Add one or three RealTypes to your data that you
ScalarMap to color (i.e., to RGB, or to Red, Green
and Blue), and give them different values for each
GriddedSet.

There are two ways to stop direct manipulation:
1. call removeReference(), then addReference() without
a direct manipulation DataRenderer.
2. Extend a direct manipulation DataRenderer and override
its drag_direct() method to alow you to disable, as:
class YourRenderer extends DirectManipulationRendererJ3D {
private boolean enable = true;
public void disable() {
enable = false;
}
public void drag_direct(VisADRay ray, boolean first,
int mouseModifiers) {
if (enable) {
super.drag_direct(ray, first, mouseModifiers);
}
}
}

I don't know what problem you are having, and I don't
know much about JPopUp menus anyways.
Cheers,
Bill
