Beschreibung
intersection_linesintersection_linesIntersectionLinesIntersectionLinesIntersectionLines berechnet den Schnittpunkt von zwei
Geraden, die über jeweils zwei Punkte
(Line1Row1Line1Row1Line1Row1Line1Row1line1Row1,Line1Column1Line1Column1Line1Column1Line1Column1line1Column1) und
(Line1Row2Line1Row2Line1Row2Line1Row2line1Row2,Line1Column2Line1Column2Line1Column2Line1Column2line1Column2)
beziehungsweise
(Line2Row1Line2Row1Line2Row1Line2Row1line2Row1,Line2Column1Line2Column1Line2Column1Line2Column1line2Column1) und
(Line2Row2Line2Row2Line2Row2Line2Row2line2Row2,Line2Column2Line2Column2Line2Column2Line2Column2line2Column2)
definiert werden. Der Schnittpunkt, falls vorhanden,
wird in (RowRowRowRowrow,ColumnColumnColumnColumncolumn) zurückgegeben.
Sind die beiden Geraden identisch, liefert der
Parameter IsOverlappingIsOverlappingIsOverlappingIsOverlappingisOverlapping den Wert 1 zurück, ansonsten wird
der Wert 0 zurückgegeben.
In diesem Fall wird
kein Schnittpunkt in (RowRowRowRowrow,ColumnColumnColumnColumncolumn) zurückgegeben.
Ausführungsinformationen
- Multithreading-Typ: reentrant (läuft parallel zu nicht-exklusiven Operatoren).
- Multithreading-Bereich: global (kann von jedem Thread aufgerufen werden).
- Wird ohne Parallelisierung verarbeitet.
