描述
intersection_linesintersection_linesIntersectionLinesIntersectionLinesIntersectionLinesintersection_lines calculates the intersection point of two
lines, which are defined by two of their points
(Line1Row1Line1Row1Line1Row1Line1Row1line1Row1line_1row_1,Line1Column1Line1Column1Line1Column1Line1Column1line1Column1line_1column_1),
(Line1Row2Line1Row2Line1Row2Line1Row2line1Row2line_1row_2,Line1Column2Line1Column2Line1Column2Line1Column2line1Column2line_1column_2), and
(Line2Row1Line2Row1Line2Row1Line2Row1line2Row1line_2row_1,Line2Column1Line2Column1Line2Column1Line2Column1line2Column1line_2column_1),
(Line2Row2Line2Row2Line2Row2Line2Row2line2Row2line_2row_2,Line2Column2Line2Column2Line2Column2Line2Column2line2Column2line_2column_2) respectively.
The intersection point, if it exists, is returned in
(RowRowRowRowrowrow,ColumnColumnColumnColumncolumncolumn).
If both lines are identical, IsOverlappingIsOverlappingIsOverlappingIsOverlappingisOverlappingis_overlapping returns the
value 1, otherwise 0 is returned. In this case no intersection point is
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。
