showtherm — ray-traces a BRL-CAD geometry file and as a region is hit the temperature of that region is looked up in a temperature output file
showtherm is an interactive program that ray-traces a BRL-CAD geometry file that does not include air and as a region is hit the temperature is looked up in a temperature output file. This file may be either a PRISM temperature output file or a generic temperature output file.
showtherm then creates an output file that is readable by Analyzer2 (an X-windows program written by Glen Durfee), ir-X, or ir-sgi. These programs will graphically showtherm the image with temperatures being represented by different colors.
The following is an example from an interactive session.
$ showtherm test.veh.g vehicle
Type of output file to be read 0=>PRISM, 1=>generic.
Enter name of the PRISM output file to be read (26 char max).
Enter the number of regions in the PRISM file, must be more
than eight (not including the background).
Enter name of region # & name file to be read (26 char max).
Enter name of output file (26 char max).
Enter the elapsed time to create graphical representation of.
Number of regions (including the background): 19
Prism out file read.
Region # & name file opened.
The number of regions read from the output file and the region # & name
file was the same, 18 (does not include background in number).
Database Title: test vehicle for use with irprep programs
The number of regions read from the output
file, the region # & name file, and the .g
file are all equal. The number of regions
read, including the background is 19
