Please visit Khronos at booth #1444 at the Game Developer Conference (GDC), March 2-4, 2011 at the Moscone Center in San Francisco to learn more about COLLADA. Khronos is also running a series of developer university sessions on Thursday, March 3rd, in Room 301 in the South Hall:

  • WebGL at 9AM
  • OpenGL at 10:30AM
  • Demos at 12 noon
  • COLLADA at 1:30PM
  • OpenCL at 3PM
  • Beer and demos at 4:30PM and finally Mobile APIs at 4:50PM.
  • More details about Khronos activities at GDC can be found on our GDC Event page.

Glenn Kasten and Jean-Michael Trivi both with Google, will be introducing you to the Android release 2.3 (Gingerbread) native audio APIs based on the Khronos Group OpenSL ES standard. Starting with a brief history of OpenSL ES and an introduction to the OpenSL ES object / interface model and initialization process, followed by the Android native audio APIs and their relation to standard OpenSL ES. Highlighted by some typical audio needs for game and other interactive apps with example code fragments for each use case. Be sure to make it to this programming tutorial on Tuesday March 1st from 10:00-5:00 in Room 121, North Hall.

Visit the Khronos Group at GDC 2011 in March. We have lots of demos, exciting news, a DevU happening on March 3rd, and free Khronos API laminated reference cards to hand out. Do you want to find out more about WebGL, COLLADA, OpenGL, OpenGL ES or OpenCL? Drop by our booth #1444 in the Moscone Center. Our DevU will be held at the Esplanade level, Room 301. See you there!

Benjamin Nortier from 1011ltd.com is now in possession of a MakerBot Thing-O-Matic 3D Printer. After surveying the 3D modelling software, disappointment settled in, and Benjamin has decided to build a WebGL 3D modelling tool. The tool must be accessible—Open Source, Powerful—using boundary representation (BRep), and Modern—internet-ready with a solid RESTful API. Complete with a sneak peak, and proof of concept, this project is worth following.

The Khronos Group today announced OpenMAX AL, a video and multimedia specification for mobile devices that supports any and all mobile devices, phones and operating systems. Nokia announced support of the standard at launch, with other companies actively developing around the new specification. The full specification and header files are available in the Khronos Registry, as well, a Quick Reference card is available for immediate download.

The Khronos Group today announced OpenSL ES, a new 3D audio specification to bring advanced sound capabilities to any mobile phone or mobile operating system. Companies announcing support of the new standard at launch include Google and SRS. The full specification and header files are available in the Khronos Registry, as well, a Quick Reference card is available for immediate download.

The Khronos Group just wrapped up another DevU, this time in Seoul. Presentations slides from all the sessions are now online. Some of the Khronos APIs covered at this DevU were OpenGL ES, OpenCL, OpenGL, OpenGL SC, OpenVG and OpenMAX and OpenSL ES by AMD, ARM, DMP, DrawElements, HUONE, NVIDIA, Rightware and Samsung and Takumi. A complete schedule of events is available in our event archives.

NVIDIA is proud to announce the immediate availability of OpenGL 4 drivers for Linux as well as OpenGL 4 WHQL-certified drivers for Windows. Additionally, support for eight new extensions is provided:

  • ARB_texture_compression_bptc – provides new texture compression formats for both fixed-point and high dynamic range floating-point texels.
  • EXT_shader_image_load_store - allows GLSL- and assembly-based shaders to load from, store to, and perform atomic read-modify-write operations to texture images.
  • EXT_vertex_attrib_64bit - provides OpenGL shading language support for vertex shader inputs with 64-bit floating-point components and OpenGL API support for specifying the value of those inputs.
  • NV_vertex_attrib_integer_64bit - provides support for specifying vertex attributes with 64-bit integer components, analogous to the 64-bit floating point support added in EXT_vertex_attrib_64bit.
  • NV_gpu_program5 - provides assembly programmability support for new hardware features provided by NVIDIA’s OpenGL 4.0-capable hardware in vertex, fragment, and geometry programs.
  • NV_tesssellation_program5 - provides assembly programmability support for tessellation control and evaluation programs.
  • NV_gpu_shader5 - provides a superset of the features provided in ARB_gpu_shader5 and GLSL 4.00. This includes support for a full set of 8-, 16-, 32-, and 64-bit scalar and vector integer data types, and more. Additionally, it allows patches (as used in tessellation) to be passed on to the geometry shader, used as input to transform feedback, and rasterized as a set of control points.
  • NV_shader_buffer_store – extends the bindless graphics capabilities of the NV_shader_buffer_load extension. This extension provides the ability to store to buffer object memory, and to perform atomic read-modify-write operations, using either GLSL- or assembly-based shaders.

The official feedback thread is available in the OpenGL Discussion Forums. The drivers and extension documentation can be downloaded from http://developer.nvidia.com/object/opengl_driver.html

Introducing the QtOpenCL library, which wraps the OpenCL 1.0 API in a Qt-style API. It takes the pain out of OpenCL initialization, program compilation, and kernel execution. It also provides convenience functions for interfacing to existing Qt facilities such as QImage and QtOpenGL. QtOpenCL is still a work in progress, distributed as a standalone module outside of the normal Qt source repositories.

The Khronos Group announced the release of the OpenGL® 4.0 specification. This is a significant update to the most widely adopted 2D and 3D graphics API, and includes the GLSL 4.00 update to the OpenGL Shading language allowing developers to access the latest generation of GPU acceleration. OpenGL 4.0 further improves the close interoperability with OpenCL™ for accelerating computationally intensive visual applications. Among the new features: two new shader stages that enable the GPU to offload geometry tessellation from the CPU; per-sample fragment shaders and programmable fragment shader input positions; drawing of data generated by OpenGL, or external APIs such as OpenCL, without CPU intervention; shader subroutines for significantly increased programming flexibility; 64-bit double precision floating point shader operations and inputs/outputs for increased rendering accuracy and quality. Khronos has also released an OpenGL 3.3 specification, together with a set of ARB extensions, to enable as much OpenGL 4.0 functionality as possible on previous generation GPU hardware.

Currently in the planning stages of a new open source project, CLyther, is a Python tool similar to Cython. CLyther is a python language extension that makes writing OpenCL code as easy as Python itself. CLyther currently only supports a subset of the Python language definition but adds many new features to OpenCL. CLyther exposes both the OpenCL C library as well as the OpenCL language to python.

Graphic Remedy, a leading provider of advanced solutions for 3D graphics developers, launched gDEBugger CL at Game Developer Conference 2010. gDEBugger CL allows OpenCL™-based application developers to deliver complex parallel computing applications and significantly improve application performance. gDEBugger CL offers advanced debugging, profiling and memory analysis capabilities that reduce development time, accelerate time to market, help deploy the application on multiple platforms and boost application parallel computing performance. gDEBugger CL supports OpenGL-OpenCL interoperability and works together with gDEBugger GL to display, in a single GUI system, both OpenGL’s and OpenCL’s debugging and profiling data.

The Open Toolkit library is an open-source wrapper that allows .Net/Mono applications to use OpenGL¸ OpenAL and OpenCL. This release improves stability under multi-threading scenarios, introduces a new multithreading sample, improves inline (intellisense) and hardcopy (PDF) documentation and fixes a large number of secondary issues. The Open Toolkit can be used on Windows, Linux, Mac OS X, Solaris and *BSD and is especially suitable to rapid development of games, GUIs, virtual reality and scientific visualizations.
