AMD messed up their download sites again. If the direct downloads: Hotfix 10.10E and CAP2 fail, visit following topics at Rage3D:

AMD Hotfix Catalyst 10.10e With MLAA For Radeon HD 5000 Series Now Available
Rage3D Exclusive - New AMD Catalyst Application Profile 10.10 #2!

This CUDA experiment maps a FULL-HD (1920x1080 @ 30 frames per second, MPEG2 compression) video source into 3D space. Each frame is processed in real-time on the GPU using CUDA. Each pixel in a frame (2.073.600 pixels per frame) is scaled by its luminance value and given the original color. The camera flight is realized with a 3D space navigator in real-time. This application is written in C# using DirectX 11, CUDA.NET and DirectShow.NET libraries. Benchmarks: GPU load is about 85% (GTX 260), GPU memory controller load 25%, CPU (i7-920) is at 20%.

Release Notes - NVIDIA PhysX SDK 2.8.4
November 12th 2010
What's New In NVIDIA PhysX 2.8.4

    * Discontinued the Training Programs.
    * Added source code of NxTetra (tet-maker) utility to source distribution.
    * Removed spin waits from sample code.
    * Added API to permit the user to specify the order in which compartments are simulated.
    * Added compression limits to cloth.
    * Cloth simulation no longer performs prediction for kinematic rigid bodies for improved interaction behavior.
    * New 'driverless' PhysXLoader for PC CPU distribution.
      In 2.8.4, application developers must ship PhysXCore.dll, PhysXCooking.dll, the cudarXX_XX_X.dll and physxdevice.dll with the application 'locally', in the directory where the .exe is located:
          o The application requests PhysXCore or PhysXCooking (v 2.8.4) from the PhysXLoader.
          o PhysXLoader searches for another DLL called 'PhysXUpdateLoader'.
          o If PhysXUpdateLoader is not found, PhysXLoader will load the local PhysXCore or PhysXCooking.
          o If PhysXUpdateLoader is found, it looks for an updated replacement for the PhysXCore or PhysXCooking dlls.
          o If PhysXUpdateLoader cannot find the specified replacement DLL, PhysXLoader will load the local PhysXCore or PhysXCooking dlls.
          o If PhysXUpdateLoader can find the replacement DLLs, these will be loaded in place of the local PhysCore or PhysXCooking dlls.
    * The net result is that the developer has more control over the game installation process, doesn't have to worry about shipping a large System Software with the game, doesn't have to worry that the player will break his System Software somehow, etc.
    * Better rotation matrix input validity checking.
    * Made Desc::isValid() more verbose.
    * CUDA errors are now reported to the debug stream.
    * Added extended scene statistics for GPU memory usage.
    * Lowered the default GPU memory heap size to 32 MB from 128 MB. You may use NxPhysicsSDKDesc::gpuHeapSize to change how much GPU memory is allocated for physics.
    * Disabled GPU acceleration by default. Clear NX_SDF_NO_HARDWARE to enable it.
    * Corrected inertia and volume computation for capsule. For the same capsule dimension and density, the mass and inertia is slightly different compared to the previous release.

Supported Devices

    * The supported devices are the same as for PhysX 2.8.1 (see below), except that the AGEIA PhysX Processor (PPU) device support was removed.


    * Enabled /arch:SSE2 compiler switch for all optimized PC builds.
    * Optimized PS3 SPU Memory Manager
    * Optimized AgPerfmon AgPerfUtils wrapper
    * Optimized cloth simulation on PS3, XBOX 360, PC CPU

Fixed Bugs

    * Debugged PS3 SPU Memory Manager
    * Fluids now collide properly when static shapes are removed or added.
    * Fixed crash bug in character controller sample.
    * Fixed a number of bugs in the HSM.
    * In the event of a CUDA error (typically a failed launch or an inadequately sized CUDA memory heap), the NxFluid will not allow the addition of any more particles.

Known Issues and Limitations

    * Please also see the previous lists from 2.8.3 and earlier.

API changes

    * Cloth
          o NxCloth::getShapePointers() no longer returns shape flags.
          o Added methods to NxCloth and members to NxClothDesc to set compression parameters.
          o NxCloth::setFlag() can no longer be used to change NX_CLF_BENDING_ORTHO, use flag in NxClothDesc instead.
    * Fluids
          o Removed NxFluidFlag::NX_FF_ENABLE_STATIC_FRICTION. Static friction is enabled by default now.
    * Added NxPhysicsSDK::resizeGpuHeap() to allow changing the GPU heap size after SDK creation. See the GPU Memory section of the User's Guide for details.
    * NxPhysicsSDKDesc::flags has NX_SDKF_NO_HARDWARE set by default.
    * Added checkValid() method to descriptors that return an error code instead of the boolean of isValid().
    * The experimental NxScene::simulateCompartments() method has been added. It gives more control over the order in which compartments get simulated.

The debut of the scalable, multicore Mali-T604 GPU raises the performance bar for visual computing in the consumer electronics space, including mobiles, tablets, DTVs and automotive infotainment. The innovative tri-pipe graphics architecture within the Mali-T604 GPU, addresses the ever-increasing computationally intensive demand inherent in next generation interactive user interfaces and gaming.

I liked the "Omega" 32K demo, not because of the Heavy Metal umlauts, but it reminded me of the Sardine Run somehow.

3D-Tech News Around The Web / NVIDIA Alien vs. Triangles 1.0 Demo available
« on: November 09, 2010, 09:43:36 PM »
NVIDIA "Alien vs. Triangles" Demo

You can turn a smooth, workaday alien into something fun and memorable . . .
possible through the miracle of triangles using a technique we call
multi-dimensional tessellation. You can inject the alien with either a
spikey infection or a fungal infection and watch him deform, as if by magic,
into something new.

For a livelier encounter try the laser weapon. It blasts holes through the
soft tissues of our test subject and proves once and for all, that aliens
really are like onions . . . lots of layers. You’ll see ALL the gooey layers
of an ugly alien in amazing clarity. The wonders of multi-dimensional
tessellation never cease. The future is looking bright indeed!

Recommended System:

NVIDIA GeForce GTX 500 series GPU
2.5 GHz Dual core CPU
2 GB System memory
600 MB Hard drive space
Microsoft Windows Vista or Windows 7

3D-Tech News Around The Web / Inferred Bokeh demo
« on: November 09, 2010, 06:26:47 PM »
This is the result of this thread on bokeh. It's a small demo featuring DOF with Bokeh, SSAO, Bloom and inferred lighting.

The bokeh effect was inspired by lost planet, the details of the implementation are in the linked thread.

You can download the executable and shaders from here. A warning if you're going to delve into the GLSL code though - it's very "proof of concept" (not at all optimal!).

If you don't have MSVC 9/2008 installed, you'll also need the Microsoft Visual C++ 2008 Redistributable.

Requires OpenGL2.1 / DirectX9.0c compatible GPU.
Older GPUs may work, but the bokeh effect probably won't show up (requires vertex texture fetch).
A multi-core CPU is recommended but not required.

Many thanks to the great developers at!

Inspite of using VTF the bokeh effect works on my ATI Cedar. I thought ATI requires R2VB  ???

3D-Tech News Around The Web / Adventures in Fluid Simulation
« on: November 08, 2010, 07:12:39 PM »
Recently I resolved to write my first fluid simulator and purchased a copy of Fluid Simulation for Computer Graphics by Robert Bridson. Like a lot of developers my first exposure to the subject was Jos Stam’s stable fluids paper and his more accessible Fluid Dynamics for Games presentation, while the ideas are undeniable great I never came away feeling like I truly understood the concepts or the mathematics behind it.

As the title reads, there are 391 indy games to check out at IGF, many of them with playable demos.

3D-Tech News Around The Web / OGRE 1.7.2 [Cthugha] released!
« on: November 07, 2010, 06:04:24 AM »
OGRE 1.7.2 [Cthugha] released!

Another six months have passed, and it’s time for another maintenance release to the 1.7 stable branch (codenamed ‘Cthugha’). You can find a list of all the bug fixes after the jump. As usual there are no feature changes or API breakage in this release – we save those for the unstable development branch – which of course you can grab from Mercurial if you want to join us on the bleeding edge.

So far the source releases are ready for download for 1.7.2, the SDK releases are coming soon. If you don’t want to wait, give the source release a try :)

Update 6 November: The VS2008 and VS2010 SDKs are ready for download, as are updated Ubuntu packages in our Launchpad PPA. More to follow!
