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.
Tony Parisi, one of the co-creators of VRML--Virtual Reality Modeling Language--along side Mark Pescue, recently discussed the future of Virtual Worlds. When asked "What conditions should be present that are not today for a serious widespread of virtual worlds in the future?" Tony response was "two things. First, a ubiquitous client. Either Unity, or a Unity competitor; or WebGL (maybe not version 1.0 because it might not have all the features)." The second item is game play within the virtual worlds.
Scientific American interviewed several institutes to discover how they plan on using OpenCL. Read how researchers at Virginia Polytechnic Institute and State University (Virginia Tech) and The National Institutes of Health plan on using OpenCL to further their studies within the small budgets at their disposal.
Andor Salga has posted a good collection of 3D sketches for WebGL. You can view the code beside the WebGL window. The variety of sketches gives one a good sense of what is possible at this stage of WebGL development. A WebGL enable browser is required.
AMD has posted a case study on OpenCL™ Optimization. The article discusses performance optimizations for AMD GPUs and CPUs using as a case study a simple, yet widely used computationally intensive kernel: Diagonal Sparse Matrix Vector Multiplication.
After the tremendous success of the first seven entries to the ShaderX book series, and the upcoming success of the GPU Pro book, we are looking for authors for GPU Pro 2. The upcoming book will cover advanced rendering techniques that run on the DirectX and/or OpenGL run-time or any other run-time with any language available. It will include topics on: Geometry Manipulation; Rendering Techniques; Handheld Devices Programming; Effects in Image Space; Shadows; 3D Engine Design; Graphics Related Tools; Environmental Effects and a dedicated section on mathematics used in graphics programming. Proposals are due by May 17th, 2010. Contact information, an example proposal, writing guidelines and a FAQ can be downloaded here.
GPU Computing, a term coined by Jon Peddie, like most things, was born out of necessity when it was discovered that a cheap PC with a decent graphics card could perform engineering structural analysis for much less money than a workstation. Jem Davies, the self proclaimed god father of technical talent in ARM, does a great job of outlining what the GPU can do today, and where it's going tomorrow with OpenCL, DirectCompute and Augmented Reality.
KitGuru recently interviewed the well known and highly respected AMD employee Terry Makedon. Covering ATI Stream SDK and OpenCL, among other things, Terry gives a peak into the direct AMD is going with these technologies.
Google announced that it has partly scrapped its own browser plug-in project called O3D. Although they will be throwing its full weight behind the 3D Web graphics technology called WebGL, O3D will live on. Google is rebuilding O3D as a library of pre-built software that others can use on top of a WebGL foundation.
Antix releases v1.0 of its free GDK to support publishers, developers and retail channels delivering networked, native games that consumers can copy and share across multiple screens irrespective of screen size, input device, OS, CPU and fields of use including mobile phones, TVs and STBs. The GDK includes the complete toolset required to enable developers to code and produce ATX-formatted games, define DRM rules, and test the games on a PC and presents standard industry APIs OpenKODE®, OpenGL® ES and integrates with Microsoft® Visual Studio®, Eclipse™, or the developer’s own tool chain.
EnergizeGL is the latest in a hand-full of WebGL frameworks that have recently arrived on the scene. EnergizeGL hides all the technical details of programming, enabling you to concentrate on your own project. Complete with lots of examples and demo's, EnergizeGL 0.7a is available for download today.
AMD announced the availability of the ATI Stream Software Development Kit (SDK) v2.1. AMD is showing their full support behind OpenCL with this update which includes support for : OpenCL / OpenGL® interoperability, OpenCL byte addressable stores, OpenCL images, OpenCL extension which support AMD media operations in OpenCL and device fission in OpenCL, along with a host of other additions. AMD also announced the launch of its own OpenCL Zone developer support website.
