This document provides development hints and tips to ensure that your customers will have a great experience playing your games and running other interactive 3D graphics applications on Intel Processor Graphics. This document details software development practices using the latest generation of Intel processor graphics with a focus on performance analysis using Microsoft DirectX*. Intel tools useful in optimizing graphics applications are introduced in a section detailing performance analysis with the Intel® Graphics Performance Analyzers (Intel® GPA).

Intel® HD Graphics is split into product generations, the latest of which was introduced in January, 2011 with Intel® microarchitecture code name Sandy Bridge.  This family of processors is now on the same silicon as the CPU - a first for Intel® HD Graphics. Each year, more capabilities and better performance are provided by new processor graphics cores. Intel processor graphics currently represent the most common graphics solution chosen by new PC purchasers. Therefore, it makes sense to write your 3D applications to take advantage of this broad market and optimize the experience for the greatest number of people. By following the tips and tricks in this document, you have the opportunity to make your application shine with the graphics volume market leader.

AVX Cloth - Developer Video



Colony (DX11) is a highly parallel optimized crowd simulation technique. Tens of thousands of units are simulated using a novel ray-casting technique. This is achieved by utilizing TBB to distribute our work across multiple threads and multiple frames and utilizing SIMD to ensure further instruction-level parallelism.



Fireflies (DX9) is a tech sample demonstrating a scalable ambient effect. In this sample, the ambient effect is a swarm of fireflies that scatter and reform into a walking character. Using Intel TBB, the firefly flight trajectory calculations performed per frame are distributed across multiple threads. By changing the number of simulated fireflies programmatically the ambient effect can be scaled to better match the performance of the platform it is running on.

3D-Tech News Around The Web / Blender 2.56 Beta
« on: January 01, 2011, 12:46:18 PM »
Quote
The Blender Foundation and online developer community is proud to present Blender 2.56 Beta. This release is the fourth official beta release of the Blender 2.5 series, representing the culmination of many years of redesign and development work.

This version is called a "Beta" because it's now for the most part feature complete. The Python API has had some extensive changes, most notably in naming conventions and in creation and access of properties.

Since Blender 2.55 beta over 440 bugs were fixed!

IMPORTANT: Between 2.53 and 2.56 an extensive renaming operation has changed the scripting API a lot, with repercussions also for loading 2.53 .blends with animation into 2.56. Make sure you try the FCurve/Driver 2.54 fix entry from the Help menu.

IMPORTANT 2: The day after release, a very bad bug in "undo" for using Cloth/Fluid sim has been solved. We'll probably release a 2.56a update soon.

KlayGE is a cross-platform open source game engine with plugin-based architecture. In this new version 3.11.0, the OpenGL plugin is highly enhanced. It replaces the D3D9 plugin to become the primary rendering plugin under WinXP. Also, it now works well on both NVIDIA and AMD graphics cards, from OpenGL 2.0 to the latest 4.1.

Most prerequisites are already in application folder, except from Cg toolkit.

DX11 worked fine, OpenGL appeared very unstable with Cedar/Cat10.12
I strongly recommend to use gdebugger.

Synthesizing Subdivision Meshes using Real Time Tessellation

We propose a new GPU method for synthesizing subdivision meshes with exact adaptive geometry in real time. Our GPU kernel builds upon precomputed tables of basis functions for subdivision surfaces and is therefore supporting all subdivision schemes, either interpolating or approximating, for triangle or quad meshes. We designed our kernel so that it can be integrated seamlessly within a standard tessellation pipeline, exploiting software or hardware (adaptive) tessellation methods. We make use of the tessellator unit as an adaptive mesher for maximum subdivision level, exploiting the linear nature of subdivision surfaces to enable arbitrary level of detail adaptivity and %extend the idea of Subdivision Shading to control the visual smoothness using the same tables as control the visual smoothness using Subdivision Shading by applying the same tables as for geometry. We evaluate our kernel on a variety of dynamic meshes and compare it to subdivision substitutes.

For some reason it didn't run on my Cedar rig  ???
