Constructor & Destructor Documentation

Law_Interpol::Law_Interpol ( )

 Constructs an empty interpolative evolution law. <br>

The function Set is used to define the law.

Member Function Documentation

void Law_Interpol::Set ( const TColgp_Array1OfPnt2d ParAndRad,
const Standard_Boolean  Periodic = Standard_False 
)

  Defines this evolution law by interpolating the set of 2D <br>

points ParAndRad. The Y coordinate of a point of
ParAndRad is the value of the function at the parameter
point given by its X coordinate.
If Periodic is true, this function is assumed to be periodic.
Warning

  • The X coordinates of points in the table ParAndRad
    must be given in ascendant order.
  • If Periodic is true, the first and last Y coordinates of
    points in the table ParAndRad are assumed to be
    equal. In addition, with the second syntax, Dd and Df
    are also assumed to be equal. If this is not the case,
    Set uses the first value(s) as last value(s).
void Law_Interpol::Set ( const TColgp_Array1OfPnt2d ParAndRad,
