I am working on an application which draws maps on a screen. This is
done with using sets of x,y coordinates which are made into polygons and
then drawn in a paintComponent. The user now wants to add elevation (a
"z" component). The question at hand is how to quickly index into a data
structure to find an elevation point based on the mouse location (x,y)
of the screen. Currently, polygon.contains(x,y) is used. I was hoping
that someone might either relate how they might have done something
similar or a pointer to reference. Thanks - Lou
