Henry Fuchs

Henry Fuchs is an American computer scientist and the Federico Gil Distinguished Professor of Computer Science and Adjunct Professor of Biomedical Engineering at the University of North Carolina at Chapel Hill (UNC), where he heads the Graphics and Virtual Reality Research Group. Active in computer graphics since the 1970s, he co-developed binary space partitioning (BSP) trees for visible-surface rendering, led the Pixel-Planes and PixelFlow graphics hardware projects, and worked on optical and video see-through head-mounted displays, wide-area tracking, the "Office of the Future" and tele-immersion.

A 1992 paper he wrote with Michael Bajura and Ryutarou Ohbuchi described merging live ultrasound imagery with a head-mounted display user's view of the patient, an application of augmented reality to medical imaging, and his group later used a stereo video see-through display to guide needle biopsies on breast phantoms. He received the IEEE VGTC Virtual Reality Career Award in 2013 and the ISMAR Career Impact Award in 2018, and he is a member of the National Academy of Engineering.

Early life and education

According to the biography published with his 2013 IEEE VGTC award, Fuchs was born in 1948 in Tokaj, Hungary. His family left Hungary after the 1956 Hungarian revolution and emigrated to the United States in 1957. He received a BA in Information and Computer Science from the University of California, Santa Cruz in 1970; the same biography says he was drawn to computer science by the teachers and computer pioneers David Huffman and Harry Huskey.

Ivan Sutherland's 1968 head-mounted display paper drew Fuchs to graduate study at the University of Utah. In a 2015 interview on the Voices of VR podcast, Fuchs said he arrived at Utah in 1970 and recalled a later class of Sutherland's graphics students drawing lines on Sutherland's Volkswagen Beetle and measuring it by hand to build a polygon model, which led him to look for ways to capture 3D shapes automatically. He received his PhD from Utah in 1975. His dissertation, on building surface models of 3D objects by laser scanning, was supervised by Robert Plummer, with Ivan Sutherland, Elliott Organick and Steven Coons. The VGTC biography says that Sutherland's idea of immersion in virtual worlds through see-through displays in tracked eyeglasses "continues to inspire much of Fuchs' work."

Career

Fuchs was an assistant professor at the University of Texas at Dallas from 1975 to 1978 and has been on the UNC Chapel Hill faculty since 1978. At UNC he began a long collaboration with Fred Brooks on what are now called virtual environments, and another with Steve Pizer on 3D medical imaging and displays. His research group, now named the UNC Graphics & Virtual Reality Group, has operated under various names since 1978 and works on 3D scene acquisition and reconstruction, 3D tracking, fast rendering hardware and algorithms, autostereoscopic 3D displays, head-mounted and other near-eye displays, telepresence and medical applications.

Rendering algorithms and graphics hardware

With Zvi Kedem and Bruce Naylor, Fuchs published "On Visible Surface Generation by A Priori Tree Structures" at SIGGRAPH 1980, the paper behind the BSP tree method for ordering polygons in a 3D scene for visible-surface rendering. Earlier, with Kedem and Samuel Uselton, he had published a method for reconstructing surfaces from planar contours in Communications of the ACM in 1977.

The VGTC biography says Carver Mead's idea of a "tall-thin" designer and Lynn Conway's one-semester integrated circuit design course led Fuchs into custom chip design. With John Poulton and other faculty and students he built a series of graphics engines called Pixel-Planes, each of which the biography describes as "among the fastest graphics engines of its day." His UNC research pages say the group has explored 3D graphics architectures since 1980, partly to give UNC researchers in medical visualization, molecular modeling and architectural design exploration more graphics power than commercial systems offered. The 1989 SIGGRAPH paper on Pixel-Planes 5 describes it as a heterogeneous multiprocessor graphics system using processor-enhanced memories. Pixel-Planes 4, Pixel-Planes 5 and their successor PixelFlow ran at UNC for many years and supported real-time medical, scientific and architectural applications in virtual and augmented environments. ACM SIGGRAPH gave Fuchs its 1992 Computer Graphics Achievement Award "for his contributions to high performance, parallel display architecture."

Head-mounted displays and medical augmented reality

The UNC applications in virtual and augmented environments drove work on both optical see-through and video see-through head-mounted displays, including one of the first video see-through displays with matched user and camera viewpoints, designed by D'nardo Colucci. The 1992 SIGGRAPH paper by Bajura, Fuchs and Ohbuchi merged ultrasound imagery with the user's view of the patient. UNC's project pages say the group worked on augmented reality visualization of ultrasound imagery from 1992, first for passive obstetrics examinations, then from April 1995 for ultrasound-guided needle biopsies and cyst aspirations, and later for laparoscopy visualization.

The 1996 SIGGRAPH paper by Andrei State, Fuchs and colleagues describes a real-time stereoscopic video see-through system for ultrasound-guided breast needle biopsy. It combined rendered live ultrasound data with stereo images from head-mounted video cameras, used a hybrid tracking system to improve registration, and was used by a physician who guided a needle into an artificial tumor inside a breast training phantom. In a 2000 paper in Presence: Teleoperators and Virtual Environments, Jannick Rolland and Fuchs compared optical and video see-through head-mounted displays for medical visualization from technical and human-factors points of view, and pointed to eye tracking, multifocal planes and hybrid optical/video designs as future directions. According to the VGTC biography, several of these innovations were commercialized by 3rdTech and InnerOptic and licensed by HP, Ivex and others.

Wide-area tracking

The same applications motivated UNC's work on wide-area tracking, including the inside-out optical tracking dissertation research of Gary Bishop and, a decade later, of Bishop's student Greg Welch. In April 1997 the UNC Tracker Research Group brought its HiBall ceiling tracker online. It used ceiling panels housing LEDs, a small camera cluster called the HiBall, and the single-constraint-at-a-time (SCAAT) algorithm to turn individual LED sightings into position and orientation data. The VGTC award citation lists the HiBall among the large-area tracking systems Fuchs contributed to, and the biography notes that the tracker was commercialized.

Office of the Future and tele-immersion

In Scientific American in 2001, Jaron Lanier wrote that Fuchs had proposed a "sea of cameras" approach to capturing a room and its occupants in 3D as early as 1993, comparing the views of many cameras to reconstruct the scene. Ramesh Raskar, Greg Welch, Matt Cutts, Adam Lake, Lev Stesin and Fuchs presented "The Office of the Future" at SIGGRAPH 1998. UNC describes the project's goals as including a better everyday display environment and 3D tele-immersion between distant offices, using real-time computer vision to extract per-pixel depth and reflectance of walls, furniture, objects and people in an office, so that everyday irregular surfaces could serve as a spatially immersive projected display, and so that dynamic image-based models could be captured and sent over a network for display at a remote site.

The tele-immersion work was carried out in the National Tele-Immersion Initiative, for which Lanier was lead scientist at Advanced Network and Services, with teams from UNC (whose members included Fuchs), the University of Pennsylvania and Brown University. Penn built the real-time camera array, and the Chapel Hill team turned its 3D data into a rendered scene for each user. UNC researchers also developed "imperceptible structured light," which projects rapidly changing patterns that look like ordinary white light to people but give synchronized cameras surface features to measure on blank areas such as walls. The first tele-immersion demonstration, on May 9, 2000, linked a telecubicle in Chapel Hill with researchers at Advanced Network and Services in Armonk, New York, and at the University of Pennsylvania; Lanier reported a frame rate of 2 to 3 frames per second and up to one second of delay. The VGTC citation in 2013 noted that Fuchs was continuing this work within a multinational telepresence research center with sites at ETH Zurich, NTU Singapore and UNC Chapel Hill.
