描述
intersection_segment_lineintersection_segment_lineIntersectionSegmentLineIntersectionSegmentLineIntersectionSegmentLineintersection_segment_line calculates the intersection point of a
segment and a line. The segment is defined by its endpoints
(SegmentRow1SegmentRow1SegmentRow1SegmentRow1segmentRow1segment_row_1,SegmentColumn1SegmentColumn1SegmentColumn1SegmentColumn1segmentColumn1segment_column_1) and
(SegmentRow2SegmentRow2SegmentRow2SegmentRow2segmentRow2segment_row_2,SegmentColumn2SegmentColumn2SegmentColumn2SegmentColumn2segmentColumn2segment_column_2). The line is defined by
the two points (LineRow1LineRow1LineRow1LineRow1lineRow1line_row_1,LineColumn1LineColumn1LineColumn1LineColumn1lineColumn1line_column_1) and
(LineRow2LineRow2LineRow2LineRow2lineRow2line_row_2,LineColumn2LineColumn2LineColumn2LineColumn2lineColumn2line_column_2).
The intersection point, if it exists, is returned in
(RowRowRowRowrowrow,ColumnColumnColumnColumncolumncolumn).
If the segment and the line have a part in common, IsOverlappingIsOverlappingIsOverlappingIsOverlappingisOverlappingis_overlapping
returns the value 1, otherwise 0 is returned.
In this case the endpoints of the mutual
segment are returned in (RowRowRowRowrowrow,ColumnColumnColumnColumncolumncolumn).
执行信息
- 多线程类型：可重入（与非独占算子并行运行）。
- 多线程作用域：全局（可从任何线程调用）。
- 未采用并行化处理。
