forwardExtrapolationDuration

@JsProperty
public double forwardExtrapolationDuration

Gets or sets the amount of time to extrapolate forward before the property becomes undefined. A value of 0 will extrapolate forever. Default: 0

forwardExtrapolationType

@JsProperty
public Integer forwardExtrapolationType

Gets or sets the type of extrapolation to perform when a value is requested at a time after any available samples. Default: ExtrapolationType.NONE()

interpolationAlgorithm

@JsProperty
public InterpolationAlgorithm interpolationAlgorithm

Gets the interpolation algorithm to use when retrieving a value. Default: LinearApproximation

interpolationDegree

@JsProperty
public double interpolationDegree

Gets the degree of interpolation to perform when retrieving a value. Default: 1

numberOfDerivatives

@JsProperty
public boolean numberOfDerivatives

The number of derivatives contained by this property; i.e. 0 for just position, 1 for velocity, etc. Default: false

referenceFrame

public Integer referenceFrame

Gets the reference frame in which the position is defined. Default: ReferenceFrame.FIXED()
