3D News

Contest closed - stay tuned to 3DVisionlive.com for details about upcoming contests.     3DVisionLive.com is excited to unveil the latest in a series of photo contests aimed at giving you a platform to show off your images and potentially win some cool prizes. Like our most recent Spring Contest, this one will span three months - October, November, and December - and is themed: Your image must be something that captures or shows the essence of "nature" and what...
With sincere apologies for the delay, NVIDIA is pleased to announce the results of the Spring Photo Contest. We received more than 80 submissions from 3DVisionLive members and, for the first time, invited the membership to select the winner. The only criteria for the contest was the photos had to represent the meaning of Spring in some fashion, and be an original image created by the member that submitted it. All submitted photos were put in a gallery and ample time was...
For the third year in a row, NVIDIA worked with the National Stereoscopic Association to sponsor a 3D digital image competition called the Digital Image Showcase, which is shown at the NSA convention - held this past June in Michigan. This year, the 3D Digital Image Showcase competition consisted of 294 images, submitted by 50 different makers. Entrants spanned the range from casual snapshooters to both commercial and fine art photographers. The competition was judged by...
  VOTING IS NOW CLOSED - Thanks to all that participated. Results coming soon!   The submission period for the Spring Photo Contest is now closed, and we are happy to report we’ve received 80 images from our members for consideration. And, for the first time, we’re opening the judging process to our community as well to help us determine the winners. So, between now and the end of June (11:59 PST, June 30st), please view all of the images in the gallery and place...
Okay, we've gone over all the submissions for our first Winter Photo Contest and debated at length over our favorites. And, we've finally come to a consensus, which will introduce our second, second-time contest winner: ZZ3D.   First Prize: Snow Fight   ZZ3D's a long-time contributor to 3DVisionLive and has shared some amazing work with us. Snow Fight is certainly no exception! We felt this image captured the essence of the contest's Winter theme very well, and...

Early flight simulators maneuvered a closed circuit TV camera above a physical terrain model to mimic flight.

Today’s simulators are complex computer systems that render terrain databases ranging from hundreds to thousands of square miles. Systems such as NASA’s OBVA simulator use multiple 4K projectors to provide a scene with 20/10 visual acuity.

These “virtual reality” training environments let pilots suspend their disbelief so they feel like they’re flying a real aircraft. With the stakes so high in learning to fly commercial planes, the last thing you want is to spoil the illusion.

Yet visual scientists have shown the human eye can detect the slightest imperfection or dropped frame within a scene at ultra-high resolutions. That’s why so many flight simulators rely on professional-grade NVIDIA Quadro GPUs to create a perfectly synchronized image.

Industrial strength: The projector array used to create NASA’s OBVA simulator.

“Our goal is to make pilots forget they are in a flight simulator,” said Tim Woodard, chief technology officer at Diamond Visionics, a New York-based maker of 3D visualization tools. “With the Quadro M6000, we saw a 100 percent performance improvement over the previous generation, while maintaining a 60Hz frame rate at 4K resolution.”

Image Society’s annual IMAGE event for visual simulation attracts experts from fields such as laser display technology, vision science and display screens. (Of course, they’ll be using NVIDIA GPU technology to drive the visuals.)

At this year’s conference, taking place July 7-8 in Dayton, Ohio,  Shalini Venkataraman, a senior application engineer at NVIDIA, and I will lead a session on how to unlock NVIDIA’s Maxwell GPU architecture to create greater levels of realism.

In a separate session, Diamond Visionic’s Woodard will talk about his  how his company uses NVIDIA OpenGL.

We hope to see you there. In the meantime, learn how you can use NVIDIA’s Scalable Visualization Solutions (SVS) technology for flight simulation, or contact us at QuadroSVS@nvidia.com.

Gamers may have been the first to enjoy the benefits of GPU technology. Today it has grown into many areas of enterprise and supercomputing where it packs an impressive punch.

Now a team led by Peter Vincent, a senior lecturer in the Department of Aeronautics at Imperial College London, is giving CFD technology a 10x boost with the launch of the new GPU-accelerated PyFR v1.0.0.

Computational Fluid Dynamics is the computational simulation of fluid flow. It helps engineers understand complex air and fluid flow patterns without building a wind tunnel. They’re incredibly helpful when designing aircraft, wind turbines and even F1 racing cars.

Meet the Next Generation

PyFR is an open-source CFD package that employs new, very accurate methods known as Flux Reconstruction schemes to tackle some of the world’s most challenging fluid flow problems. In particular, problems where the flow is unsteady and turbulent.

PyFR works on a range of hardware platforms, including large-scale clusters powered by the NVIDIA Tesla Accelerated Computing Platform.

Why use Tesla GPU accelerators? Their many-core architecture is the key. While the average modern laptop has two to four cores, the NVIDIA Tesla GPU accelerators

Vincent is using have more than 2,500 ultra-high performance compute cores. The new CFD software runs on clusters of hundreds of these GPU accelerators. So these systems can make billions calculations every minute, processing vast amounts of data.

Accelerating the Future

Early results have generated excitement in the CFD community. A study presented at the AIAA Aviation conference in Dallas this week indicates that GPU-accelerated PyFR can achieve 10x increases in accuracy and efficiency.

Aerospace industry leader BAE Systems has been a close collaborator. “We regard PyFR’s numerical accuracy, algorithmic and parallel performance as a benchmark for other codes,” said Oscar Neilson from BAE Systems UK. World-class aerodynamics has been key to the UK’s success in the aerospace sector. It plays a vital role in the aerodynamic design of aircraft, allowing engineers to understand complex airflow patterns without ever flying a real aircraft.

It’s a big deal as well for someone like H.T. Huynh from NASA’s Glenn Research Center, which aims to advance our exploration of the solar system. “To me, PyFR is a game changer,” said Huynh. “It has caused me to re-evaluate my research as well as my path forward. I hope to make extensive use of this remarkable and elegant program.”

Whether engineers will use PyFR to develop the next F1 winners or airplanes that can take us into space and back, this is yet another industry being turbo-charged by the power of GPU technology.
