Abstract : This report presents an overview of the subject of computer graphics and its potential contribution in the analysis of scientific/engineering data. It is directed to the engineer familiar with computer modeling and analysis but not with computer visualization techniques important in treating complex results. Standard graphics hardware and software are discussed, with emphasis on recent advances made by the computer graphics industry. Covered are diverse technical applications including two- and three-dimensional dynamic simulations and the software techniques employed to 'visualize' the results of these calculations. Realism--employing shading algorithms to make artificial graphics appear real and lifelike--is investigated. An approach to writing a complete multidimensional scientific animation graphics package--SCAN--is detailed. The challenge of dealing with the voluminous data generated by three-dimensional numerical modeling encouraged the development of such a program. The objectives, architecture, and results are briefly described; and future trends in computer graphics and their immediate impact on existing computer analysis are explored.
