3. DESCRIPTION OF PROGRAM OR FUNCTION - CAM was developed for use in analyzing the radiation dose absorbed by man. CAMERA was developed to perform analyses with CAM. Among the capabilities of CAMERA are combining subgeometry models, performing error tests on geometric models, tracing rays through the geometry, placing results on magnetic tape in various forms, collapsing ray-tracing information to areal density distributions, and preparing cross section view plots. Proton dose calculations are performed by direct input of CAMERA areal density results into CCC-118/SIGMA. CAMERA has been used in conjunction with SIGMA to analyze space vehicle shielding effectiveness, as well as for body shielding effectiveness, in space radiation dose studies.

4. METHOD OF SOLUTION - CAM contains some 1,100 unique quadratic surface equations and 2,450 solid regions. The internal body geometry of the organs, voids, bones and bone marrow is explicitly modeled.
The ray tracing routines used in CAMERA are essentially the same as those used in CCC-89/FASTER, CCC-118/SIGMA, and CCC-243/PATCH. Error tests on the geometry model include checking uniqueness of the points specified in the input region descriptions and requiring that each ray traced end on the outer boundary of the system. Erroneous ray tracing results due to overlaps and holes in the model are minimized by a CAMERA feature enabling the code to automatically approximate rays through these erroneous regions. Areal density distributions are obtained by tallying the total ray lengths into logarithmically spaced bins.
Dose point locations in distributed organs such as the bone marrow can be determined by a random sampling option. Rays can be traced either randomly or systematically distributed in solid angle about the dose point.

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM - CAMERA is entirely variable-dimensioned, so that the problem size is limited only by the computer core available. CAM requires 260K octal words of core. CAMERA can be used for small problems with less than 100K.

6. TYPICAL RUNNING TIME - CAMERA traces rays at an average rate of about five rays per second on the CDC 6500 computer.
CAMERA-PC takes about five minutes on an IBM PC/XT under DOS 3.3, using the sample problem included in the package.

CCC-0240/01:

The program was executed at the NEA-DB on a PC/80486, 66 MHz. To run the test case and display the plot (if requested) on the screen required only a few seconds.

11. MACHINE REQUIREMENTS - CAMERA was written to run on a CDC 6500 computer with 400K octal words of core. It should be operable, with minor modifications, on most machines using FORTRAN IV, with at least 100K octal core. It uses tape and disc files for input, output and scratch. In addition to a printer, options may require use of a card punch and an SC4020 plotter.
CAMERA will also run on IBM PC's and compatibles, with or without a math co-processor.

CCC-0240/01:

NEA-DB implemented the program on a DELL 466/L PC/80486 with 66 MHz. - The disk space required by all the source files is about 200 Kbytes. - The disk space required to hold all the object files created at compilation is about 320 Kbytes. - The filesize of the library CAMERA.LIB is 115 Kbytes. - The filesize of the executable CAMERA.EXE using the /EXEPACK option at linking for reducing the size of the executable created, is 253 Kbytes. Otherwise, without the /EXEPACK option, the size of the created executable is 560 Kbytes. -The storage of the 18 man model library files requires about 1.1 MBytes of disk space.

12. PROGRAMMING LANGUAGE(S) USED -
CCC-0240/01: FORTRAN-77 + ASSEMBLER

13. OPERATING SYSTEM UNDER WHICH PROGRAM IS EXECUTED - A FORTRAN IV compiler and a standard SCOPE operating system, with the Stromberg Datagraphics, Inc., SC4020 software package, are required.
For the PC version, the Microsoft FORTRAN Version 5.1 is needed for the FORTRAN sources. For the Assembler routines, Microsoft Assembler Version 5.1 is required.

CCC-0240/01:

CAMERA was run at NEA-DB under MS-DOS 6.2. The FORTRAN source files were compiled using the Microsoft FORTRAN compiler Version 5.10. The Assembly source files were assembled using the Microsoft Macro Assembler MASM Version 6.11. The Microsoft Library Manager Version 3.18 and Linker Version 5.15 were used to create the library CAMERA.LIB and the executable CAMERA.EXE, respectively.
