Detailed Description

Implements a trajectory with blends between segments. TODO: Briefly describe how.

Member Function Documentation

ddx()

rw::math::Q ddx ( double  t ) const

inlinevirtual

Acceleration of trajectory at time t.

Returns the acceleration of the trajectory at time t \(\in[startTime(), endTime()]\).

Parameters

t	[in] time between startTime() and endTime()

Returns

Acceleration

Implements Trajectory< rw::math::Q >.

duration()

double duration ( ) const

inlinevirtual

Total duration of the trajectory.

The duration of the Trajectory corresponds to the time it takes to run through it.

If the trajectory is empty, then -1 is returned.

Implements Trajectory< rw::math::Q >.

dx()

rw::math::Q dx ( double  t ) const

inlinevirtual

Velocity of trajectory at time t.

Returns the velocity of the trajectory at time t \(\in[startTime(), endTime()]\).

Parameters

t	[in] time between startTime() and endTime()

Returns

Velocity

Implements Trajectory< rw::math::Q >.

endTime()

double endTime ( ) const

inlinevirtual

Returns the endTime of the trajectory.

The end time equals startTime() + duration().

Returns

The end time

Reimplemented from Trajectory< rw::math::Q >.

getIterator()

virtual rw::trajectory::TrajectoryIterator<T>::Ptr getIterator ( double  dt ) const

inlinevirtual

Returns a bi-directional interator for running through the trajectory.

For some trajectory types it may be significantly more efficient to run through using an iterator, rather than using random access.

Parameters

dt	[in] The default time step used when using the ++ or – operators in the iterator

Pointer to the iterator. The pointer has ownership.

Implements Trajectory< rw::math::Q >.

startTime()

double startTime ( ) const

inlinevirtual

Returns the startTime of the trajectory.

Returns

Start time

Implements Trajectory< rw::math::Q >.

x()

rw::math::Q x ( double  t ) const

inlinevirtual

Position of trajectory at time t.

Returns the position of the trajectory at time t \(\in[startTime(), endTime()]\).

Parameters

t	[in] time between startTime() and endTime()

Returns

Position

Implements Trajectory< rw::math::Q >.
