1. NAME AND TITLE
PICTURE: Combinatorial Geometry Printer Plotting.
Battelle, Columbus Division, Columbus, Ohio.
Lawrence Livermore National Laboratory, Livermore, California.
3. CODING LANGUAGE AND COMPUTER
Fortran 77; IBM PC or Compatible.
4. NATURE OF PROBLEM SOLVED
Picture generates plots of two-dimensional slices through the three-dimensional geometry described
by the combinatorial geometry (CG) package used in such codes as MORSE and QAD-CG. These
plots are printed on a standard line printer.
5. METHOD OF SOLUTION
Several different ways are available to obtain a two-dimensional slice through the geometry. The
geometry ray tracing capability is tested by forcing the geometry package to execute the routines and
logic of the Monte Carlo random walk or kernel integration algorithms.
6. RESTRICTIONS OR LIMITATIONS
None noted besides those listed in the input description.
7. TYPICAL RUNNING TIME
The sample problems run in a few minutes on the IBM PC.
8. COMPUTER HARDWARE REQUIREMENTS
PICTURE is operable on an IBM PC with 640 K memory. The IBM Professional version requires
an 8087 math coproccessor
9. COMPUTER SOFTWARE REQUIREMENTS
IBM Personal Computer Professional Fortran, Version 1.0, or Microsoft Fortran Version 3.31 is required for compilation.
The code was run at RSIC under PC DOS 3.1.
Appendix B of the CCC-307/QAD-CG manual.
README.DOC file on diskette.
11. CONTENTS OF CODE PACKAGE
Included are the referenced documents and two (360K) DOS diskettes are required for both IBM
and Microsoft versions.
