3D-Tech News Around The Web / An introduction to OpenGL 4.1
« on: August 26, 2010, 04:55:31 PM »
Less than half year after the revolutionary appearance of OpenGL 4 we now have OpenGL 4.1.The new update concentrates on Shader Model 5.0 class GPUs and extensions and the desktop version of the specification is now downward compatible with its embedded brother OpenGL ES. In this article I would like to present the features introduced with the latest revision of the OpenGL 4.1 specification.

3D-Tech News Around The Web / Afterburner 2.0.0 Beta 7
« on: August 26, 2010, 04:34:44 PM »
Afterburner 2.0.0 Beta 7 is out, in this beta Unwinder added a data filtering option to reject misreading spike caused by resource conflict when using another utility at the same time with Afterburner.

Javor updated his demos. If you need the aforementioned compute caps 1.1 demos gimme a note, i'm sure they are still somewhere on my HDD.

Animation Demo (last update 9 July 2010)
Can load and display .obj key frame animations with direct illumination (Phong) from a single area light (4 samples per point).

Path Tracing Demo (last update 9 July 2010)
Can load and display static .obj scene with a path tracer. It handles Phong BRDF for diffuse and glossy surfaces, and translucent surfaces that do not intersect each other (has Beer's law).

Reductions, which take a vector of data and reduce it to a single element, are widely used in data-parallel programming. In this article, we examine strategies for efficiently mapping reductions onto the ATI Radeon™ HD 5870 GPU and AMD Phenom™ II X4 965 CPU. Taking advantage of properties of the reduction being performed, as well as matching the style of reduction to the hardware platform, can result in performance improvements of up to 15x, compared to naive code.

3D-Tech News Around The Web / NVIDIA Ambient Occlusion Volumes demo
« on: August 25, 2010, 04:56:39 PM »
This paper introduces a new approximation algorithm for the near-field ambient occlusion problem. It combines known pieces in a new way to achieve substantially improved quality over fast methods and substantially improved performance compared to accurate methods. Intuitively, it computes the analog of a shadow volume for ambient light around each polygon, and then applies a tunable occlusion function within the region it encloses. The algorithm operates on dynamic triangle meshes and produces output that is comparable to ray traced occlusion for many scenes. The algorithm's performance on modern GPUs is largely independent of geometric complexity and is dominated by fill rate, as is the case with most deferred shading algorithms.

AOV seems to have no effect with ATI GPU  ::)

Understanding how Direct3D interacts with resources and the command buffer can simplify your engine, enable cross-platform abstractions, and improve performance.
This presentation dispels myths about Direct3D on Xbox 360 and describes a lower-level, engine-friendly approach to managing resources and submitting the scene.

here are the official Xbox Packing Instructions    :P

PixelLight is an open-source, cross-platform 3D application framework written in C++. It currently supports Windows and Linux, and a mobile port for Maemo 5 is on the way. PixelLight has a highly plugin driven architecture with plugins for many third-party middleware such as sound and physics engines, input devices etc. It has a modern deferred shader renderer and currently supports both OpenGL and OpenGL ES 2.0.

Now to the interesting part, some technical details of what can be seen on the screenshots:
- OpenGL renderer (OpenGL 1.1 + extensions)
- Horizon Based Ambient Occlusion (HBAO)
- HDR rendering with Reinhard tone mapping, automatic light adaptation and bloom
- Gamma correction
- Shadow mapping
- Volumetric light scattering (nearly no visual impact within the shown screenshots) and depth fog
- Material features like diffuse and opacity mapping, normal mapping, parallax mapping, two sided lighting, specular and gloss mapping, emissive mapping, glow mapping, fresnel reflection, environment mapping... just the usual must-have stuff for modern 3D engines nowadays

On you'll find some videos, downloadable demos, an SDK for Windows and Linux and of course the URL of our public git repository.

KB 2117917

A beta release of the Platform Update Supplement for Windows Vista is available. This update provides fixes and improvements to graphics, media foundation and print functionality in Windows Vista Service Pack 2 (SP2).

Just like the Windows 7 update it must be a preparation for IE9.

KB 2028560

An update is available for Windows 7 and for Windows Server 2008 R2 which provides new functionality and performance improvements for the graphics platform

Judging from the updated files IE9 must be around the corner...


3D-Tech News Around The Web / Direct3D 11 Multithreading
« on: August 24, 2010, 04:25:42 PM »
There's a lot of interest in the Multithreading features in Direct3D 11, especially since it can be used with existing Direct3D 10.x and 10level9 class hardware as well as new Direct3D 11 hardware. In addition to the Windows DirectX Graphics documentation, here are a number of resources for learning more about Direct3D 11 multithreading:

3D-Tech News Around The Web / OpenGL Samples Pack released
« on: August 24, 2010, 04:21:06 PM »
The OpenGL Samples Pack is available. As the version indicated it, this release includes some OpenGL 4.1 samples for a total of 68 OpenGL samples.

The OpenGL 4.1 has been written upon nVidia beta drivers 259.31 and thus they should be considered as beta samples.

3D-Tech News Around The Web / Metro 2033 PhysX/DX11 demo available
« on: August 21, 2010, 05:15:40 PM »
5 months after (!) release of the retail version a playable demo appeared.
Yet it is technically interesting as it supports GPU PhysX, DX11 Depth of Field and DX11 tessellation.

Mozilla hopes to release its fourth beta of Firefox 4 on Monday, adding hardware-accelerated graphics for some Windows users but leaving it turned off by default.
One way Firefox is tackling the technology is by using Windows' Direct2D interface, which can speed up the display of text and graphics on newer versions of Windows.
