Returns $true if the two polygons overlap. $false otherwise.
$onpoly(n1,n2,x,y,x,y,...)
- n1 is the number of points in the first polygon
- n2 is the number of points in the second polygon
- The rest of the parameters are the polygon points. If n1 = 5 and n2 = 3, there must be 8 X coordinates and 8 Y coordinates
Example
$onpoly(3,3,1,1,5,5,10,0,2,2,4,4,9,0)
Returns: $true (The two triangles overlap)
