Spline3

class wpimath.spline.Spline3

Bases: pybind11_object

Represents a two-dimensional parametric spline that interpolates between two points.

@tparam Degree The degree of the spline.

class ControlVector(x: Tuple[float, float], y: Tuple[float, float])

Bases: pybind11_object

Represents a control vector for a spline.

Each element in each array represents the value of the derivative at the index. For example, the value of x[2] is the second derivative in the x dimension.

property x → Tuple[float, float]

The x components of the control vector.

property y → Tuple[float, float]

The y components of the control vector.

coefficients() → numpy.ndarray[numpy.float64[6, 4]]

Returns the coefficients of the spline.

Returns:

The coefficients of the spline.

getFinalControlVector() → wpimath.spline._spline.Spline3.ControlVector

Returns the final control vector that created this spline.

Returns:

The final control vector that created this spline.

getInitialControlVector() → wpimath.spline._spline.Spline3.ControlVector

Returns the initial control vector that created this spline.

Returns:

The initial control vector that created this spline.

getPoint(t: float) → tuple[wpimath.geometry._geometry.Pose2d, wpimath.units.radians_per_meter]

Gets the pose and curvature at some point t on the spline.

Parameters:

t – The point t

Returns:

The pose and curvature at that point.
