NVIDIA demo GPU-based Interactive Ray Tracing

NVIDIA is demonstrating its latest efforts in interactive ray tracing at SIGGRAPH 2008, using four next-generation Quadro GPUs in an NVIDIA Quadro Plex 2100 D4 Visual Computing System to show linear scaling during rendering of a complex, two-million polygon, anti-aliased automotive styling application. The images here are taken from the demo, which managed 30fps 1920 x 1080 High Definition video for an image-based lighting paint shader, ray traced shadows, reflections and refractions.

The Liquid Resize Technology Found Home

If you are a digital photographer or graphic designer, you probably seen the demo of Contact_Aware Image Sizing video posted on the web during the Siggraph 2007. The presentation wowed me, they are using a unique image resizing algorithm known as ‘seam carving’ to calculate then alter the least important pixels of an image to reduce geometric distortion. The Content Aware, aka Liquid Resize or Retarget was originally developed by a husband-wife team of Ramin Sabet and Irmgard Sabet-Wasinger from Vienna, Austria. It was based on the algorithm co-invented by Shai Avidan and Ariel Shamir from Mitsubishi Electric Research Labs. The ground-taking technology is now officially acquitted by onOne Software, an imaging software company that also brought you variety of Photoshop Plug-ins.

Team from USC develops new holographic technology

True 3D holographic displays are something that one would have thought we would have by now. After all, the idea has been around in sci-fi for years, and it seems like it would be fairly simple to do. However, the creation of such a device that is practical for use has proven to be quite difficult to make.
