Trajectory
¶ Bases:
traits.has_traits.HasPrivateTraits
Describes a trajectory from sampled points.
Based on a discrete number of points in space and time, a continuous trajectory is calculated using spline interpolation of positions between samples.

points
= Dict(key_trait = Float, value_trait = Tuple(Float, Float, Float), desc = "sampled positions along the trajectory")¶ Dictionary that assigns discrete time instants (keys) to sampled (x, y, z) positions along the trajectory (values).

tck
= Property()¶ Spline data, internal use.

location
(t, der=0)¶ Returns the positions for one or more instants in time.
Parameters:  t : array of floats
Instances in time to calculate the positions at.
 der : integer
The order of derivative of the spline to compute, defaults to 0.
Returns:  (x, y, z) : tuple with arrays of floats
Positions at the given times; x, y and z have the same shape as t.

traj
(t_start, t_end=None, delta_t=None, der=0)¶ Python generator that yields locations along the trajectory.
Parameters: Returns:  (x, y, z) : tuples of floats
Positions at the desired times are yielded.
