras, touch screens and motion and orientation sensors as well as traditional input devices.  StreamInput will provide flexible device discovery to enable an application to select and process high-level semantic input from low-level device capabilities, enabling significant innovations by sensor and device manufacturers while simplifying portable application development. The API will also provide system-wide sensor synchronization for advanced multi-sensor applications such as augmented reality, and will use Khronos’ proven extension mechanisms to enable new types of input devices to be easily added and supported.  More information on StreamInput is here: http://www.khronos.org/streaminput/.

The WebCL working group is working to define a JavaScript binding to the Khronos OpenCL standard for heterogeneous parallel computing.  WebCL will enable Web applications to harness GPU and multi-core CPU parallel processing from within a Web browser, enabling significant acceleration of applications such as image and video processing and advanced physics for WebGL games.  WebCL is being developed in close cooperation with the Web community and has the potential to extend the capabilities of HTML5 browsers to accelerate computationally intensive and rich visual computing applications.  More information about WebCL, including links to prototype open source implementations from Nokia and Samsung, is here: http://www.khronos.org/webcl/.

“Advances in computational power on a wide range of platforms and devices are greatly accelerating sensor innovation from 9-axis motion positional sensors, to depth ranging cameras.  StreamInput will drive the market adoption of advanced sensors by enabling input fusion innovation under a common API that provides portability to application developers,” said Neil Trevett, president of Khronos and vice president of mobile content at NVIDIA. “WebCL is the natural extension of the WebGL and OpenCL work already underway at Khronos and continues the trend of evolving HTML5 not only to support advanced Web experiences but also to become a full-fledged application platform with access to advanced device capabilities.”

“AMD is highly supportive of the WebCL initiative to deliver compute capabilities to Web browsing,” said Suki Samra, Senior Director, Design Engineering (NYSE: AMD). “AMD strongly supports industry standards, and as a leading provider of OpenCL and OpenGL solutions on AMD’s GPUs and APUs believes that WebCL will be a welcome companion to the newly released WebGL standard.”

“We are delighted the Nokia initiative to standardize WebCL has been accepted by Khronos. The developer feedback about our WebCL prototype for Firefox has been positive, and we are committed to work with the open-source community to align it with the developing WebCL standard “, says Jyri Huopaniemi, director, media technologies, Nokia Research Center.

“SoftKinetic is excited to contribute to this standard initiative which will facilitate the adoption of new input devices such as depth sensing cameras.  It is important to facilitate content developer’s workflow as much as possible by abstracting these devices behind a robust and standard API", said Erik Krzeslo, chief strategy officer. "SoftKinetic products will greatly benefit from all what Stream Input offers in terms of simplicity, portability and cross-sensors interactions.”

Khronos Enriches Cross-Platform 3D Graphics with 
Release of OpenGL 4.2 Specification

New open API specification available immediately; Developer feedback integrated into wide-ranging performance and functionality enhancements

August 8th, 2011 – Vancouver, SIGGRAPH 2011 – The Khronos™ Group today announced the immediate release of the OpenGL® 4.2 specification, bringing the very latest graphics functionality to the most advanced and widely adopted cross-platform 2D and 3D graphics API (application programming interface).  OpenGL 4.2 integrates developer feedback and continues the rapid evolution of this royalty-free specification while maintaining full backwards compatibility - enabling applications to incrementally use new features, while portably accessing state-of-the-art graphics processing unit (GPU) functionality across diverse operating systems and platforms.

The OpenGL 4.2 specification has been defined by the OpenGL ARB (Architecture Review Board) working group at Khronos, and includes the GLSL 4.20 update to the OpenGL Shading Language.  The OpenGL 4.2 specification contains new features that extend functionality available to developers and enables increased application performance.  The full specification is available for immediate download at http://www.opengl.org/registry.

New functionality in the OpenGL 4.2 specification includes:

     
  • enabling shaders with atomic counters and load/store/atomic read-modify-write operations to a single level of a texture.  These capabilities can be combined, for example, to maintain a counter at each pixel in a buffer object for single-rendering-pass order-independent transparency;
  •  
  • capturing GPU-tessellated geometry and drawing multiple instances of the result of a transform feedback to enable complex objects to be efficiently repositioned and replicated;
  •  
  • modifying an arbitrary subset of a compressed texture, without having to re-download the whole texture to the GPU for significant performance improvements;
  •  
  • packing multiple 8 and 16 bit values into a single 32-bit value for efficient shader processing with significantly reduced  memory storage and bandwidth, especially useful when transferring data between shader stages.

“OpenGL 4.2 has integrated feedback from developers that are shipping significant OpenGL-based applications and games, making for a faster, more capable API which will continue to evolve to meet market needs,” said Barthold Lichtenbelt, working group chair of the OpenGL ARB and director of Tegra graphics at NVIDIA. “As with previous OpenGL releases NVIDIA is committed to ship productized implementations as rapidly as possible after specification release. In fact, NVIDIA released production OpenGL 4.2 drivers today, enabling developers to immediately leverage this new functionality on NVIDIA GPUs.” (Note: for more information, please visit http://developer.nvidia.com/opengl).
 
“AMD plans to release our OpenGL 4.2 beta drivers with the publication of the OpenGL 4.2 specification,” said Ben Bar-Haim, corporate vice president, AMD Software Development (NYSE: AMD). “AMD strongly supports industry standards and congratulates the Khronos Group on their success in the rapid evolution of OpenGL and its other open standards that enable brilliant computing experiences.”
