Stereo Unprojection

This document exposes the technical problems faced in stereo with nvidia driver automatic mode when
the fragment position must be unprotected in mono space in the pixel shader.

How to enable steroscopic 3D in eDrawings

using eDrawings in 3D requires a few relatively easy steps to change the
default setting.  nViDia is working with eDrawings so future versions will
simply require a button click.  but, for now, follow these simple instructions
and get ready to put on your 3D glasses!

Kodu is a new visual programming language made specifically for creating games. It is designed to be accessible for children and enjoyable for anyone. The visual nature of the language allows for rapid design iteration using only an Xbox game controller for input (mouse/keyboard input is also supported).

3D-Tech News Around The Web / AMD OpenCL Emulator-Debugger
« on: March 01, 2011, 05:12:47 PM »
The OpenCL Emulator-Debugger (ocl-emu) is an open source project originating at AMD that allows you to compile and debug OpenCL kernels as C++ procedures. The goal of the project is to provide OpenCL developers with the full support of Microsoft® Visual Studio® C++ development and debugging environments.


    * Compile and debug code within Visual Studio
    * Concentrate on your code rather than the intricacies of the OpenCL runtime, for example:
          o For beginners – get a one-line call “Hello World” kernel
          o For algorithm developers – you can focus on the massive parallel algorithm(s) rather than the OpenCL runtime
    * Enable an easy switch from emulator, CPU or GPU devices for a correctness verification and performance tuning
    * Avoid most OpenCL language compilation errors using the Visual Studio compiler as a syntactical checker

3D-Tech News Around The Web / LuxMark v1.0 OpenCL benchmark
« on: February 25, 2011, 10:56:04 PM »
LuxMark is a OpenCL benchmark tool. The idea for the program was conceived in 2009 by Jromang. It was intended as a promotional tool for LuxRender (to quote original Jromang's words: "LuxRender propaganda with OpenCL"). The idea was quite simple, wrap SLG inside an easy to use graphical user interface and use it as a benchmark for OpenCL. After Anandtech adoption of SLG as OpenCL benchmark, the code was finally written.

3D-Tech News Around The Web / NVIDIA OptiX 2.1 RC 2
« on: February 23, 2011, 09:57:23 PM »
The OptiX team is pleased to announce that the second release candidate for version 2.1 of the NVIDIA OptiX ray tracing engine is now publicly available to all software developers.

Here are some of the highlights of the changes from version 2.1 RC1 (please see the Release Notes in the distribution for complete details)

    * RtuTraverse API changes (your application will need to be recompiled) This API is currently in Beta.
          o Automatic fallback to CPU when no NVIDIA GPU is present
          o Sped up CPU fallback path
          o See documentation for new capabilities, including optional return data for ray hits
          o Added missing traversal sample
    * The OptiX libraries no longer link against nvcuda.dll or This allows apps linking to OptiX to execute on machines that do not have an NVIDIA driver installed. This also enables the the CPU fallback option of rtuTraverse.
    * Sped up SBVH builds up to 2x
    * Fixed bug on G80 GPUs where it complained about cuMemAlloc

Samples failed to run on my ATI notebook   :P

Version 3 of the Cg Toolkit adds capabilities and profiles to fully support all currently shipping graphics boards from NVIDIA.

The February 2011 version of Cg 3.0 added these improvements:

    * Improved DX11 tessellation support
    * Resolved an issue with nearly identical user defined types
    * Resolved an issue with default values from unreferenced uniform parameters
    * Support setting matrices beyond 96 float constants in the vp30 profile
    * Application supplied compilation options now override those set by cgGLSetOptimalOptions
    * Improved support for 'const' variables in the GLSL profiles
    * Added sampler state documentation

Quiz: which screenshot has been made with ATI GPU?  ;D

New Line of Professional Mobile Graphics Solutions Built on NVIDIA Fermi Architecture and Optimus Technology

SANTA CLARA, Calif. — February 22, 2011 —NVIDIA announced today a new line of Quadro® professional graphics solutions for mobile workstations. Designed for engineers, industrial designers, animators, and film & video editors that need to take their work with them, these new Quadro graphics processing units (GPUs) leverage the NVIDIA Fermi architecture, which combines fast visualization performance with high performance computing capabilities. This massively parallel processing horsepower transforms laptop computers into mobile super computers.

