RSIC CODE PACKAGE PSR-242

1. NAME AND TITLE
SABRINA 3.54: Three-Dimensional Geometry Visualization Code System.

2. CONTRIBUTOR
Radiation Transport Group, Los Alamos National Laboratory, Los Alamos, New Mexico.

3. CODING LANGUAGE AND COMPUTER
Fortran 77; ANSI C. Version 3.54 runs on IBM, SUN, DEC, Apollo, Hewlett Packard, and 
Silicon Graphics workstations; Vax; and Cray (P00242/MFMWS/02).

4. NATURE OF PROBLEM SOLVED
SABRINA is an interactive, three-dimensional, geometry-modeling code system, primarily 
for use with CCC-200/MCNP. SABRINA's capabilities include creation, visualization, and 
verification of three-dimensional geometries specified by either surface- or body-base 
combinatorial geometry; display of particle tracks as calculated by MCNP; and volume 
fraction generation. The November 1993 update was the initial release of SABRINA 3.54 
and was a complete replacement of the RSICC package. Newer releases (including a Windows
version) are commercially marketed by White Rock Science http://www.whiterockscience.
com/order.html. For more information, follow the SABRINA link under Software Servers 
from RSICC's home page.

5. METHOD OF SOLUTION
Rendering is performed by ray tracing or an edge and intersection algorithm. Volume 
fraction calculations are made by ray tracing.

6. RESTRICTIONS OR LIMITATIONS
A graphics display with X Window capability is required.

7. TYPICAL RUNNING TIME
The time required depends on the complexity of the geometry model, resolution, and the 
size of the display window. Most of the standard SABRINA examples take from a few 
seconds to a few minutes.

8. COMPUTER HARDWARE REQUIREMENTS
Runs on IBM, SUN, DEC, Apollo, Hewlett Packard, and Silicon Graphics workstations 
running UNIX operating systems, Vax computers running ULTRIX and Cray computers running 
UNICOS. A graphics display with X Window capability is required.

9. COMPUTER SOFTWARE REQUIREMENTS
RSICC's version of Sabrina was developed in 1993. Modifications are required to run on 
newer computer systems. A UNIX operating system, Fortran 77 compiler, and ANSI C 
compiler are required. Optionally, PVM version 3.0 or higher for the distributed version;
PostScript printer or viewer for disposal of hardcopy files may be used. SABRINA was 
tested at RSIC on an IBM RISC 6000 Model 550 under AIX 3.2.5 using the xlf FORTRAN 
compiler Version 2.3; SABRINA was also tested on a Sun Sparcstation 2 under SunOS 4.2, 
and SUN FORTRAN 1.4, OPENWIN Version 3.

11. CONTENTS OF CODE PACKAGE
The package includes source directory, including makefiles and a PVM subdirectory, 
sabhelp file, examples directory, and PostScript pages of manual transmitted in tar 
format on either DC 6150 (150 MB), 4 mm DAT (2 or 4 GB), or 8 mm (2.3 GB) cartridge 
tapes. 

12. DATE OF ABSTRACT
April 1987, revised August 1989, December 1993, and May 1994.
