Point-Based Graphics /  Volume Graphics 2006 - Keynote

Marc Levoy, Stanford University: Where does volume and point data come from?

From borehole tomography in geophysics to confocal microscopy in the biological sciences, the use of computers during image formation has revolutionized our ability to observe the natural and manmade worlds. Many of these imaging methods produce volume or point data. While the volume graphics community has done an admirable job displaying medical data, and the point graphics community has done similarly well with dense polygon meshes, many other scientific disciplines are going hungry for lack of good visualization tools. In this talk, I will briefly survey the use of computational imaging in a number of core sciences, including physics, chemistry, biology, astronomy, and geology.
I will argue that as visualization researchers we must learn each domain and work closely with its discipline scientists. I will also argue that we must understand the domain's acquisition technologies, including its limitations and special opportunities. Finally, I will argue that we can best help these scientists not by displaying their polished volume and point datasets, but by aiding them to visualize and analyze the data acquisition process itself.

Marc Levoy is a Professor of Computer Science and Electrical Engineering at Stanford University. He received his PhD in Computer Science from the University of North Carolina in 1989. In the 1970's Levoy worked on computer animation, developing an early computer-assisted cartoon animation system. In the 1980's he worked on volume rendering, a family of techniques for displaying sampled three-dimensional functions, such as CT and MR data. In the 1990's he worked on technology and algorithms for 3D scanning. This led to the Digital Michelangelo Project, in which he and a team of researchers spent a year in Italy digitizing the statues of Michelangelo using laser rangefinders. His current interests include light field sensing and display, computational imaging, and digital photography. Levoy received the NSF Presidential Young Investigator Award in 1991 and the SIGGRAPH Computer Graphics Achievement Award in 1996 for his work in volume rendering.
