class Interpol from Law inherits BSpFunc from Law
---Purpose: Provides an evolution law that interpolates a set
-- of parameter and value pairs (wi, radi)
uses
Array1OfPnt2d from TColgp
is
Create returns mutable Interpol from Law;
---Purpose: Constructs an empty interpolative evolution law.
-- The function Set is used to define the law.
Set(me : mutable;
ParAndRad : Array1OfPnt2d from TColgp;
Periodic : Boolean from Standard = Standard_False);
---Purpose:
-- 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).
