Name
intersection_llintersection_llIntersectionLlIntersectionLl — Berechnen des Schnittpunktes zwischen zwei Geraden.
Warnung
intersection_llintersection_llIntersectionLlIntersectionLlIntersectionLl ist veraltet und wird nur aus Gründen
der Rückwärtskompatibilität zur Verfügung gestellt. Neue
Applikationen sollten stattdessen den Operator intersection_linesintersection_linesIntersectionLinesIntersectionLinesIntersectionLines
aus dem Kapitel Tools / Geometrie verwenden.

Beschreibung
intersection_llintersection_llIntersectionLlIntersectionLlIntersectionLl berechnet die Koordinaten des
Schnittpunktes zwischen zwei Geraden.
Als Eingabe werden je zwei Punkte auf den Geraden erwartet
(RowA1RowA1RowA1RowA1rowA1,ColumnA1ColumnA1ColumnA1ColumnA1columnA1,
RowA2RowA2RowA2RowA2rowA2,ColumnA2ColumnA2ColumnA2ColumnA2columnA2) und
(RowB1RowB1RowB1RowB1rowB1,ColumnB1ColumnB1ColumnB1ColumnB1columnB1,
RowB2RowB2RowB2RowB2rowB2,ColumnB2ColumnB2ColumnB2ColumnB2columnB2).
Das Ergebnis wird dann in RowRowRowRowrow und ColumnColumnColumnColumncolumn
übergeben.
Falls die Geraden parallel zueinander sind, sind die Werte von
RowRowRowRowrow und ColumnColumnColumnColumncolumn undefiniert und IsParallelIsParallelIsParallelIsParallelisParallel
hat den Wert 1. Andernfalls liefert IsParallelIsParallelIsParallelIsParallelisParallel den Wert 0.
Achtung
Falls die Geraden parallel zueinander sind,
dann sind die Werte von RowRowRowRowrow und
ColumnColumnColumnColumncolumn undefiniert.
Ausführungsinformationen
- Multithreading-Typ: reentrant (läuft parallel zu nicht-exklusiven Operatoren).
- Multithreading-Bereich: global (kann von jedem Thread aufgerufen werden).
- Wird ohne Parallelisierung verarbeitet.
