Abstract : This is a FORTRAN-based computer graphics system designed for interactive use on a wide variety of computer graphics terminals. Due to its comprehensive and modular design, GCS provides a simplified easy to learn and easy to use approach to computer graphics, while simultaneously providing a powerful tool which the sophisticated programmer may use for demanding and highly interactive graphical applications. GCS provides compatibility at two distinct levels: (a) Cross-compatibility from one computer system to another; and (b) Cross-compatibility between computer graphics terminals. Cross-compatibility from one terminal to another has been achieved in a manner which is completely transparent to the user. One need no longer be concerned about the problems of 'tailoring' his programs for a given graphical device--GCS provides the maximum capabilities offered by the various terminals in order to satisfy the user's graphical requirements. Device independence provides the user with the option of preparing and debugging his graphics program on a terminal other than the type he may desire for final output--a consideration of paramount importance for installations which may have a limited number of graphical devices available at any given time.
