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 methods 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, parallel processing strategies, perceptual studies, micro-geometry surface modeling, motion control, dynamics, constraint modeling, anti-aliasing strategies, and a host of other topics related to complex modeling and realistic image displays. New application research is being started in volume rendering and medical imaging, digital photography, animation, and the development of generic tools for scientific visualization, as well as core technologies for multi-media environments.

Most of the research is conducted within the facilities of the Program of Computer Graphics, which is a member of the new 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.
