intersection_llintersection_llIntersectionLlintersection_llIntersectionLlIntersectionLl (Operator)

Name

intersection_llintersection_llIntersectionLlintersection_llIntersectionLlIntersectionLl — Berechnen des Schnittpunktes zwischen zwei Geraden.

Warnung

intersection_llintersection_llIntersectionLlintersection_llIntersectionLlIntersectionLl ist veraltet und wird nur aus Gründen der Rückwärtskompatibilität zur Verfügung gestellt. Neue Applikationen sollten stattdessen den Operator intersection_linesintersection_linesIntersectionLinesintersection_linesIntersectionLinesIntersectionLines aus dem Kapitel Tools / Geometrie verwenden.

Beschreibung

intersection_llintersection_llIntersectionLlintersection_llIntersectionLlIntersectionLl berechnet die Koordinaten des Schnittpunktes zwischen zwei Geraden. Als Eingabe werden je zwei Punkte auf den Geraden erwartet (RowA1RowA1RowA1RowA1RowA1rowA1,ColumnA1ColumnA1ColumnA1ColumnA1ColumnA1columnA1, RowA2RowA2RowA2RowA2RowA2rowA2,ColumnA2ColumnA2ColumnA2ColumnA2ColumnA2columnA2) und (RowB1RowB1RowB1RowB1RowB1rowB1,ColumnB1ColumnB1ColumnB1ColumnB1ColumnB1columnB1, RowB2RowB2RowB2RowB2RowB2rowB2,ColumnB2ColumnB2ColumnB2ColumnB2ColumnB2columnB2). Das Ergebnis wird dann in RowRowRowRowRowrow und ColumnColumnColumnColumnColumncolumn übergeben. Falls die Geraden parallel zueinander sind, sind die Werte von RowRowRowRowRowrow und ColumnColumnColumnColumnColumncolumn undefiniert und IsParallelIsParallelIsParallelIsParallelIsParallelisParallel hat den Wert 1. Andernfalls liefert IsParallelIsParallelIsParallelIsParallelIsParallelisParallel den Wert 0.

Achtung

Falls die Geraden parallel zueinander sind, dann sind die Werte von RowRowRowRowRowrow und ColumnColumnColumnColumnColumncolumn undefiniert.
