Visualization Systems


The SunCAVE is a 360-degree, virtual reality space. The model for this will be a room at QI currently outfitted with 70 3D stereo ultra-high definition 4K panels (45 screens in front and another 25 behind) driven by 70 Nvidia 1080 GPUs. The 500 megapixel display tilts at both the top and the bottom for an encompassing experience that gives the space a sphere-like appearance. Wearing lightweight passive glasses, visitors can interactively engage with presentation through the use of an ART optical tracking system.

Tucked into a cozy-feeling room on the first floor of the UC San Diego Qualcomm Institute’s Atkinson Hall are 70 screens, bundles of cables and 35 computer nodes that make up a powerful system that can process massive amounts of data transmitted over the Internet from researchers all over the US or even Antarctica.

It can also take you, virtually, into worlds as varied as a temple in Egypt, an ancient copper smelting site in Jordan or an underwater cave system on the Yucatan Peninsula. Or even into the abdomen of Crohn’s disease patients.

Tapping into the power of cluster computing, the SunCAVE today offers much more than just visuals; it’s become a powerful tool for machine learning and data analysis as well.  Think of it as your TV being equipped with a supercomputer, becoming a visualization system that can also compute what it’s seeing. Only much bigger, brighter and faster— and connected to a host of other computers worldwide at speeds more than 1,000 times faster than your laptop.

“It’s a beautiful object, a giant gem. There’s nothing like it in terms of intensity and resolution,” said Tom DeFanti, a research scientist at the Qualcomm Institute, the UC San Diego Division of the California Institute for Telecommunications and Information Technology (Calit2).

“The fact that we can use 35 PCs and  70 game-class graphics cards (GPUs) and memory together makes it a computer cluster that also happens to immerse you in realistic 3D pictures, algorithmic visualizations, and even MRI-scans of human brains and other organs,” he said.  (See the graphic at the end of the story for more specs.)

First unveiled in 2007, the StarCAVE was designed by a team of scientists and Internet and virtual reality pioneers: DeFanti, who coined the term CAVE while a professor at the University of Illinois at Chicago for its VR room, Greg Dawe, a Qualcomm Institute principal design engineer, Ramesh Rao, the Qualcomm Institute director, Larry Smarr, the director of Calit2, and Calit2 research scientist Jurgen Schulze, who developed the software to run it.

The Qualcomm Institute’s current CAVE, the SunCAVE, was built ground up, panel by panel, by Dawe and UC San Diego Department of Music alumnus Joel Polizzi ’14. Polizzi, a visualization engineering technician at the Qualcomm Institute, is now helping the SunCAVE enter the next generation with fellow alumnus Isaac Nealey ’18, a graduate of the Visual Arts department and a visualization software developer at the institute. They have integrated additional applications and tools such as ParaView and Unreal Engine to create more dynamic scenes and realistic, 3D video game experiences.

By offering its cluster computing capability to a variety of researchers, the SunCAVE is uniting a community of users who can tap into this Kubernetes-orchestrated system to use and share resources. (Kubernetes is Google’s popular open-source software for making large numbers of diverse computer platforms work together. The Qualcomm Institute was an early adopter.)

The SunCAVE was built with funds from National Science Foundation.

Larry Smarr, the Calit2 director, talks here about his Crohn’s disease and the role that VR, including the SunCAVE, played in his diagnosis and treatment.
