Constructor & Destructor Documentation

◆ Law_Interpol()

Law_Interpol::Law_Interpol ( )

Constructs an empty interpolative evolution law. The function Set is used to define the law.

Member Function Documentation

◆ Set() [1/2]

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

Defines this evolution law by interpolating the set of 2D 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).

◆ Set() [2/2]

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

Defines this evolution law by interpolating the set of 2D 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. In the second syntax, Dd and Df define the values of the first derivative of the function at its first and last points. 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).
