poly_poly_intersectΒΆ
poly_poly_intersect returns the intersections of two polylines.

rmXY_I1I2 = poly_poly_intersect(rmXY1, rmXY2)
Return Value
rmXY_I1I2 is a matrix with 4 columns:
Wert  Bedeutung 

rmXY_I1I2[1]  xcoordinates of the intersections. 
rmXY_I1I2[2]  ycoordinates of the intersections. 
rmXY_I1I2[3]  Index of the datapoint in rmXY1 closest to the intersection. 
rmXY_I1I2[4]  Index of the datapoint in rmXY2 closest to the intersection. 
It the two polylines to not cross the return value is 0.
Parameters

rmXY1
rmXY1 is a matrix with two columns with data points.
rmXY1[;1]
are xcoordinates andrmXY1[;2]
are the ycoordinates.

rmXY2
rmXY2 is a matrix with two columns with data points.
rmXY1[;2]
are xcoordinates andrmXY2[;2]
are the ycoordinates.
Example
def XYGetIntersection(hData1, hData2)
{
rmXY1 = XYGetData(hData1);
rmXY2 = XYGetData(hData2);
rmXY_I1I2 = poly_poly_intersect(rmXY1, rmXY2);
if (len(rmXY_I1I2) == 1) {
return 0;
}
return rmXY_I1I2[;1,2];
}
