intersection_segment_lineintersection_segment_lineIntersectionSegmentLineIntersectionSegmentLine (Operator)
Name
intersection_segment_lineintersection_segment_lineIntersectionSegmentLineIntersectionSegmentLine — Calculate the intersection point of a segment and a line
Signature
Herror intersection_segment_line(double SegmentRow1, double SegmentColumn1, double SegmentRow2, double SegmentColumn2, double LineRow1, double LineColumn1, double LineRow2, double LineColumn2, double* Row, double* Column, Hlong* IsOverlapping)
Herror T_intersection_segment_line(const Htuple SegmentRow1, const Htuple SegmentColumn1, const Htuple SegmentRow2, const Htuple SegmentColumn2, const Htuple LineRow1, const Htuple LineColumn1, const Htuple LineRow2, const Htuple LineColumn2, Htuple* Row, Htuple* Column, Htuple* IsOverlapping)
void IntersectionSegmentLine(const HTuple& SegmentRow1, const HTuple& SegmentColumn1, const HTuple& SegmentRow2, const HTuple& SegmentColumn2, const HTuple& LineRow1, const HTuple& LineColumn1, const HTuple& LineRow2, const HTuple& LineColumn2, HTuple* Row, HTuple* Column, HTuple* IsOverlapping)
static void HOperatorSet.IntersectionSegmentLine(HTuple segmentRow1, HTuple segmentColumn1, HTuple segmentRow2, HTuple segmentColumn2, HTuple lineRow1, HTuple lineColumn1, HTuple lineRow2, HTuple lineColumn2, out HTuple row, out HTuple column, out HTuple isOverlapping)
Description
intersection_segment_lineintersection_segment_lineIntersectionSegmentLineIntersectionSegmentLineIntersectionSegmentLine calculates the intersection point of a
segment and a line. The segment is defined by its endpoints
(SegmentRow1SegmentRow1SegmentRow1SegmentRow1segmentRow1,SegmentColumn1SegmentColumn1SegmentColumn1SegmentColumn1segmentColumn1) and
(SegmentRow2SegmentRow2SegmentRow2SegmentRow2segmentRow2,SegmentColumn2SegmentColumn2SegmentColumn2SegmentColumn2segmentColumn2). The line is defined by
the two points (LineRow1LineRow1LineRow1LineRow1lineRow1,LineColumn1LineColumn1LineColumn1LineColumn1lineColumn1) and
(LineRow2LineRow2LineRow2LineRow2lineRow2,LineColumn2LineColumn2LineColumn2LineColumn2lineColumn2).
The intersection point, if it exists, is returned in
(RowRowRowRowrow,ColumnColumnColumnColumncolumn).
If the segment and the line have a part in common, IsOverlappingIsOverlappingIsOverlappingIsOverlappingisOverlapping
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.
