If you typically follow GPU performance as it related to gaming but have become curious about Bitcoin mining, you’ve probably noticed and been surprised by the fact that AMD GPUs are the uncontested performance leaders in the market. This is in stark contrast to the PC graphics business, where AMD’s HD 7000 series has been playing a defensive game against Nvidia’s GK104 / GeForce 600 family of products. In Bitcoin mining, the situation is almost completely reversed — the Radeon 7970 is capable of 550MHash/second, while the GTX 680 is roughly 1/5 as fast.

It's what we've always envisioned for Leap Motion — to break down the barriers between people and technology. Here's a video to show you how close we are. With Leap Motion technology, Windows OS is natural, easy, and fun to use. You'll navigate your desktop, browse the web, flip through photos, and do everything you do everyday in extraordinary ways —all with the wave of a hand or lift of a finger.

Modern GPU is code and commentary intended to promote new and productive ways of thinking about GPU computing.

This project is a library, an algorithms book, a tutorial, and a best-practices guide. If you are new to CUDA, start here. If you're already familiar with CUDA, are ready for a challenge, and want to learn design patterns for parallel programming, enjoy this series.

Today's CPUs are capable of supporting realtime audio for many popular applications, but some compute-intensive audio applications require hardware acceleration. This article looks at some realtime sound-synthesis applications and shares the authors' experiences implementing them on GPUs (graphics processing units).

In the last post I gave an overview of my journey through realtime raytracing and how I ended up with a performant technique that worked in a production setting (well, a demo) and was efficient and useful. Now I’m going go into some more technical details about the approaches I tried and ended up using.

Starting May 6th and running for six weeks, Intel wants to inspire developers to forge new ground by integrating voice control, gesture control, facial recognition, and augmented reality with apps and games on PCs in the second phase of its Perceptual Computing Challenge. With a grand-prize of $100,000 USD and  thousands of dollars in prizing available in 4 different categories, Intel is looking for the most unique, innovative, and bar-raising uses of Perceptual Computing possible.
 
Developers have six weeks to submit ideas for games, productivity tools, user interfaces, or generally innovative uses of perceptual computing. If their idea is outstanding it will be selected by the panel of judges to progress into round two, where they’ll receive an interactive gesture camera in order to turn their idea into reality.

libigl is a simple c++ geometry processing library that has a wide functionality including construction of sparse discrete differential geometry operators and finite-elements matrices such as the contangent Laplacian and diagonalized mass matrix, simple facet and edge-based topology data structures, mesh-viewing utilities for opengl and glsl, and many core functions for matrix manipulation which make Eigen feel a lot more like MATLAB.

Science.D.Visions Announces Release 2 (R2) of 3DEqualizer4—Industry-Standard Matchmoving Software
 
Significant Upgrade to 3DEqualizer4 Features Calculation of Multiple Synchronized Witness Cameras (Mocap), Improved Lineup Controls, Streamlined User Interface, New Generation Scripts and Python Commands
 
Dortmund, GERMANY, August 1st 2012—Science.D.Visions today announced Release 2 (R2) of its matchmoving software, 3DEqualizer4. Winning an Academy Award® in 2002 for Technical Achievement, 3DEqualizer site licenses are installed in four of the world’s top ten Visual Effects (VFX) production houses, including Double Negative, Cinesite, Weta Digital, and the Moving Picture Company (MPC). 3DEqualizer helps visual effects and post-production artists measure, merge and ‘matchmove’ live action film sequences and plates with virtual 3D environments and effects to create a seamless look and realistic completed scenes.  3DEqualizer 4 R2 is currently in BETA, and is expected to ship in 2013.
 
3DEqualizer4 R2 Features and Benefits
3DEqualizer4 R2 is currently undergoing an extensive BETA testing cycle, and includes the following new features:
 
• Updated calculation core—allows an artist to compute a variable amount of synchronized  witness cameras for creating precise motion capture data.  The calculation core is fully integrated for stereoscopic calculation and  for creating multiple object point groups
 
• Real-time un-distort footage—lens distortion is visualized in real time, directly in the entire 3DE4 user interface, tremendously improving  the artist’s productivity
 
• Updated Lineup Controls—lining up imported geometry to footage has become dramatically faster through new features such as specialized "lineup only point" dragging, hidden line/ back-face culling rendering, and extracting survey data from vertices/lines/faces.
 
• Streamlined User Interface—new custom focus lens parameters, image controls presets, hide and lock points, automatic key-framing based on tracking deviation,  and an  ‘equisolid angle’  fisheye lens distortion model.
 
• Python commands—Python is the backbone that makes 3DE4 the successful application it is today. This new release features over 100 new Python commands for accessing more project data assets for building much more interactive custom user interfaces. In addition, there are more than 30 new or updated scripts including: rolling shutter compensation export, interactive push points tool, project merging, convert to stereo, and full export to Adobes After Effects—and more.

"The incredibly powerful and accurate way 3DE4 Release 2 handles animated lens distortion, stereo, anamorphic and zoom lenses combined with its ever improving robust calculation core make it Cinesite's matchmove application of choice,” said Michele Sciolette, Head of VFX Technology, Cinesite, UK. “Artists are able to concentrate on the task at hand without any distractions by virtue of the simple UI in 3DE4, while its Python interface allowed us to customize tools and integrate 3DE into our pipeline, resulting in improved efficiency levels. Support-wise Science.D.Visions have always been there for us, and it is reassuring being able to actually get feedback from the developers themselves when you have a question or request."
 
Science.D.Visions has been a pioneer of match moving software for over 15 years, with a customer list including: The Moving Picture Company(UK), Weta Digital(Wellington, NZ), Cinesite (London), Scanline VFX (Munich and LA), Sony Pictures Imageworks(LA), Double Negative (London), The Mill (London), Animal Logic (Sydney), Framestore/CFC (London), New Breed Studios, Rodeo FX, and Hybride (Montréal)—and many other studios that rely on 3DEqualizer to make cinematic magic.
 
Product, Pricing, and Upgrade Information
3DEqualizer4 R2 is available now in solid Beta on multiple operating platforms including Windows, Mac OS X, and Linux. 3DEqualizer4 R2, and is expected to ship in 2013.   For purchase, upgrade, or educational licensing information, contact a direct sales manager for an individual consultation and pricing information at: www.3dequalizer.com/index.html?site=contact
