Hi John,
The simplest way would be to do:
color_map = new ScalarMap(v, Display.RGB);
display.add(color_map);
at display configuration time.
Then in the method where your shape changes, compute the minimum and maximum
radius values, store them in variables min and max, and do:
color_map.setRange(min, max);
If you always want a given radius to be a given color, then instead pick a
constant min and max and apply the setRange once during display configuration
time.
