1. NAME AND TITLE
CGS: Common Graphics System, Version 11.4.
Los Alamos National Laboratory, Los Alamos, New Mexico.
3. CODING LANGUAGE AND COMPUTER
Fortran 77, and C. Computers: Cray, IBM RISC 6000, Dec workstations, Sun workstations and others with UNIX operating systems, VAX under VMS.
4. NATURE OF PROBLEM SOLVED
CGS is a library of Fortran subroutines that provides general purpose graphics.
5. METHOD OF SOLUTION
The CGS subroutines are divided into three functional groups. The viewing subroutines define the plotting limits and placement of the graphics output on the graphics view surfaces. The output subroutines generate graphics images as well as prepare a surface for plotting. The attribute subroutines control the appearance of the graphics output.
6. RESTRICTIONS OR LIMITATIONS
This release of CGS Version 11.4 requires the X11 window system. Many UNIX operating systems come bundled with X11. If X11 is not available on your system you may contact:
MIT Software Distribution Center
Technology Licensing Office
77 Massachusetts Avenue
Cambridge, MA 02139
phone: (617) 258-8330
7. TYPICAL RUNNING TIME
The time is dependent on the complexity of the plot. It ranges from a few seconds to several minutes.
8. COMPUTER HARDWARE REQUIREMENTS
CGS runs on most UNIX based computers like Cray, IBM RISC 6000, Sun Sparcstations, Dec workstations, Hewlett Packard workstations, and VAX computers running VMS.
9. COMPUTER SOFTWARE REQUIREMENTS
Fortran-77 and C compilers are required. The code was run at RSIC on the IBM RISC 6000 under AIX 3.2 and X11 window subsystem and also on Sun Sparcstation under Sun OS 4.1.3 and X11.
