NVIDIA ForceWare 177.89: OpenGL Extensions and OpenGL 3.0 Code Sample

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:

L’activation d’OpenGL 3.0 donne accès à une nouvelle extension WGL_ARB_create_context qui permet de créer un context de rendu OpenGL 3.0. Si vous souhaitez ouvrir la porte d’OpenGL 3.0, voilà le code nécessaire:
Forceware 177.89 are the first drivers to offer the OpenGL 3.0 support. But currently, this support is not official. We have to enable it thanks to NVIDIA’s NVemulate utility:

OpenGL 3.0 activation gives an access to a new extension: WGL_ARB_create_context.
This extension makes it possible to create an OpenGL 3.0 rendering context. If you wish to explore the new world of OpenGL 3.0, here is the necessary code:

// wglCreateContextAttribsARB prototype.
(HDC, HGLRC, const int*);

// Get a pointer on the create context func.
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:

Real Time Realistic Rendering of Nature Scenes

A thesis about real-time realistic rendering of nature scenes with dynamic lighting has been published. This thesis includes all details about real-time grass rendering and about real-time tree rendering with indirect lighting.

You can grab the thesis here: PhD thesis

It’s a pity there is no real-time 3D demo. Screenshots are cool but a real demo is better!

OpenGL 3.0 Specifications Released

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

Ray-tracing the way to go for game developers?

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.

Collada 1.5 Specifications

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.


NVIDIA GeForce PhysX Performances Tests

This is the continuation of the previous post on PhysX Performance with GeForce.

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.

Unity3D has publihed the result of their hardware survey. Unity3D targets the casual gamer and here are some pictures about what is graphics card of the casual gamer:

Casual gamers are really not interested to performance since around 3% of them haven’t graphics drivers… Most of the graphics cards are integrated chipsets (Intel, S3) and the first decent graphics card is the GeForce 8600 with is ranked 15.
