IfcSameCartesianPoint

Definition from IAI: The function compares two IfcCartesianPoint's and ensures that they are the same (with an epsilon precision factor).

HISTORY: New function in Release IFC2x Edition 2

EXPRESS specification:

FUNCTION IfcSameCartesianPoint

  LOCAL
    cp1x : REAL := cp1.Coordinates[1];

    cp2y : REAL := cp2.Coordinates[2];
    cp2z : REAL := 0;
  END_LOCAL;

  IF (SIZEOF(cp1.Coordinates) > 2) THEN
    cp1z := cp1.Coordinates[3];
  END_IF;

  IF (SIZEOF(cp2.Coordinates) > 2) THEN
    cp2z := cp2.Coordinates[3];
  END_IF;

  RETURN (IfcSameValue(cp1x,cp2x,Epsilon) AND
          IfcSameValue(cp1y,cp2y,Epsilon) AND
          IfcSameValue(cp1z,cp2z,Epsilon));
