AMD's Developer Relations Chief Richard Huddy demonstrated the abilities of the first DirectX 11 graphics card from the Evergreen series. He is sure that the DX11 graphics cards will be a pleasant surprise when they are released later this year.

3D-Tech News Around The Web / Humus' Particle trimmer updated
« on: July 08, 2009, 12:23:57 PM »
I have made another update to the particle trimmer. Previous revisions produced somewhat inaccurate results since it didn't take texture filtering into account. For most textures it doesn't matter much, but for low-res textures it can be a big deal. In this revision I've added a subpixel precision mode to deal with this problem (default is a 16x16 split of the area between four texels). As a result a lot more points are added to the convex hull and it now pretty much always has to apply the reduction to 50 vertices. If anyone has an idea of how to do the convex hull reduction other than by brute force I'd like to know. I haven't been able to google up any algorithms for that.

I have also made it handle edge and corner cases correctly.

3D-Tech News Around The Web / NVIDIA SLI Profile Patch
« on: July 08, 2009, 12:08:54 PM »
Officially now at NVIDIA.
Make sure you need this one and not that from EVGA, i.e. check the list of supported games.

On June 11th news spread quickly that Maingear CEO Wallace Santos had posted a blog update stating they had received AMDs TWKR CPU. Discussion forums across the net went into overdrive due to the realisation that this was actually an unannounced product. What could it actually be and when would it be available? A few days passed and more information started to leak out and finally we had a soft launch of the TWKR 42 Black Edition last week.

AMD will not be selling this part but is giving a few samples to press, enthusiast users and competition winners. We managed to get hold of a sample for a day’s worth of testing and in this article we will look at what the CPU actually is and how it compares in overclocking to the high end Phenom 2 X4 955 Black Edition.

Some of the key features of the engine are:

- Rudimentary rigid body physics throughout the entire environment
- Deferred lighting with point, directional and spot lights.
- Histogram based HDR and Bloom
- Screen space ambient occlusion
- Atmospheric scattering
- Large procedural planets down to 1.5 meters spatial resolution.

Tops Systems Corp of Japan, a venture involved in multicore technology, together with Toyota Motor Corp and Nihon Unisys Ltd, both of Japan, is developing a dedicated integrated circuit (IC) for ray tracing*, an image rendering method used in 3D computer graphics (3D CG) processing. A total of 73 heterogeneous cores designed specifically for ray tracing operations will be single-chipped, and nine of these chips interconnected (see Fig). With high-definition (HD) resolution at 1920 x 1080 pixels, the target processing speed is 800 tera floating point operations per second (TFLOPS).

3D-Tech News Around The Web / Raytraced Pinball Game
« on: July 06, 2009, 04:23:23 PM »
Time of Light has been developed using the Arauna real-time ray tracer. Using today's CPU technology, real-time ray tracing has now advanced to the point where even a pinball game runs (almost) smooth enough. But you may judge that for yourself: The game is open source, and available here:

The package that you'll find includes source code and the Arauna real-time ray tracer itself.

3D-Tech News Around The Web / YoFrankie 1.1
« on: July 06, 2009, 03:54:45 PM »
Its now 7 months after the DVD release, this is the first version of YoFrankie since being an open project at the blender institute.

Version 1.1 brings YoFrankie up to date with Blender, taking advantage of new features. There have also been improvements in the game logic and levels.

    * Includes the 3 winning levels from the level design competition, with additional improvements.
    * Updated Game Logic for Blender3D 2.49a
    * Runs faster, from testing level 1 home: 2.48a averages 50fps, 2.49a 80fps*
    * Cleaned up blend files, materials, textures, animations, unfinished levels.
    * Loading screen between levels.

Linux 32, 64bit, Windows 32bit (MacOS binary not included but is compatible with 2.49a)

full svn log of changes since 1.0

Of course contributions are still welcome and I intend to keep YoFrankie running with the latest blender, adding levels and content from the community.

* Tested with release builds on 32bit Linux, AMD3800, NVidia 8800.

* Update 1.1a*

    * fixes the secondary level selector (no sign-post) bug.
    * momo dancing in credits was missing.

* Update 1.1b*

    * linux 64bit player was an older blender version.

Codemasters just gave word that the Games for Windows Live version of Colin McRae: Dirt 2 will support the forthcoming DirectX 11.

3D-Tech News Around The Web / 3D Performance with ARMA II DX9 Demo
« on: July 05, 2009, 01:54:17 PM »
ARMA II utilizes Bohemia Interactive’s Real Virtuality 3 game engine. According to Bohemia, RV3 is built on shader model 3, with support for parallax texture mapping, hemispherical lighting, and multi-core CPUs (according to the minimum system requirements, a dual-core CPU and shader model 3.0 GPU are required). The game takes place in a 225 square kilometer area based on real satellite imagery of Eastern Europe and features a realtime day/night cycle with dynamic wind and weather. The game’s physics engine also models real bullet ballistics, material penetration, and round deflection.
