## DESCRIPTIONS

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.

## EXAMPLE

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.
    		0
    	Enter name of the PRISM output file to be read (26 char max).
    		veh.prm
    	Enter the number of regions in the PRISM file, must be more
    	than eight (not including the background).
    		18
    	Enter name of region # & name file to be read (26 char max).
    		veh.f.rnn
    	Enter name of output file (26 char max).
    		veh.dis
    	Enter the elapsed time to create graphical representation of.
    		4
    	Number of regions (including the background):  19
    	7/19/1984 7.000000:0.000000
    	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).
    	Building directory.
    	File:  test.veh.g
    	Database Title:  test vehicle for use with irprep programs
    		vehicle loaded
    	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
    	Preparation started.

    	Minimum & maximum X:  -3001.000000 - 3714.000000
    	Minimum & maximum Y:  -1350.000000 - 1350.000000
    	Minimum & maximum Z:  0.000000 - 2500.000000
    	Center of bounding sphere:  356.500000, 0.000000, 1250.000000
    	Radius of bounding sphere:  3829.551456
    	Enter multiplication factor for radius.
    		.75
    	Enter grid size.
    		512
    	Enter azimuth & elevation.
    		35 25
    	gridsize:  512 x 512
    	azimuth:  35.000000 degrees
    	elevation:  25.000000 degrees
