Interactive Graphics in Data Processing: Interactive aspects of crystal structure analysis

by Y. Okaya
In demonstrating the advantageous use of graphics in a heuristic approach to problem solving, the deciphering of unknown crystal structures is used as an environment. The interactive graphic console lends concreteness to the crystallographer's abstract perception of three-dimensional structures. This paper describes how the crystallographer uses graphics in determining crystal structure by matching a known spatial molecular model with an experimental crystallographic model and by direct theoretical procedures when no model is available. Also presented are computer rendering techniques that make the man-machine relationship more productive. In conclusion, the author ponders the possibilities of more efficient and productive scientific research through the evolution of computer-aided data libraries.
