3D-Tech News Around The Web / Unity 3 technology – Surface Shaders
« on: July 18, 2010, 07:57:50 AM »

In Unity you can write your own custom shaders, but it’s no secret that writing them is hard, especially when you need shaders that interact with per-pixel lights & shadows.
In Unity 3, that would be even harder because in addition to all the old stuff, your shaders would have to support the new Deferred Lighting renderer. We decided it’s time to make shaders somewhat easier to write.

Warning: a technical post ahead with almost no pictures!

3D-Tech News Around The Web / DDSWithoutD3DX Sample Update

DDSWithoutD3DX Sample Update

Over the past few releases of the DirectX SDK, I've been working on updating our documentation for the DDS file format. The DDSWithoutD3DX  and DDSWithoutD3DX11 samples in the DirectX SDK (June 2010) release demonstrate the details of interpreting the DDS file format for basic 2D textures and 2D texture arrays for Direct3D 9, Direct3D 10.x, and Direct3D 11. Since the June release, I've been expanding the sample to support cubemaps, volume textures, and 1D textures. In the process I also found a number of minor issues with the DDSTextureLoader code and the DDS.H header.

Attached to this post is a ZIP containing an updated DDS.H, DDSTextureLoader.cpp, and DDSTextureLoader.h which you can drop into the DDSWithoutD3DX11 sample code in the DirectX SDK (June 2010). Note that the DDSWithoutD3DX sample is very similiar if you are looking to use it with Direct3D 10.x instead of Direct3D 11, although there are some additional complexities when dealing with cubemap arrays which are supported by the Direct3D 10.1 API with D3D10_FEATURE_LEVEL_10_1 hardware, but not the Direct3D 10.0 API or D3D10_FEATURE_LEVEL_10_0 hardware. A more complete update of both of these samples will be included in a future release of the DirectX SDK.

GPU3 open beta test continuing well

I wanted to post an update on our GPU3 beta test.  It is going well, so we have put the GPU3 client on our high performance client download page. This new client is required for all Fermi hardware, but also allows pre-Fermi NVIDIA GPUs to access the new GPU3 cores.  These cores are labeled core15 (which has already been extensively tested and is in production right now) as well as a new core16 which will be appearing in testing in the coming weeks.

We are also working to finish our OpenCL port for ATI GPUs to support GPU3 on ATI, but there are still performance issues for OpenCL on both NVIDIA and ATI which are holding back this release.  You can see more information about the key software behind the GPU3 cores at the OpenMM project website. If you're curious, there is openCL code there for NVIDIA and ATI and we invite the open source OpenCL community to check out this code and see how they can help if interested (note the code is released under an LGPL license).

ntersect blog: "I’m already looking forward to telling you all about the new Release 260 drivers which are coming in about a month’s time."

NVIDIA drivers forum: "The fix for Gothic I and II is a major driver change which will also fix other DX7 class games. The fix was recently integrated into our Release 260 driver. We will soon be testing a few older DX7 games to verify the changes fix the issue. Hopefully assuming these changes worked, you will see fix in the next web release based on our 260 branch."

Denver, CO USA– July 13th, 2010: Crytek GmbH (“Crytek”) and IllFonic, LLC announced today that IllFonic has licensed CryENGINE 3 for Nexuiz, their upcoming XBLA and PSN cult futuristic Arena First-Person Shooter dropping this Winter. CryENGINE 3 has allowed the IllFonic development team to achieve their vision for Nexuiz that will push the limits of what gamers can expect from an AAA digital downloadable title.

“IllFonic firmly believes in bringing the consumer the highest quality games at an affordable price through downloadable distribution channels”, said Charles Brungardt, President of IllFonic.“Switching to CryENGINE 3 has helped us stay true to our vision and build the Nexuiz arenas the way we see it without any limitations. We are incredibly proud that Nexuiz will be the first downloadable title developed on CryENGINE 3.”

“We’re delighted to have Illfonic join our community of licensees”, said Carl Jones, Director of CryENGINE Global Business Development.“It’s exciting to see a passionate group like Kedhrin and Charles’ team working with CryENGINE 3 on such a cool title. Nexuiz is going to deliver a game style that will be a blast for the console audience, matched with the best graphics possible on the consoles. We’re delighted to offer our engine to teams for XBLA and PSN titles so that gamers can enjoy the quality that CryENGINE 3 can provide, as soon as possible. Our real-time multiplatform pipeline, Live Create, is highly suited to prototyping and delivering quality for games with shorter development cycles; and you get all the benefits of the AAA features of the engine. Nexuiz is going to be a lot of fun and we’re glad Illfonic have chosen CryENGINE 3 to deliver it in style.”

"When we were strolling around GDC 2010's floor we stopped by the Crytek booth. I watched someone show off a few features of CryENGINE 3. Right then and there, I knew I had to have it. It's powerful, fast and easy to use,” said Kedhrin Gonzalez, Creative Director of IllFonic.“Crytek has been awesome to work with providing excellent support in a relationship that has really benefited us."

Nexuiz is a fast paced Arena first-person shooter with competitive game play built specifically for consoles. Featuring the innovative mutator system, players progress through the ranks opening up new mutators that allow players to alter the rules for each match. On launch, Nexuiz will feature multiplayer modes including Team Deathmatch and Capture the Flagcomplete with full competitive leader boards designed for social networking. New games modes, models, and maps will be available as downloadable content post launch.

Nexuiz is set in a galactic war fueled for centuries by the Kavussari and Forsellians. Over time the two races entered into treaties with the Herald Accord, a union between different cultures in the galaxy. Even though peace settled across their planets, the seething hatred between the races kept the fire of war simmering under the fragile truce. Sensing their newest members could spread war throughout the galaxy; the Herald Accord gave the Kavussari and Forsellians a choice. Pit their warriors against each other in the arena rather than on the fields of war, or face total annihilation. The Nexuiz was formed, a series of battle arenas on the home planets of the Kavussari, Forsellian and the desolate planet of Atavirta.

IllFonic will be showcasing Nexuiz using CryENGINE 3 at this year’s PAX Prime in Seattle, WA, on September 3-5.

For more information on Nexuiz, go to www.nexuiz.com or www.illfonic.com.

3D Rotterdam is a collaboration between ESRI, Procedural Inc, and NVIDIA with the goal to develop new techniques for smart 3D city solutions based on GIS data and procedural modeling technology.

The project introduces a new pipeline for the creation, analysis and visualization of photo realistic 3D cities generated from 2D ArcGIS data. Furthermore NVIDIA's RealityServer, which runs in a GPU-based cloud computing environment, enables the sharing and full remote interaction with complex 3D cities on mobile devices such as netbooks, tablets or even the iPhone.
