Description
intersection_segmentsintersection_segmentsIntersectionSegmentsIntersectionSegmentsintersection_segments calculates the intersection point of two
line segments, which are defined by their endpoints
(Segment1Row1Segment1Row1Segment1Row1segment1Row1segment_1row_1,Segment1Column1Segment1Column1Segment1Column1segment1Column1segment_1column_1),
(Segment1Row2Segment1Row2Segment1Row2segment1Row2segment_1row_2,Segment1Column2Segment1Column2Segment1Column2segment1Column2segment_1column_2), and
(Segment2Row1Segment2Row1Segment2Row1segment2Row1segment_2row_1,Segment2Column1Segment2Column1Segment2Column1segment2Column1segment_2column_1),
(Segment2Row2Segment2Row2Segment2Row2segment2Row2segment_2row_2,Segment2Column2Segment2Column2Segment2Column2segment2Column2segment_2column_2) respectively.
The intersection point, if it exists, is returned in
(RowRowRowrowrow,ColumnColumnColumncolumncolumn).
If both segments have a part in common, IsOverlappingIsOverlappingIsOverlappingisOverlappingis_overlapping returns the
value 1, otherwise 0 is returned.
In this case the endpoints of the mutual segment are
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.
