Beschreibung
distance_psdistance_psDistancePsDistancePsDistancePs berechnet den minimalen und den maximalen Abstand
zwischen einem Punkt (RowRowRowRowrow,ColumnColumnColumnColumncolumn) und einer Strecke.
Die Strecke wird durch ihre Anfangs- (Row1Row1Row1Row1row1,Column1Column1Column1Column1column1)
und Endkoordinate (Row2Row2Row2Row2row2,Column2Column2Column2Column2column2) beschrieben.
DistanceMaxDistanceMaxDistanceMaxDistanceMaxdistanceMax ist der maximale Abstand zu den beiden
Endpunkten der Strecke.
DistanceMinDistanceMinDistanceMinDistanceMindistanceMin liefert den Abstand senkrecht zur Strecke
(analog zu distance_pldistance_plDistancePlDistancePlDistancePl), falls der Punkt „zwischen“
den Endpunkten liegt. Ansonsten wird der minimale Anstand zu einem
der Endpunkte verwendet.
Ausführungsinformationen
- Multithreading-Typ: reentrant (läuft parallel zu nicht-exklusiven Operatoren).
- Multithreading-Bereich: global (kann von jedem Thread aufgerufen werden).
- Wird ohne Parallelisierung verarbeitet.
