*scratches noggin*
Um if my memory serves me correctly from CS2 @ varsity...
If you draw a line either horizontally or vertically and in the process
of "drawing" this line you cross an even number of vertices you are
still inside your polygon. If you cross an uneven number of vertices you
are outside your polygon.
Hope this helps... *evil grin*
Cheers,
Renier

Hi
I am trying to create a polygon in Java. The coordinates
of the polygon is lat/long (geographic coordinates) so it
can go up to quite a few decimal places.
Have anyone ever done something like this? I need to
determine whether this polygon then contain a specific
point (coordinates also in lat/long).
Any help will be appreciated.
