Beschreibung
distance_sldistance_slDistanceSlDistanceSlDistanceSl berechnet den minimalen und den maximalen
orthogonalen Abstand zwischen einer Strecke und einer Geraden.
Als Eingabe werden die Koordinaten der Strecke
(RowA1RowA1RowA1RowA1rowA1,ColumnA1ColumnA1ColumnA1ColumnA1columnA1,RowA2RowA2RowA2RowA2rowA2,ColumnA2ColumnA2ColumnA2ColumnA2columnA2)
und der Geraden
(RowB1RowB1RowB1RowB1rowB1,ColumnB1ColumnB1ColumnB1ColumnB1columnB1,RowB2RowB2RowB2RowB2rowB2,ColumnB2ColumnB2ColumnB2ColumnB2columnB2)
erwartet. Das Ergebnis, d.h. minimaler und maximaler Abstand,
wird dann im Parameter DistanceMinDistanceMinDistanceMinDistanceMindistanceMin und DistanceMaxDistanceMaxDistanceMaxDistanceMaxdistanceMax
übergeben. Falls sich die beiden Strecken
schneiden, dann ist DistanceMinDistanceMinDistanceMinDistanceMindistanceMin gleich Null.
Ausführungsinformationen
- Multithreading-Typ: reentrant (läuft parallel zu nicht-exklusiven Operatoren).
- Multithreading-Bereich: global (kann von jedem Thread aufgerufen werden).
- Wird ohne Parallelisierung verarbeitet.
