Dirt 2 has been confirmed to be one of the first games that will use Microsoft's new DirectX 11 API. PC Games Hardware had the chance to interview Bryan Marshall, the Technical Director of the Codemasters development team.

No one has ever shown such a complex demonstration of true interactive GI using a GPU or CPU implementation. 
Why? Because GPUs and CPUs are not architected to fully solve the ray tracing problem efficiently. 
The CausticRT platform addresses these deficiencies and enables GPUs and CPUs to shade with an efficiency comparable to rasterization.

AMD's waited 15 months to introduce a new graphics-card architecture. It arrives in the form of the high-end Radeon HD 5870 and HD 5850 GPUs.

Launched a month before the release of Microsoft's Windows 7 operating system, AMD is hoping to leverage the significant interest generated by the well-received OS and use it to catalyse sales of the next-generation cards.

3D-Tech News Around The Web / Paint.NET v3.5 Beta 1 with DirectWrite support
« on: September 23, 2009, 04:45:03 AM »
Paint.NET v3.5 Beta 1 -  Download, released on September 20, 2009
The first beta of Paint.NET v3.5 is now available! Changes since version 3.36:

    * Refreshed user interface with new icons and visual styling. On Windows 7 and Vista, it is enhanced for Aero and "glass".
    * Now uses and requires .NET 3.5 SP1, which has many built-in performance improvements.
    * New effect: Blurs -> Surface Blur, by Ed Harvey
    * New effect: Distort -> Dents, by Ed Harvey
    * New effect: Distort -> Crystalize, by Ed Harvey
    * Effect dialog responsiveness has been greatly improved.
    * Images open much faster, especially on single CPU systems.
    * Selection outline is no longer animated. Instead of "dancing ants", an antialiased and stippled "XOR" outline is drawn.
    * Startup performance on most systems will be better by about 20%.
    * Memory usage has been greatly reduced when more than one image is open.
    * The font system for the Text tool has been completely rewritten, and problems with missing fonts and crashes should be a thing of the past.
    * On Windows XP and Vista, the Text tool has improved text rendering quality (it uses GDI instead of GDI+).
    * On Windows 7, the Text tool will use DirectWrite (instead of GDI) which gives even better performance and quality.

3D-Tech News Around The Web / Away3D Programming Tutorials
« on: September 23, 2009, 04:39:41 AM »
Matthew Casperson has written a new tutorial series that shows you how to create a 3D Flash game using the Away3D engine.

New 64-bit ready version of PhysX System Software is released. It contains updated .dlls for SDK 2.8.1 and runtimes for new SDK 2.8.3.

Another feature – installation paths are changed now, so all vital libraries and files are stored in “..\Program Files\NVIDIA Corporation\PhysX” folder instead of “..\Program Files\AGEIA Technologies” – this also makes PhysX drivers more compatible with Windows 7 OS.

Yon can download newest PhysX 9.09.0914 driver from PhysXInfo, or just wait until it appears at NVIDIA website.

3D-Tech News Around The Web / Geometry based Anti Aliasing
« on: September 22, 2009, 05:09:59 PM »
Suggesting a technique of implementing a Geometry based Anti Alias(GAA), instead of using the built in 3D graphics AA. This technique has the potential to improve performance and quality of the AA under certain conditions. In short, I am using a geometry based or fins geometry outline technique, and use it to draw translucent smooth edges with the same color of the original 3D model.

The XStream CUDA-enabled technology uses the massively parallel computing capability of the GPU to produce ultra-fast FDTD (finite difference time domain) numerical computations that, says Remcom, provides the capacity to solve EM simulation problems up to 300 times faster than on a 64-bit CPU alone.

In a new Gamasutra feature, part of the Intel Visual Computing microsite, two Intel engineers delve into the technique of ambient animation scaling.

The benefit of such scaling is that it allows meaningful gameplay to stay smoothly consistent across multiple levels of hardware performance, but systematically takes advantage of higher-performance systems by scaling up. Intel's Mike Yi and Orion Granatir demonstrate the technique through the free Horsepower demo, the source code to which is provided.

Kingsoft made extensive use of Intel® Graphics Performance Analyzers (Intel® GPA) to craft their latest release of JX3 Online*, a 3D massively multiplayer online role-playing game (MMORPG). Kingsoft utilized both primary components of Intel® GPA, the System Analyzer and the Frame Analyzer, to identify bottlenecks and slowdowns in graphics processing. With support from Intel, Kingsoft developers determined overall system performance metrics and pinpointed sections of the code where bottlenecks and unnecessary draw calls slowed graphics performance. Using diagnostic techniques and optimization methods suggested by Intel application engineers, Kingsoft successfully boosted the overall playable frame rate for the game performance by 2.1x when run on systems with Intel® 4 Series Express Chipsets graphics.

3D-Tech News Around The Web / NVIDIA claims DirectX 11 is not important
« on: September 17, 2009, 03:46:09 PM »
Nvidia Corp. said during a conference for financial analysts that the emergence of next-generation DirectX 11 application programming interface will not drive sales of graphics cards. The firm believes that general purpose computing on graphics processing units (GPGPU) as well as its proprietary tools and emergence of software taking advantage of these technologies will be a better driver for sales of graphics boards than new demanding video games and high-end cards.

AMD has always been an advocate of open standards that build on and extend proven technologies (example: x86-64)W.  As such, it is a natural fit for AMD to embrace OpenCL as part of its ATI Stream offering.  But, just what is OpenCL?

In this month's episode of the AMD Developer Inside Track I interview Mike Houston, GPG System Architect.  He talks about what OpenCL is, what the transition to this new language will be like and he gets into what applications could benefit from OpenCL, as well as what the future has in store for software applications that use it.   

One of the advantages of OpenCL is its advanced queuing system which is great for game development. It is also designed to work very well with various graphics APIs such as OpenGL, DirectX 9 and DirectX 10.

Game developers aren't the only ones who can take advantage of OpenCL though.  According to Michael, it is going to be very useful for applications such as media encoding, virus scanning, and physics to name a few.  It makes a lot of sense for AMD to move to a ubiquitous computing language that runs on platforms everywhere.  The next few years will be an interesting time for GPGPU technology as several hardware and software vendors get on board.

ATI Stream technology is gaining significant momentum.  Some cool and unexpected examples of ATI Stream technology in action are:

    * Folding@home:
    * Milkyway@home:

An example of gaming technology and OpenCL:

    * Havoc demo:

3D-Tech News Around The Web / Deferred Global Illumination using OpenGL 3.2
« on: September 16, 2009, 11:39:36 PM »
I started new GI renderer, using OpenGL 3.2. I create multiple point lights to simulate GI, and use deferred shading to render them. With nv_explicit_multisample, I have real antialiasing (not edge-blur-filter).
Link to demo: (compatible with 190.57 nvidia drivers).

I've also posted explicit_multisample tutorial:
