3D-Tech News Around The Web / Animation of Air Bubbles with SPH
« on: January 28, 2011, 06:16:54 PM »
We present a physically-based multiphase model for simulating water and air bubbles with Smoothed Particle
        Hydrodynamics (SPH). Since the high density ratio of air and water is problematic for existing SPH solvers, we
        compute the density and pressure forces of both phases separately. The two-way coupling is computed according
        to the velocity field. The proposed model is capable of simulating the complex bubble flow, e. g. path instability,
        deformation and merging of bubbles and volume-dependent buoyancy. Furthermore, we present a velocity-based
        heuristic for generating bubbles in regions where air is likely trapped. Thereby, bubbles are generated on the
       fly, without explicitly simulating the air phase surrounding the liquid. Instead of deleting the bubbles when they
        reach the surface, we employ a simple foam model. By incorporating our model into the predictive-corrective SPH
        method, large time steps can be used. Thus, we can simulate scenarios of high resolution where the size of the
        bubbles is small in comparison to the liquid volume.

The NVIDIA Direct3D 10 SDK demonstrates some of the cool, next-generation techniques that are possible with Microsoft’s DirectX 10.   
The SDK includes both Direct3D code samples and whitepapers explaining the effects in detail.

New in This 10.6 Release

1.      An improved version of Instanced Tessellation. This sample implements 3 major schemes for Approximating Catmull-Clark Subdivision Surfaces using instanced tessellation in both DX9 and DX10. In the sample, these three schemes are also compared in terms of their visual quality and performance.

2.      Bug fix for StencilRoutedKBuffer: the previous version would create a DX 10.1 device, resulting in corruption errors.  A modification to DXUTCore prevents the DX 10.1 device from being created for the StencilRoutedKBuffer project.

3.      Upgrade to the June 2010 DirectX SDK: some minor fixes were required because fxc catches more HLSL errors.

4.      Upgrade to Microsoft Visual Studio 2008 because the 2005 version is no longer supported by Microsoft’s DirectX SDK.

Quote from:
3D Shape generator using OpenGL3 and OpenCL

The Belgian scientist Johan Gielis discovered a mathematical formula to describe many shapes existing in nature. This formula is called the “Super Formula”. To demonstrate GPGPU and to show that it can be used for many purposes including simply having some fun, we developed the “SuperShaper”. A tool that uses OpenCL to create very high-detail 3D models using the Super Formula.

If you change sth. and rendering stops, hit a button under "shape deformation style".

AMD Embedded GPU and Chipset XP Driver
AMD Embedded GPU and Chipset Vista/Win7 Driver

January 21, 2011 – Epic Games, Inc. has released the January 2011 UDK Beta, the latest version of the Unreal Development Kit (UDK), the free edition of Unreal Engine 3 that provides access to the award-winning toolset used in blockbuster video games, 3D visualizations, digital films and more.


    * PhysX is now supported on iOS.

Rigid body physics, fracturable meshes and ragdolls are among supported features.
Note: Cloth, fluids and soft bodies remain disabled on iOS for performance reasons.

Running the GLES2 mobile previewer on my laptop is not so convenient  :P

The AMD DB-FT1 development board is an evaluation board for the
AMD Embedded G-Series platform, a low power processor and
advanced GPU integrated into a single embedded Accelerated
Processing Unit (APU). The platform is capable of delivering high
display resolution, up to 2560x1600 pixels, and high performance
multi-media, while maintaining a low-power design in a small form
factor. Its power efficient and space saving advantages are directly
attributable to AMD’s innovative power optimized processor core
design. Therefore, the AMD Embedded G-Series is an ideal platform
for a multitude of embedded applications such as Digital Signage,
Integrated x86 Set-Top-Box (xSTB), Thin Clients, and Casino
Gaming applications that demand high quality multi-media and an
exceptional visual experience.

The AMD-based
x86 Set-Top Box (xSTB)
solution provides the technologies to meet
the needs of today’s high performance set-top box solutions. AMD is
setting the standard in today’s high performance, low power set-top
box designs while leveraging an industry standard small form factor
to help reduce time and costs in bringing the product to market.
Combining AMD’s wide range of powerful 64-bit x86 processors with
high performance integrated graphics solutions provides the basis to
create an xSTB solution to meet the market’s needs. AMD’s xSTB
x86 architecture allows developers to take advantage of the
extensive applications and development that already exist for the PC
market and leverage them for their system development. The AMD
xSTB enables x86 applications on the set-top box including running
some of the latest games and gives the designer a number of
different operating system choices from both Microsoft
® and the Linux® community.

Phew! Actually AMD developers themselves screwed the drivers.

I replaced OpenGL runtimes with those from "Cat11.1 Vancouver 8.810"
These contain the new extensions, however i saw no changes to tessellation with my Cedar laptop.

3D-Tech News Around The Web / AMD Catalyst 11.1a Tessellation Hotfix
« on: January 19, 2011, 12:16:56 AM »
The latest Catalyst Hot-Fix; (11.1a) offers increased performance brings a slew of new features and should be the driver used for any performance testing. Below are a few of the highlights from this driver:


Performance improvements for the AMD Radeon HD 6800 & HD 6900 series include but not limited to:


AMD Radeon HD 6900 and AMD Radeon HD 6800 Series:

    * 3DMark Vantage improves ~7%
    * 3DMark06 improves ~3%
    * Call of Duty Black Ops improves ~20% at 4xMSAA and up to 35% at 8xMSAA
    * Riddick Assault on Dark Athena SSAO performance improves ~20%
    * Unigine Heaven OpenGL performance improves ~10% at moderate, 30% at normal and 100% at extreme tessellation levels


AMD Radeon HD 6800 Series:

    * Aliens vs. Predators improves ~9% at 2xMSAA and up to 20% at 4xMSAA
    * Batman Arkham Asylum improves ~4%
    * Crysis Warhead improves ~2-4%
    * Metro 2033 improves ~28% at 4xMSAA


AMD Radeon HD 6900 Series:

    * Battleforge DirectX 11 performance improves as much as 6%


New Tessellation Controls:

    * The Catalyst Control Center includes an  early prototype of some new tessellation controls.   Our goal is to give users full control over the tessellation levels used in applications.   The default selection “AMD Optimized” setting allows AMD, on a per application basis, to set the best level of tessellation.   The intention is to help users get the maximum visual benefit of Tessellation, while minimizing the impact on performance.  Currently no applications have been profiled, so the “AMD Optimized” setting will be non-operational until further notice.
    * The “Use Application Settings” option gives applications full control over the Tessellation level. Users can also manually set the maximum tessellation level used by applications with the slider control
    * The long term goal for the “AMD Optimized” setting is to use the Catalyst Application Profile mechanism to control the AMD recommended level of tessellation on a per application basis.  AMD’s intention is to set the tessellation level such that we will not be reducing image quality in any way that would negatively impact the gaming experience.

"Wrestler" is now really the codename for Vancouver GPUs
OpenGL 4.1.10428 exposes a new  extension: GL_AMD_shader_trace
GL_MAX_VARYING_FLOATS doubled from 64 to 128
CAL updated to rev. 1016, but no new OpenCL extensions

Apparently i suck at Mobility modding: result OpenGL tessellation factor = ZERO  ;D

3D-Tech News Around The Web / Afterburner 2.1.0 Beta 6
« on: January 18, 2011, 06:55:03 PM »
I am glad to tell everybody that Afterburner 2.1.0 Beta 6 is ready for you to download and play!

The most exciting thing in this beta is the support of HD 6970 and HD 6950.

Now you can tweak voltage of HD 6970 and HD 6950 by afterburner, no matter it uses Voltera VT1556 or Chil 8228 or Chil 8214 PWM chip! Thanks to superb Unwinder!!!!!

We also have some updates on upcoming new cards in thie beta.... so I will let you guys to play on your own

The download link of MSI Afterburner 2.1.0 Beta 6

Note for those who use modded 6950 cards. Afterburner provides voltage control only on reference design 6950 cards with 100% original 6950 BIOS and 6970 cars with 100% original 6970 BIOS. Afterburner's voltage control WILL NOT function if 6970 BIOS is flashed on 6950, it is supposed to be that way and it won't change in future versions and any "bugreports" on it or demands to "fix" it will be ignored.


3D-Tech News Around The Web / CUDA Toolkit 3.2 ERRATA (January 2011)
« on: January 18, 2011, 06:30:15 PM »
NVIDIA CUDA Toolkit v3.2 Errata for Windows, Linux, and MacOS X

Revision History

Last updated 1/14/2011 Version 3.2


Documentation Related
  *  The document- ptx_isa_2.2.pdf in your installation directory has been updated. Get the latest from the 3.2 downloads page:

  *  The command line Compute Profiler document "Compute_Profiler.txt" in your installation directory has incorrect counter names for "instructions_*" . The correct counter names for compute capability 2.0 or higher are as follows:
              inst_issued        inst_executed
              inst_issued1_0     inst_issued2_0
              inst_issued1_1     inst_issued2_1
   i.e. counter names should be "inst_*" and not "instructions_*".

Known Issues

  *  In CUBLAS 3.2, the GEMM, SYRK, and HERK routines for Fermi GPUs can enter an infinite recursion leading to an application crash for certain input sizes meeting the criteria below.  To work around this problem, the input to CUBLAS must be recursively subdivided until the individual calls to these CUBLAS routines do not match these criteria.
Given threshold size T, where T is equal to 2^27 - 512 (i.e., 134217216), the crash might be seen in any of the following circumstances:
      1) A is not transposed, lda * k >= T, and T is divisible by lda.
      2) B is not transposed, ldb * n >= T, T is divisible by n, and n is divisible by 32
      3) A is transposed, lda * m >= T, T is divisible by m, and m is divisible by 32
      4) B is transposed, ldb * k >= T, and T is divisible by ldb.
This issue will be fixed in the next release of the CUDA Toolkit.
  *  For the CGEMM kernel used in some instances on Fermi GPUs when "m" is not a multiple of 16, a few bytes past the end of the "A" matrix are unnecessarily fetched.  Under certain conditions, this can lead to a kernel launch failure (though in no circumstances does it lead to incorrect results).  A workaround for this issue is to round the size of the memory allocated for matrix "A" up to the next highest multiple of 64 bytes.  This issue will be fixed in the next release of the CUDA Toolkit.

Mac Related

  *  To save power, some Apple products automatically power-down the CUDA-capable GPU in the system. If the operating system has powered down the CUDA-capable GPU, CUDA fails to run and the system returns an error that no device was found.
In order to ensure that your CUDA-capable GPU is not powered down by the operating system do the following:
1. Go to "System Preferences"
2. Open the "Energy Saver" section
3. Un-check the "Automatic graphics switching" check box in the upper left
  *  On MacOS only, the NVIDIA C Compiler (nvcc) handles size_t incorrectly during 64-bit compilation. The version of nvcc included with CUDA Toolkit 3.2 fails to handle variables of type size_t as an 8-byte entity in PTX when compiling 64-bit device code. To address this issue, NVIDIA has released a patch that updates components of nvcc.
The patch is available as "CUDA Toolkit: GFEC Patch for MacOS" from the following location:
Please refer to additional information and installation instructions in the README file distributed with the patch.
