'Dream Team' assembles with goal of capturing, displaying Gigapixel-sized images
DECEMBER 10--An eclectic group of artists and scientists that organizers have dubbed the "dream team" of imaging and visualization gathered at New York University to begin to create a photographic system capable of capturing and displaying a Gigapixel--1 billion pixels--of visual information in a single image.
DECEMBER 10--An eclectic group of artists and scientists that organizers have dubbed the "dream team" of imaging and visualization gathered at New York University (NYU) to begin to create a photographic system capable of capturing and displaying a Gigapixel--1 billion pixels--of visual information in a single image. The first Big Picture Summit, held Dec. 8 and 9, was organized by artist-photographer Clifford Ross and cohosted by Sandia National Laboratories and the Interactive Telecommunications Program at NYU's Tisch School of the Arts. Ross says his goal in bringing together top imaging experts from leading scientific institutions is to bring closer to reality his desire to create a "you are there" photographic experience for those who have not personally witnessed the sublime beauty of natural scenes such as Mt. Sopris in Colorado.
"In the early 15th century, the impulse to render flesh more realistically drove the artist Jan van Eyck to invent oil paint," says Ross. "The same sort of impulse is driving me, except that I'm trying to capture a mountain. Pixels are simply 21st century oil paint."
The scientists have different but complementary goals. Computational scientists at Sandia, a National Nuclear Security Administration lab, believe a display system of the magnitude proposed by Ross will enhance the ability of its scientists to visualize and gain insight from massively complex data sets that can be understood only through human intuition, ranging from supercomputer-generated physics simulations to high-resolution satellite imagery.
"We have a lot in common with an artist like Clifford Ross and his quest to make extremely detailed images that evoke a powerful emotional response," says Carl Diegert, Sandia computational scientist. "We want to understand from an intuitive standpoint what it is that enables viewers to gain insight - for example, a visual metaphor that makes a human viewer comfortable and thus better able to interact with an image. Computer science alone is not likely to invent a means for scientists to intuitively comprehend highly complex problems."
"My own goal is to fill the eye with so much information that it overflows and reaches the human heart," adds Ross. "Art is emotional, but the path is technical, and virtually all the scientists involved in this effort know more about the technical aspects of imaging than I do."
Ross' newly patented R1 camera system (www.cliffordross.com), which broke through the Gigapixel barrier, has achieved some of the highest-resolution single-shot images ever created. (Efforts by other photographers have digitally melded many smaller images taken over a period of time into single sweeping, Gigapixel-sized landscape images.) The quality of the first landscape images created with the R1 --the "Mountain" series--convinced many of the scientists involved in the Summit to join in the effort, says Diegert.
The project has two parts. The first is to design and build a new camera, expanding on concepts embodied in the R1, that can capture a 1 Gpixel of digital information at a speed of 1/15 s or faster. The second part is to create the display system, which Ross likens to building an "electronic Sistine ceiling." It will have 16 times greater data display capabilities than one currently in use at Sandia, among the world's most advanced. The display would provide an overall view of images at a very large scale while allowing viewers to perceive extremely fine detail.
The Summit is expected to result in a concrete agenda and working group, which would then be funded by interested individuals, foundations, corporations, and government agencies with an interest in the practical implications of Ross' quest.
Sandia is a multiprogram laboratory operated by Sandia Corporation, a Lockheed Martin company, for the US Department of Energy's National Nuclear Security Administration. With main facilities in Albuquerque, NM, and Livermore, CA, Sandia has major R&D responsibilities in national security, energy and environmental technologies, and economic competitiveness.
