    Natural sounds are complex phenomena because they typically contain a mixture of events localized in time and frequency. Moreover, dependencies exist across different time scales and frequency bands, which are important for proper sound characterization. Historically, acoustical theorists have represented sound in numerous ways. Our research has focused on a granular method of sonic analysis, whic... View full abstract»

    Researchers at Cornell University constructed a simple real-world scene, the Cornell Box, in which they carefully measured the lighting, geometry, and reflectance properties of every surface and duplicated it in a 3D computer graphics model. Using this simple and controlled experimental setup, they were able to make meaningful comparisons between global illumination simulations and photographs of ... View full abstract»

    Physically based modeling is a computer animation technique that simulates dynamic objects to a high degree of realism. Central to the technique is the process of solving a set of differential equations that express laws from classical mechanics. In this article, we introduce a new physically based method for modeling and animating soft deformable objects. View full abstract»

    Every vector space with an inner product has a geometric algebra, whether or not you choose to use it. This article shows how to call on this structure to define common geometrical constructs, ensuring a consistent computational framework. The goal is to show you that this can be done and that it is compact, directly computational, and transcends the dimensionality of subspaces. We do not use geom... View full abstract»

    What if we could visualize and interact with information directly in the context of our surroundings? Our research group is exploring how augmented reality (AR) could someday make this possible. AR integrates a complementary virtual world with the physical world-for example, by using head-tracked see-through head-worn displays to overlay graphics on what we see. Instead of looking back and forth b... View full abstract»

    We face the possibility and, in some cases, the results of acquiring accurate digital representations of our cities. The first challenge is to take data from multiple sources, which are often accurate but incomplete, and weave them together into comprehensive models. Because of the size and extent of the data that we can now obtain, this modeling task is daunting and must be accomplished in a semi... View full abstract»

    Biometrics technology has come a long way from simpler forms of systems security. But are biometrics-based systems more secure or do they simply require crackers to become more proficient at breaking into systems? To recognize your fingerprint requires that a template of your fingerprint actually be present in the system that verifies your access. If you want to pass as somebody else, presumably y...
