Pictx is an interactive program that combines the two programs showtherm and ir-X. Ultimately it can read a temperature output file and display the image on the screen without having the user call two different programs.
Pictx is designed to be run in an X-windows environment since it does call the program ir-X.
The following is an example from an interactive session.
$ pictx This takes a BRL-CAD mged model with a PRISM temperature output file and raytrace and/or display it using X-Windows graphics. Make your selection. 0 - raytrace & store file 1 - raytrace, store, and showtherm file 2 - showtherm file 1 Enter .g file to be raytraced (15 char max). test.veh.g Enter the number of groups to be raytraced. 1 Enter group 0 (25 char max). vehicle
The program showtherm is now being run.
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
The program ir-X is now being run. If option 0 or 1 was used when the name of a file is asked for enter the name of the file that was just stored.
Enter name of file to be read (26 char max) veh.dis Indicate type of color shading to use. 0 - gray 1 - red 2 - black-blue-cyan-green-yellow-white 3 - black-blue-magenta-red-yellow-white 0 Do you wish to create a pix file (0-no, 1-yes)? 0 Zeroing color info array - finished zeroing. Setting up color scale - shades of gray - finished. Reading file - file read. Width: 512 Height: 512 Finding min & max. Minimum: 22.590000 Maximum: 46.830000 Finding pixel bins - found pixel bins. Putting color info in arrays - color info in arrays. $
