3D-Tech News Around The Web / ATI Cypress Gaming Performance Analysis
« on: February 22, 2010, 05:12:30 PM »

    *  Cypress is pretty fast versus it's predecessor (+50-60% is not too shabby, in our humble opinion), although it only manages to achieve the 2x performance mark only when DX11 is leveraged in such a way as to improve performance (hey, we warned you back in the architecture piece that there are some points which may limit the upscaling, did we not?)
    * It's primarily bound by its engine clock, so we'd expect any future high-end SKU to try to bump that as much as possible
    * Heavy tessellation isn't cheap, and explaining it solely by "you're setup limited, silly" is a heavy over-simplification
    * We're not really fond of how the Crossfire profiling mechanism ended up being implemented - dear ATI, there's already a solution out there that's well liked by the community, and there have been no reports of users performing ritual seppuku when having to mess with a few extra settings, so please, go and implement something similar rather than reinventing the wheel (yes, we're aware that it was your competitor that came up with it, and yes, we're painfully aware of just how unpleasant it is to program UIs but still, you'd get far far more benefits from doing that)

What's new with Release 1.2

    * Smoke now has a simpler build and builds with Visual Studio 2008 SP1
    * Fixed occasional crash when subdividing objects, after physics collision
    * Fixed a number of memory leaks and uses of uninitialized memory
    * Ambient lighting now lights the shaded side of objects
    * Smoke runs faster, mostly due to speedups in fire object code

I’ve heard a lot about CUDA, such as how it is 10,000% faster at cracking wireless passwords over a conventional program/hardware, but never really got around to testing it out before now. This post details the steps required to compile and setup CUDA 2.3 SDK and toolkit on ubuntu 9.10.

Get the driver here

Note: The TCC driver does not provide CUDA–DirectX/OpenGL interoperability. It is a “non-display” driver, and NVIDIA GPUs using this driver will not support DirectX or OpenGL hardware acceleration.

  Par4All is a platform that merges various open source developments to aim at achieving the migration of software to multicore and other parallel processors.

Pa4All is an open-source environment to do source-to-source transformations on C and Fortran programs for parallelizing, optimizing, instrumenting, reverse-engineering, etc. on various targets.

The interest of the source-to-source approach is to capitalize on the real value of an application (its source!) and generating other sources that can be used by the better back-ends available: optimized compilers for a given processor, vendor compilers for embedded processors, CUDA or OpenCL for GPU, OpenMP, MPI... One source, run everywhere!

3D-Tech News Around The Web / Firefox 3.7 alpha available, supports WebGL
« on: February 10, 2010, 08:41:33 PM »
1) Get it here

2) Enable WebGL

3) search in our forum for "WebGL" to get some samples  ;)

SpiderGL is a JavaScript 3D Graphics library which relies on WebGL for realtime rendering.

SpiderGL provides typical structures and algorithms for realtime rendering to developers of 3D graphics web application, without forcing them to comply with some specific paradigm (i.e. it is not a scene graph) nor preventing low level access to the underlying WebGL graphics layer.

A WebGL-enabled browser is needed to run the examples and demos!

Key Features

    * 3D World editor: CopperLicht comes with a full 3D world editor named CopperCube.
    * Many supported 3D file formats: .3ds, .obj, .x, .lwo, .b3d, .csm, .dae, .dmf, .oct, .irrmesh, .ms3d, .my3D, .mesh, .lmts, .bsp, .md2, .stl. and more, see below.
    * Incredibly fast: CopperLicht is highly optimized and able to render and animate even huge 3d scenes.
    * Simple to use: easily understandable SceneGraph API with lots of tutorials and examples in the documentation
    * Binary compilation: Unlike other WebGL 3D Engines, CopperLicht compiles your 3D meshes into a small, binary file which downloads quickly, reducing bandwith usage for your users. Simply import your 3D files into the CopperCube editor and publish it as CopperLicht scene.
    * Totally free: CopperLicht is free to use. Just download and go!
