We're proud to announce the trailer video for NEXUS, NVIDIA's upcoming Visual Studio-integrated toolset for graphics and GPU Computing. NEXUS includes powerful debugging and platform-wide performance tools.
More information about NEXUS will be available at the GPU Technology Conference, Sept 30th - Oct 2nd, 2009.
Beginning this week we'll be releasing the full text of GPU Gems 3 on the NVIDIA website -- Seven chapters to start, and then three chapters per week between now and GDC 2009.

An updated version of NVIDIA Direct3D SDK 10 has been released. It includes a new sample: the Stencil Routed K-Buffer. Check out the Direct3D samples page to get the whitepaper and code for the new sample, or download the updated SDK here.
The sample shows how to simulate and animate different kinds of lighting effects using DirectX10 features. The structure of a lightning beam is created by using fractal subdivision of line segments, efficiently implemented using geometry shaders and stream out. A geometry shader is then used to create camera facing billboards with a procedurally created color gradient. The atmospheric glow effect is implemented by downsampling and blurring the rendered bolts of lighting using a Gaussian filter kernel with separate extinction coefficients per color channel in order to fake atmospheric scattering.

We are pleased to demonstrate the latest version of our NVIDIA Developer Toolkit at GDC 2007, complete with six all-new software products for developers:
FX Composer 2. Featuring DirectX and OpenGL support via HLSL, Cg, and COLLADA FX, as well as powerful pipeline integration features for real production environments.
GPU-Accelerated Texture Tools. Now more than 10x faster with GPU acceleration via CUDA, and support for DirectX 10 texture formats.
PerfHUD 5. Featuring powerful edit-and-continue for shaders and render states, customizable graphs, DirectX 10 and Vista support, and much more.
ShaderPerf 2. Support for vertex and pixel shader analysis as well as Release 100 drivers.
We are showing off all these tools at GDC in booth # 5134 and at our various sessions. The Shader Library, SDK 10, GPU-Accelerated Texture Tools, and ShaderPerf 2 are now available for download. Betas of FX Composer 2 and PerfKit 5 will be available soon after GDC.
