GRAFTRAN: Graphic Extensions to FORTRAN.
David Elkins, Edward J. Wolf · Defense Technical Information Center (DTIC) · 1972
The paper describes a computer graphics language which can be used to easily display complex structures on a medium scale computer system, such as the XDS 9300/AGT-10 complex at the Naval Postgraduate School. GRAFTRAN (Graphic Extensions to FORTRAN) provides the full capabilities of FORTRAN and includes features that represent a cross-section of operations which are used in present day computer graphics systems. The user is completely isolated from the mechanism to construct and display an image and the manipulation of the data involved. The paper also includes a survey of languages and data structures currently used in graphical applications, and an example GRAFTON program. (Author)
