nose — test geomview's picking facility
Nose is a geomview module which tests the geomview picking facility.
Nose has no panel of its own. You invoke it by selecting the "Nose" line in the APPLICATIONS browser. Once invoked, nose waits for you to click the right mouse button with the cursor over some object in a geomview camera window. It then draws a little box on the spot where you clicked. If the picked spot is along an edge, it also draws a pair of boxes at the endpoints of the edge, and a line segment along the edge. If the picked spot is on a vertex, the box is a different color.
Nose is not necessarily intended to be a useful program. It is just a simple example of how an external program can find out about and make use of geomview pick events.
