Description
intersection_linesintersection_linesIntersectionLinesIntersectionLinesIntersectionLines calculates the intersection point of two
lines, which are defined by two of their points
(Line1Row1Line1Row1Line1Row1Line1Row1line1Row1,Line1Column1Line1Column1Line1Column1Line1Column1line1Column1),
(Line1Row2Line1Row2Line1Row2Line1Row2line1Row2,Line1Column2Line1Column2Line1Column2Line1Column2line1Column2), and
(Line2Row1Line2Row1Line2Row1Line2Row1line2Row1,Line2Column1Line2Column1Line2Column1Line2Column1line2Column1),
(Line2Row2Line2Row2Line2Row2Line2Row2line2Row2,Line2Column2Line2Column2Line2Column2Line2Column2line2Column2) respectively.
The intersection point, if it exists, is returned in
(RowRowRowRowrow,ColumnColumnColumnColumncolumn).
If both lines are identical, IsOverlappingIsOverlappingIsOverlappingIsOverlappingisOverlapping returns the
value 1, otherwise 0 is returned. In this case no intersection point is
returned in (RowRowRowRowrow,ColumnColumnColumnColumncolumn).
Execution Information
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.
