A graph-theoretic language extension for an interactive computer graphics environment

A programming language extension, AGILE, for the processing of graphs within an interactive computer graphics environment, is defined. The language is intended to be used for expressing and illustrating graph-theoretic algorithms and applications. However it does not deal with the actual drawing or display of graphs; rather one is able to access an existing general-purpose graphics package. The language then is intended to be used, in conjunction with a graphics package, as a tool for the production of more specialised graphics systems: the language allows one to naturally exploit the underlying graph structure found in a wide class of problems, while a graphics environment permits the elegant display of (and interaction with) such representations.AGILE extends the host language, C, by the addition of a graph database, and operators and control structures to manipulate this database. The graph structure is composed of five basic types: nodes, edges, graphs, sets and bugs (references). A general set of operators and tests are provided, including those for entity creation and deletion, node and edge traversal and tests for equality and containment of sets and graphs. Edges may be treated as being either directed or undirected; also multiple edges between nodes and self-loops are allowed. Arbitrary values and properties may be associated with each of the basic types. In particular, since a node may have a graph as value, a graph hierarchy is possible. Graphics primitives are provided by the GPAC graphics system.Three substantial applications have been programmed in the language: a system for producing diagrams of graphs and a class of data structures, a system for animating four algorithms for finding the maximum flow in a network, and a system for animating and making films of systems dynamics models.Several examples of programmes written in AGILE are included.

Generation of interactive displays from FORTRAN using the PDP - 10/LDS-1 computer graphics system

The PDP-10/LDS-1 combination is a powerful and versatile computer graphics system. A package of programs described here permits the generation of displays and interaction with them by means of simple calls from FORTRAN programs. This makes computer graphics available to individuals who know a little FORTRAN but no assembler language. It serves also as a useful introduction to the LDS-1 for experienced programmers who intend to learn the assembler language and to write their own programs Experience with the language has shown that it is learnable quickly by the class of users at which it is aimed. In addition, the same package has been used by more experienced programmers as a powerful research tool in the study of conformations of biological macromolecules, such as proteins, DNA and RNA.
