public class RampInterpolatorVector2D extends InterpolatorVector2D
Make a ramp interpolation between two position
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

RampInterpolatorVector2D
public RampInterpolatorVector2D(Vector2D start, Vector2D end, Vector2D vellimits, Vector2D acclimits, double duration)
Construct RampInterpolator starting at start and finishing in end
with velocity limits vellimimts and acceleration limits acclimits. The duration
will be calculated automatically. The start and end velocity and acceleration is zero.
If duration is not achievable given the velocity and acceleration limits then
the duration will be extended.- Parameters:
start
- [in] Start of interpolatorend
- [in] End of interpolatorvellimits
- [in] velocity limitsacclimits
- [in] acceleration limitsduration
- [in] Time it takes to from one end to the other.