Featuring twice the number of CUDATM cores and twice the graphics memory over previous generations, these new Quadro GPUs also incorporate NVIDIA OptimusTM technology, maximizing battery life by automatically powering the GPU only when needed. Optimus also provides users with the ability to drive up to four displays at the same time.

Building on a decade of innovation and leadership in professional mobile graphics, the new Quadro line of mobile graphics solutions includes:

* Quadro 5010M (Ultra-High End): 384 CUDA cores; 4 GB GDDR5 memory; designed for new 17.3-inch mobile workstations

* Quadro 4000M (High End): 336 CUDA cores; 2 GB GDDR5 memory; designed for new 17.3-inch mobile workstations

* Quadro 3000M (High End): 240 CUDA cores; 2 GB GDDR5 memory; designed for new 17.3-inch mobile workstations

* Quadro 2000M (Mid-Range): 192 CUDA cores; 2 GB DDR3 memory; designed for 15.6-inch mobile workstations

* Quadro 1000M (Mid-Range): 96 CUDA cores; 2 GB DDR3 memory; designed for 15.6-inch mobile workstations

“Year after year, NVIDIA innovations demonstrate true technology leadership,” said Dr. Jon Peddie, president of Jon Peddie Research. “Optimus is perfect for anyone who needs high performance, long battery life, and additional displays. With this new Quadro mobile lineup based on the Fermi architecture, NVIDIA is poised to continue its dominance in mobile workstation graphics.”

The new standard for mobile workstation graphics excellence—the NVIDIA Quadro 5010M

The flagship Quadro 5010M features Error Correction Code (ECC) and fast, 64-bit double precision capabilities to ensure the greatest accuracy and fidelity of results. From medical imaging to structural analysis applications, data integrity and precision is assured, without sacrificing performance.The Quadro 5010M features an unprecedented 4 GB of fast GDDR5 memory to enable interactivity on the largest projects. Shattering previous 3D graphics benchmarks, professionals on the go can achieve nearly a billion triangles per second with this ultra high-end Quadro mobile graphics solution.

NVIDIA Quadro technology creates mobile super computers

Similar to the NVIDIA Quadro 5000M, the groundbreaking NVIDIA Fermi-based mobile workstation graphics solution announced last year, and currently available in both the Dell Precision M6500 and HP EliteBook 8740w mobile workstations, additional features of these new NVIDIA Quadro mobile professional graphics solutions include:

* The NVIDIA CUDA parallel computing architecture – Quadro mobile GPUs deliver massive performance gains when running computationally intensive applications such as ray tracing, video processing and computational fluid dynamics.

* NVIDIA 3D VisionTM Pro – support for the highest quality, stereoscopic viewing experience is helping drive the development of 3D capable visualization applications from companies such as Autodesk, Dassault Systemes, Siemens and Agilent.

* NVIDIA Scalable Geometry EngineTM technology – dramatically improves performance across a broad range of CAD, DCC and scientific applications, enabling a user’s work to flow interactively with models and scenes that are an order of magnitude more complex than ever before.

* NVIDIA GPU Tessellation Engine technology – with support for OpenGL 4.1, Shader Model 5.0 and DirectX 11, tessellation automatically generates finely detailed geometry for cinematic quality environments and scenes without sacrificing performance.

* Application certification - support for the broadest spectrum of professional applications, including those utilizing OpenGL 4.1, Shader Model 5.0, and Microsoft DirectX 11, plus DirectCompute and OpenCL standards. Companies such as Adobe, Autodesk, and Dassault Systemes certify NVIDIA Quadro solutions for professionals whose livelihoods depend on maximum uptime with their applications.

Mobile workstation manufacturers have relied on NVIDIA GPUs for the past decade, and will integrate these Quadro solutions in their newest mobile workstations scheduled to be announced throughout 2011. For more information about NVIDIA and Quadro Mobile Graphics Solutions, please visit
