WebGL Camp at Wallenberg Hall, Stanford University on June 25th 2010, has announced the speaker lineup, and what a lineup it is. Mark Barnes, Biodroid Productions and Work Group Chair for COLLADA will focus on the importance and value of content and how to achieve it with COLLADA. Along with Mark there will be: Peterson Trethewey, O3D; Paul Brunt, GLGE; Giles Thomas, Learning WebGL; Daniel Horn, Sirikata; Daniel B. Miller, Katalabs; Trevor Smith, Spaciblō; Ewen Cheslack-Postava, Stanford Computer Science; Vladimir Vukicevic, Mozilla Firefox; Alan Chaney, Mechnicality and Google Chrome 3D Team.
Erik Rainey has released a series of utilities aimed at making OpenCL easier to use under the Apache 2.0 License. The environment includes: clCompiler which generates both binary outputs and precompiled headers which can be used in conjunction with clEnvironment; clQuery allows you to print all known information about a OpenCL data type. clPid, clYUV and clImgFilter are examples of how to use the utilities to create a compile time kernel make it a dependency in you makefiles and then use the clEnvironment to call your kernel. You can download the OpenCL Environment from github.
The first WebGL Camp is quickly approaching on June 25th, at Stanford University in Palo Alto, California. According to Learning WebGL the following will be speaking at the camp: Vladimir Vukićević, the originator of Canvas3D and WebGL, Trevor Smith of Spaciblo, and Google’s Peterson Trethewey (on O3D and WebGL).
The Khronos Group will be at SIGGRAPH 2010 this year in Los Angeles with their own booth. Visit Khronos at booth # 1201 and pickup a free laminated reference card for OpenCL and OpenGL as well as see some amazing demonstrations from Imagination Technologies, Rightware, HUONE, Vivante and DMP. As well, there will be a number of BOFs this year including the much anticipated OpenGL BOF, COLLADA, OpenCL, Mobile API and new this year, the WebGL BOF. Be sure not to miss out by registering for your spot today. Space is limited so please don't wait til the last minute. Complete details on all the events at SIGGRAPH that Khronos will be a part of are available online.
The Khronos™ Group today announced the ratification and public release of the OpenCL™ 1.1 specification, the latest version of the open, royalty-free standard for cross-platform, parallel programming of modern processors. OpenCL 1.1 adds significant functionality for enhanced parallel programming flexibility, functionality and performance including:
- New data types including 3-component vectors and additional image formats;
- Handling commands from multiple hosts and processing buffers across multiple devices;
- Operations on regions of a buffer including read, write and copy of 1D, 2D or 3D rectangular regions;
- Enhanced use of events to drive and control command execution;
- Additional OpenCL C built-in functions such as integer clamp, shuffle and asynchronous strided copies;
- Improved OpenGL interoperability through efficient sharing of images and buffers by linking OpenCL and OpenGL events.
Differential equations are crucial to all exact sciences, such as engineering, physics, chemistry and even economics. There packages use GPUs to compute solutions to problems such as solving linear systems and computing FFT. This work covers an easy-to-use ordinary differential equation system solver for scientific applications and games. Examples include calculating trajectories and collision of particles in game engines, electron-proton interactions, gravitational calculations, dynamic modeling of deformable bodies and many more.
The Vienna Computing Library (ViennaCL) is a scientific computing library written in C++ and based on OpenCL. It allows simple, high-level access to the vast computing ressources available on parallel architectures such as GPUs and is primarily focused on common linear algebra operations (BLAS level 1 and 2) and the solution of large systems of equations by means of iterative methods.
Learn and share ideas at the Brisbane GPU Users group. Founded to bring together GPU users from all fields and experience levels from southeast Queensland. Topics of discussion include general GPU computing, GPGPU, CUDA, OpenCL, OpenGL, DirectCompute, DirectX and related technologies. The next meetup is tentatively scheduled for June 23rd at GP Library (V Block) Room V714 Queensland University of Technology, from 6pm - 9pm.
JogAmp will be at SIGGRAPH 2010 with their own BOF Session "3D & Multimedia Across Platforms and Devices Using JOGL." This BOF session, on Tuesday, 27 July from 4:00pm to 6:00pm, will discuss the features, contributions, and future of OpenGL, OpenCL, and OpenMax across devices and OS exposed on top of Java using the JogAmp open-source libraries.
Using OpenCL to manipulate OpenGL objects has important advantages: the GPU is usually faster and data transfer from Host memory to Device memory is kept to a minimum. CMSoft OpenCL/GL interop tutorial shows detailed implementation of circular wave interference simulation using CL/GL interop, including commented source code available for download.
