Remarks

This is an abstract base class and cannot be instantiated directly. Instead, use one of the derived classes as listed in the following table:

PiecewiseConstantCurveRepresents a curve that is piecewise constant.
PiecewiseLinearCurveRepresents a piecewise linear function.
CubicSplineRepresents a natural or clamped cubic spline curve, a piecewise 3rd degree polynomial with smoothness and continuity properties.
