3D-Tech News Around The Web / Bethesda's RAGE: megatexture crazyness
« on: July 05, 2010, 04:58:31 PM »
RAGE “Wall”papers now available

Have you been thinking about redecorating your jet airplane? Need to paint your barn, but tired of those dull stripes and solids? Looking for a unique way to drive away those pesky neighbors? We may have the solution for you.

As you can see above, the MegaTexture technology behind RAGE’s visuals lends itself well to high-resolution composites. Three such images were recently used to create massive wall-sized displays for our booth at E3.

However, rather than keep these impressive images to ourselves, we’re now releasing them for mass consumption. Each of the three murals has been converted into standard-sized wallpapers, in 25 resolutions covering PCs, dual-monitor setups, iPads and iPhones.

But wait, there’s more. In addition to those versions, we’re also offering the original, uncompressed, 280mb+, 25K resolution images. That’s a lot of image, and it’s all free to you, the fan. So get downloading:

Dead City Desktops ZIP (25 resolutions, 13.3mb)
Mutants Desktops ZIP (25 resolutions, 5.5mb)
Wasteland Desktops ZIP (25 resolutions, 5.5mb)

Dead City TIF (25,600×9,080 resolution, 282mb)
Mutants TIF (25,600×16,000 resolution, 363mb)
Wasteland TIF (25,600×16,000 resolution, 324mb)

Oscar analyzes the features of Stream SDK 2.2 and 2.3

Also he points to the talk about "Addition of early version of GPU support for cloth/softbody simulation" in Bullet.
2 CPU cores hogged and 40% GPU usage - that's why it reads "early version" i assume...

The latest released version of VLC, 1.1.0, that was out a week ago, and has been downloaded half-a-dozen millions times so far, has added GPU acceleration for HD decoding under Linux and Windows. On Windows, as already stated, the code isn't working correctly with AMD Radeon cards.
Therefore, we have been working with AMD on this topic and after common work, we are going to release a new version of VLC, versionned as 1.1.1, that will work with the upcoming ATI Catalyst 10.7 driver. AMD did provide us a beta of this driver and we have verified successfully that GPU acceleration works.

Changes between 1.1.0 and 1.1.1:
--------------------------------

libVLC:
 * Support for the new capabilities: libvlc_adjust_Enable, libvlc_adjust_Contrast,
   libvlc_adjust_Brightness, libvlc_adjust_Hue, libvlc_adjust_Saturation, libvlc_adjust_Gamma
 * Various fixes and crash preventions, especially when video functions were called early

Stream output:
 * Fix h264 streaming in ts

Windows and Mac port:
 * Fix mod files support

Decoders:
 * Fix performance issues with GPU decoding using DxVA2 using ATI graphic cards
   You NEED ATI Catalyst 10.7

MacOS:
 * Interface and crash fixes


I also noticed that the GPU accelerated post-processing stopped crashing on my rig, even with 1080p at six-fold speed   :)

3D-Tech News Around The Web / eyeon's Fusion 6.1 now supports OpenCL

eyeon unveils the next generation of the GPU Supercomputing  framework in Fusion® 6.1. This is not just an acceleration technology; this is unprecedented productivity advancement.

Exploiting the power of low cost GPU graphics cards with hundreds of cores, coupled with an expanded feature set, makes this release much more productive. The need for network rendering becomes greatly reduced, keeping the studio's infrastructure manageable and cost effective.

3D scene importing via FBX has been greatly expanded, streamlining the process between 3D animation and rendering to directly have the same assets working in Fusion. Produce passes and layers on the fly directly on the GPU at breath-taking speed. Cutting reliance on other applications and departments simplifies the production process.

Fusion 6.1 accelerates from the starting line with astounding GPU optimizations, local file caches and particle solution caching. The creative horizon expands with new tools for managing grain, color correction and handling metadata. Scripters will rejoice at the inclusion of native python support, and everyone benefits from the many enhancements to particles.

Fusion 6.1 now supports the OpenCL language, which allows tools to take advantage of the GPU in modern NVidia and ATI graphics cards to achieve blazing speed increases. How fast? We are seeing improvements as much as 1000% on some of the most processor intensive tools in Fusion (e.g. Defocus, Noise generators). Insert OpenCL code directly into Fuse tools to create your own GPU-accelerated tools.

OpenCL’s open computing language is a framework that utilizes the massively parallel operations of GPU's for general computing. Instead of just doing 3D OpenGL rendering on graphics cards, more general processing can be achieved at orders of magnitude faster than possible with just CPU's.

In recent years, the use of GP-GPUs for HPC has sparked quite a bit of interest. ... While there were more entries in the field (Cell and Larabee), the GP-GPU market has tuned into a two horse race with NVidia and AMD/ATI leading the way. From an HPC perspective, the GP-GPU can be considered a SIMD parallel co-processor (Single Instruction Multiple Data) Indeed, graphic processing is by its nature a SIMD process and it makes sense to borrow the hardware for other SIMD applications like those in HPC.

3D-Tech News Around The Web / SmallLuxGPU v1.6 (OpenCL)
« on: July 02, 2010, 01:10:03 PM »
SmallLuxGPU is a LuxRays demo and a LuxRender v0.8 "proof of concept".

Real-time sequences were recorded on a i7 860 + HD5870 + HD5850 at the resolution of 800x450.
Off-line sequences were rendered with a i7 860 + HD5870 + HD5850 at the resolution of 1280x720.


SmallLuxGPU and LuxRays are released under GPL license and the sources are available here.
Precompiled binaries are available on LuxRender forums (check the section dedicated to GPU acceleration).

I like their philosophy: "CPU Vs GPU ? No, thanks, CPU + GPU + Network rendering is better"

AMD’s ATI Radeon HD 5800 series was launched just over nine months ago. Since then, AMD has been true to its word releasing new driver updates every month. Our question is, "Have we seen driver performance improve since launch?" Certainly drivers updates and performance increases have traditionally gone hand in hand, and we have seen some mighty performance boosts with the latest NVIDIA drivers. Now we want to see how far along the Radeon HD 5870 has come since its first install into our PCIe slots.

Today’s testing is simple, we are going to take six games and compare different driver versions in an apples-to-apples comparison. We are using three different drivers. The first is the actual launch driver we used on September 22nd, 2009, when the Radeon HD 5870 launched. We will then compare that to the first official WHQL release for the Radeon HD 5800 series which is Catalyst 9.10 WHQL. Finally, these will be compared to the current Catalyst 10.6 WHQL driver to see if performance has improved over these last nine months. All testing below is done with a single stock Radeon HD 5870 1GB.

The June 2010 release of SlimDX focused on filling in existing APIs and adding missing functionality. In addition to implementing most of DirectWrite and ensuring that Direct3D 11 support was feature complete, the June 2010 release also refactored shared shader and effect functionality into a common D3DCompiler namespace. Several new samples were added to showcase advanced interop features, and a .NET 4.0 build was added, along with VS 2010 support. On top of these additions, the usual array of bug fixes and feature enhancements were made to continue improving the stability of the SlimDX library.

SlimDX has been out of beta for almost two years now. Since first released, the team has tried to keep breaking changes to an absolute minimum. This has led to a number of desired changes being postponed in favor of backwards compatibility. During the past few months the SlimDX team has been doing initial design work and planning for a tentatively named "SlimDX 2.0" version, which will incorporate numerous breaking changes and enhancements to the library's core design. This "2.0" version is currently slated for a late 2010 release, making June 2010 one of the last "1.x" releases.
