Method Details

parameterize

public static List<PoseWithCurvature> parameterize(Spline spline)

Parametrizes the spline. This method breaks up the spline into various arcs until their dx, dy, and dtheta are within specific tolerances.

Parameters:

spline - The spline to parameterize.

Returns:

A list of poses and curvatures that represents various points on the spline.

Throws:

SplineParameterizer.MalformedSplineException - When the spline is malformed (e.g. has close adjacent points with approximately opposing headings)

parameterize

public static List<PoseWithCurvature> parameterize(Spline spline, double t0, double t1)

Parametrizes the spline. This method breaks up the spline into various arcs until their dx, dy, and dtheta are within specific tolerances.

Parameters:

spline - The spline to parameterize.

t0 - Starting internal spline parameter. It is recommended to use 0.0.

t1 - Ending internal spline parameter. It is recommended to use 1.0.

Returns:

A list of poses and curvatures that represents various points on the spline.

Throws:

SplineParameterizer.MalformedSplineException - When the spline is malformed (e.g. has close adjacent points with approximately opposing headings)
