3D-Tech News Around The Web / Larrabee: first public demonstration

Intel has given the first ever public demonstration of its long-awaited Larrabee graphics system.

"Larrabee gives you a fully programmable rendering pipeline. So you can use DirectX, or OpenGL - or your own pipeline."

"These reflections here are just ten lines of code," he stated. "To do something like this on a conventional GPU would be really quite painful."

Developed by LucidLogix and dubbed HYDRA, the technology was set to revolutionise multi-GPU graphics by eliminating the need for specific, limited driver support from either ATI or NVIDIA in the form of CrossFireX or SLI, respectively. Rather, sitting in-between the DirectX API and graphics cards, Lucid employed a manufacturer-agnostic chip and associated software that latched on to the PCIe bus to mete out the necessary data to two-, three-, and four-card combinations.

So, a year or so later, LucidLogix is back with a newer HYDRA 200 chip. This time around, however, the company has leveraged the support of a tier-one motherboard vendor, and we'll be seeing the HYDRA-powered board in a few weeks' time.

There are several key features in DirectX 11 that will make graphics on the screen look closer to reality. Tessellation is used to increase the polygon count in an image. The more polygons, the more realistic the image will look. Gone will be the days of blocky looking characters as the polygon count will increase significantly with the next generation of DirectX 11 hardware.

Multithreaded rendering will allow Direct3D processes to run across multiple CPU cores. Most games are using dual core CPUs, but multithreaded rendering will make gaming on triple and quad cores finally worth the cost. A faster processing pipeline and increased scaling are only some of the benefits.

DirectCompute allows access to the shader cores and pipeline. It allows for non-proprietary physics implementations, which some open-source physics projects are looking to take advantage of. Video transcoding will also take a significant leap due to access to the many processors on a modern GPU.

As far as AMD+Pixelux announcement go, there isn't exactly much to be discussed - Pixelux will work closely with AMD in order to push OpenCL CPU+GPU acceleration of its Digital Molecular Matter Engine, and the platform of choice is AMD Opteron with ATI Radeon 5800 series and FirePro graphics cards.

The Adobe Pixel Bendertechnology delivers a common image and video processing infrastructure which provides automatic runtime optimization on heterogeneous hardware. You can use the Pixel Bender kernel language to implement image processing algorithms (filters or effects) in a hardware-independent manner.  The Pixel Bender graph language is an XML-based language for combining individual pixel-processing operations (kernels) into more complex Pixel Bender filters.

Atangeo Balancer is a tool to optimize and simplify 3D models. Its exceptional performance and a novel user interface allow finding perfect balance between visual appearance and the number of polygons, quickly and easily. Balancer utilizes a high quality polygon reduction (aka mesh simplification or decimation) to preserve the visual appearance of your model. The model features, normals, texture coordinates, layer boundaries are all honored by Balancer. It can optimize your models even further to dramatically speed up rendering of your models. Balancer features a fast and efficient triangle reordering that can be tuned for various rendering methods like triangle strips and array/buffer based rendering. Balancer Lite is a free version. It is fully functional but works with small meshes only. The limits for a single mesh are 15000 triangles and 10000 vertices.

3D-Tech News Around The Web / Asus MARS Quad SLI - Extreme Gaming

With Nvidia not going ahead with an enhanced GTX295 ASUS have decided to do so themselves and the result of this venture is their MARS card. In addition to cores which are higher specification than the standard GTX295 Asus have also pushed the cards as far as they can go in terms of memory support with each GPU having access to 2 GB of GDDR3... that’s 4 GB per MARS card, more than enough to make enthusiasts and benchmark junkies drool with excitement.

So today we see how much of an improvement the MARS card is over a standard GTX 295 but we won’t stop there... we will also pair two of these cards in SLI to create a configuration which is essentially the same as GTX 285 Quad SLI. Asus have basically rewritten the Nvidia rulebook – so today we find out if this incredible engineering creates a card that is significantly better than anything else currently available.

Researchers develop specialized hardware to render holographic projections at near real-time speeds. The framerate leaves a bit to be desired, however, so don't throw your 3D glasses away just yet.

With the launch of Snow Leopard this Friday, now is the time to start getting revved up for some of the new technologies coming with this release. One of them, OpenCL, is near and dear to my heart. And this tutorial series will hopefully help getting many of you acquainted with the technology and what it can do. Instead of doing text tutorials, I've decided to present these as video tutorials.

Gigabyte adds two more graphics offerings to saturated mid-range video card market.

The GTS 250 is the successor to the highly-capable 9800 GTX+ and Gigabyte's version of the GTS 250 sports 1GB of GDDR3 memory as well as a custom low-profile GPU cooler made by Zalman. Gigabyte claims this GPU heatsink will help users see overclocking gains between 10 and 30 percent.

The 9600GT also sports quite a few impressive features this price point that include support for DirectX 10, Shader Model 4.0, OpenGL 2.0 and NVIDIA's PureVideoHD technologies. The card's core clock runs at 650MHz, relieving your CPU of pixel crunching duty.
