java.lang.Object

org.robwork.sdurw_trajectory.InterpolatorVector3D

org.robwork.sdurw_trajectory.RampInterpolatorVector3D

public class RampInterpolatorVector3D
extends InterpolatorVector3D

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

Constructor Detail

RampInterpolatorVector3D

public RampInterpolatorVector3D(long cPtr,
                                boolean cMemoryOwn)

RampInterpolatorVector3D

public RampInterpolatorVector3D(Vector3D start,
                                Vector3D end,
                                Vector3D vellimits,
                                Vector3D 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 interpolator

end - [in] End of interpolator

vellimits - [in] velocity limits

acclimits - [in] acceleration limits

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

RampInterpolatorVector3D

public RampInterpolatorVector3D(Vector3D start,
                                Vector3D end,
                                Vector3D vellimits,
                                Vector3D acclimits)

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 interpolator

end - [in] End of interpolator

vellimits - [in] velocity limits

acclimits - [in] acceleration limits
