DMP announces a two day getting start GLSL Programming training course

• Tags:

DMP has announced a new two day getting start GLSL Programming training course on October 8th and 9th 2009. The OpenGL ES roadmap has been tailored to the diverse needs of the embedded industry and contains two tracks with "1.X" and "2.X" specification roadmaps that will evolve in parallel. The 1.X roadmap will continue to be developed for new-generation fixed function 3D accelerators while the 2.X roadmap will enable emerging programmable 3D pipelines.This course introduce the world of programmable pipeline by explaining basic topics of the GLSL(OpenGL Shading Language) which is a core feature of OpenGL ES 2.x and OpenGL 2.x.

OpenCL: Parallel programmers’ new best friend

• Tags:

Apple's Snow Leopard hit the streets friday as the first major OS to support OpenCL. OpenCL, the Open Computing Language, was originally proposed by Apple to support parallel programming on GPUs and handed over to the Khronos Group, the same independent standards organization that manages the OpenGL standard for 3D rendering. Support for OpenCL may start with Snow Leopard but it will go well beyond that. AMD and Nvidia will have OpenCL drivers for their GPUs under Windows and Linux. AMD and Intel will support OpenCL on their CPUs (including Intel's Larrabee). AMD has already shipped its first OpenCL implementation for its Athlon and Opteron processors. For those folks with OpenCL already up and running on their Apple computers under Snow Leopard, there are two benchmark applications out, so you can see just what OpenCL can do for you. Read More

Mogware releases solution

• Tags:

Collada.NET is a reliable and robust solution for reading, manipulating, and saving collada scenes, animations or models in .NET applications including vertex manipulation, texture library access, support for animation keys, and more. The extensible 100% C# COLLADA reader and writer that eliminates the need to marshal in from the COLLADA DOM. While trying to code a 100% C# toolset, it didn’t take long for us to tire with the constant need and complexity of marshaling in from the COLLADA DOM. We scoured the web searching for a .NET solution, preferably in C#, that would enable us to more easily read, write and manipulate data but never found anything we were completely happy with.  We decided to create our own .NET solution in C#.

We’re using our library in our MogBox tool to reprocess complex 3D content as seen in this demo video. Our library made it possible for us to build this strictly C# tool that truly accomplishes some amazing feats reprocessing complex 3D content. We believe in this community and that through sharing technology, the whole can become stronger.  We simply can’t express how much we’ve enjoyed being able to stay in a .net environment without having to marshal anything.  We hope that by releasing our solution, others will be able to get further in their own development efforts more quickly. You can learn more about our solution on our web page.
