Great news! At last, ATI has fixed the displacement mapping bug. Now you can do vertex texture fetching in your vertex shaders with a Radeon! And GPU Caps Viewer is happy:
More information about vertex displacement mapping here: Vertex Displacement Mapping in GLSL Now Available on Radeon!.
You can grab the Catalyst 8.10 BETA from here: Catalyst 8.10 BETA.
I wonder if ATI will write this bugfix in the release notes… Anyway guys, this new release of Catalyst seems to be a great version…

DevIL (also called OpenIL) seems to re-birth after almost two years of silence. DevIL is back in a new version 1.7.1. Developer’s Image Library (DevIL) is a cross-platform image library utilizing a simple syntax to load, save, convert, manipulate, filter and display a variety of images with ease.

InteliShade is a Visual Studio plugin allowing you to have code outlining and intellisense when editing HLSL code in your projects. InteliShade 3.0 supports Visual Studio 2005 and 2008 and is available as a free download.
Voici la liste des extensions OpenGL supportées par les pilotes Forceware 177.89 WinXP 32 pour une GeForce GTX 280.
Here is the list of OpenGL extensions supported by Forceware 177.89 WinXP 32 drivers for a GeForce GTX 280.
Les ForceWare 177.89 sont les premiers pilotes à offrir le support OpenGL 3.0. Mais pour le moment, ce support n’est pas officiel. Il faut l’activer de manière logiciel grâce à l’utilitaire NVemulate de NVIDIA:
// wglCreateContextAttribsARB prototype. typedef HGLRC (APIENTRYP PFNWGLCREATECONTEXTATTRIBSARBPROC)\ (HDC, HGLRC, const int*); PFNWGLCREATECONTEXTATTRIBSARBPROC wglCreateContextAttribsARB; // Get a pointer on the create context func. wglCreateContextAttribsARB = \ (PFNWGLCREATECONTEXTATTRIBSARBPROC) \ wglGetProcAddress("wglCreateContextAttribsARB"); // Create an OpenGL 3.0 context. HGLRC gl3Ctx = wglCreateContextAttribsARB(dc, 0, NULL); // // Do something with this opengl 3.0 rendering context. // // Delete the context wglDeleteContext( gl3Ctx ); gl3Ctx = NULL;
Ceci étant dit, voilà la liste des nouvelles extensions pour un contexte de rendu OpenGL 2.1 avec support OpenGL 3.0 activé:
That said, here is the list of the new extensions for an OpenGL 2.1 rendering context with OpenGL 3.0 support enabled:

SIGGRAPH 2008: Khronos Group has announced the release of the OpenGL 3.0 API specification and the GLSL 1.30 shading language specification.
The OpenGL working group has defined a set of OpenGL 3.0 extensions that expose potential new functionality for the next version of OpenGL that is targeted for release in less than 12 months, and a set of extensions for OpenGL 2.1 to enable much of the new OpenGL functionality on older hardware.
According to Dr. Jon Peddie of Jon Peddie Research, a leading graphics market analyst based in California, the installed base of graphics hardware that will support OpenGL 3.0 exceeds 60 million units. AMD, Intel and NVIDIA have made major contributions to the design of OpenGL 3.0 and today all three companies announced their intent to provide full implementations within their product families

TG Daily has interviewed Daniel Pohl, an engineer who is making some impressive progress in ray-tracing research, about Intel’s ray-tracing efforts.
Q: What is Larrabee from your perspective. What is the underlying architecture and the programming model?
A: Larrabee was primarily built as a rasterizering processor. Therefore you have support for DirectX and OpenGL. But it will also be a freely programmable x86-architecture. That means you could, for example, write your own rasterizer with your own API, a ray tracer, a voxel renderer or combinations of those. You could also use it for non-graphical applications that benefit from parallelization.
Q: What API is Intel using to showcase ray tracing demos?
A: We wrote our own API. The shading system uses a HLSL-like syntax that allows you also to shoot new rays within a shader. Using that API the programmer has no need to manually multi-thread the rendering and does not need to optimize the shading with SSE as this is done by the shading compiler automatically.

The Khronos Group announced the release of a new COLLADA specification, which includes new features and expanded functionality designed to further broaden the applicability of the 3D digital asset standard.
COLLADA defines an XML-based schema to make it easy to transport 3D assets between applications – enabling diverse 3D authoring and content processing tools be combined into a production pipeline. The intermediate language provides comprehensive encoding of visual scenes including: geometry, shaders and effects, physics, animation, kinematics, and even multiple version representations of the same asset.COLLADA FX enables leading 3D authoring tools to work effectively together to create shader and effects applications and assets to be authored and packaged using OpenGL Shading Language, Cg, CgFX, and DirectX FX.

The PhysX Pack provided by NVIDIA contains a PhysX fluid demo:
The primary purpose of the NVIDIA PhysX Fluid Demo is to illustrate Smooth Particle Hydrodynamics (SPH)-based particle simulation technology accelerated by the NVIDIA GPU.
The pack also contains the Unreal Tournament III PhysX Mod:
The PhysX pack will be publicly available on August 12, 2008. The package consists of a new graphics driver that will enable PhysX on graphics cards equipped with GeForce 8, GeForce 9, and GeForce GTX GPUs, a downloadable PhysX software pack containing free Unreal Tournament 3 maps, the full version of NetDevil’s Warmonger, NVIDIA demos, and a first look at Object Software’s Metal Knight Zero and Nurien Software’s Nurien social-networking service.
