Image map Polygon Algorithm
Posted on 1999-01-22
I'm trying to write the function which tells me whether
an (x,y) point is in a certain polygon?
i already written ones for rectangle & circle but stuck on
the Poligon - the function looks like that:
pointInPolygon(File i_mapFile , double x, double y)
i dont need you to write a code just a way or an algorithm
to find that (x,y) point is in or not the polygon.
a polygon is at least 3 points of lines that are connected togther (0,0)(100,50)(200,30) the first point should be the last and if its not so im adding another connecting point
but thats for another session!
