For the past two decades, our computer graphics activities have involved the development of a wide range of graphic input and display techniques. A number of input meth-ods have been implemented, and progress has been made on a large variety of display routines. Graphics research topics previously investigated include polygon clipping, hidden surface algorithms, texturing, spatial and temporal aliasing problems, geometric modeling, parametric surface descriptions, and color science.
Our current focus of graphics research involves the three-dimensional modeling of very complex environments and algorithms for realistic image synthesis. A modular testbed that is sufficiently flexible to evaluate different modeling and image generation techniques has been created. Laboratory research is now being conducted on light reflection models, methods for determining the interaction between reflecting surfaces, techniques for improving the computational efficiency of ray-tracing and radiosity algorithms, parallel processing strategies, micro-geometry surface modeling, constraint modeling, anti-aliasing strategies, and a host of other topics related to complex modeling and realistic image displays. Application research is being conducted in volume rendering, medical imaging, the development of generic tools for scientific visualization, input software for preliminary architecture design, digital photography, as well as core technologies for multimedia environments.
Most of the research is conducted within the the Program of Computer Graphics, which is a member of the National Science Foundation Science and Technology Center for Computer Graphics and Scientific Visualization. Other participating universities are Brown University, California Institute of Technology, University of North Carolina (Chapel Hill), and the University of Utah.
