Abstract:

The objective the Graphics program at Lincoln Laboratory is the development of computer hardware and programs which will enable users to work on-line in an interactive mode employing graphical techniques for the input, manipulation and representation of graphical data. The work includes the investigation of problems related to using a time-shared computer, such as TX-2, for graphics, and the design of general-purpose system programs to provide graphics capability for a variety of scientific, military and control problems. During the last reporting period, the following has been accomplished A general-purpose fron-tend system has been designed based on the VITAL system. VITAL itself has been expanded to allow a compiler to control the scanning of a source program and outputting of messages. An ALGOL-like language, LABGOL, has been implemented with the additon of means for building and manipulating a store of explicit relations between objects and their attributes, a new language, LEAP, has also been specified. The new hybrid conic generator has been operated successfully on-line.
