runs the particles program. In this demonstration program, 15 particles are set in
random motion in a cube. When one of the particles touches a boundary of the
cube, it emits a square bubble that inflates to a certain size and then pops.
Generally, these demonstration programs can be exited by typing
clear the screen of graphics "leftovers", type the command gclear.
The IRIS User's Guide documents the IRIS Graphics Library, the software that a
programmer uses to write applications for the IRIS Workstation. In the second
section of that manual, the IRIS Graphics Library, there are a few sample
programs that illustrate how the graphics software is used. On page 2-57 of
that manual, there is a program listing for a program called track. This program
can be compiled and run on the IRIS Workstation. For example,
$ cc track.c -o track -Zg
See cc(1) for information on the C and FORTRAN compilers for the IRIS
Workstation.
After track has been compiled, it can be run.
$ track
A blue box will appear on the screen which can be moved around with the
Mouse. To exit track, press all three Mouse buttons or

5.3 Monitor Adjustment

The Monitor Control Panel on the right side of the Monitor has several knobs
for adjusting the brightness and contrast of the Monitor.
NOTE: Color rendering and stability may drift for the
first 45 minutes after startup.
1. After the Monitor has warmed up, adjust the
knob until the gray raster is barely brighter than the black areas on
the edge of the screen. Lighter brightness settings will impair image
sharpness and color fidelity.
2. For optimum clarity, turn the
(clockwise) setting and then turn it back slightly.
3. If the color purity or convergence appear to be out of adjustment,
hold down the
about 10 seconds and then release it. The image should then
improve noticeably.
