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.
Which is the best data structure to use to look up an x,y point in order
to get a z point (elevation). If the exact x,y is not present then
return the closest.
I was hoping that someone might either relate how they might have done
something similar or a pointer to reference. Thanks - Lou
