public class LinearInterpolatorVector2D_f
extends InterpolatorVector2D_f

Make a linear interpolation between to position

Given a start \mathbf{s}, end \mathbf{e} and duration d
the interpolation is implemented as \mathbf{x}(t)=\mathbf{s} + (\mathbf{e}-\mathbf{s})*t/d.

The template argument given needs to support addition with the "+" operator
and scaling with a double using the "*" operator.

For use with a rw::math::Transform3D see the template specialization

                                    boolean cMemoryOwn)

LinearInterpolatorVector2D_f

public LinearInterpolatorVector2D_f(Vector2Df start,
                                    Vector2Df end,
                                    double duration)

Construct LinearInterpolator starting a start and finishing in end
and taking duration time.

If duration <= 0 an exception is thrown

Parameters:

start - [in] Start of interpolator

end - [in] End of interpolator

duration - [in] Time it takes to from one end to the other.
