Abstract

An increasingly important application of computers is for technical education. In 1984, the Lawrence Livermore National Laboratory (LLNL) initiated a summer program with the objective to promote the use of computer graphics software in education for interactive modeling and display of appropriate problems, and the production of computer-generated movies for displaying physical phenomena. Much of the original effort was devoted to the development of a Device Independent Graphics Library (DIGLIB), i.e. computer graphics software needed for computer-generated film making. Due to the enormous scope of the project, however, many directions for DIGLIB remained unexplored after the LLNL summer project terminated. The efforts documented in this paper were devoted to exploring new directions and creating further enhancements to DIGLIB, such as a facility to capture and replay generated scenes and the addition of a new user interface containing improved graphics primitives and coordinate mapping functions. The enhancements improve DIGLIB's performance as a software interface for creating computer-generated movies.
