WiggleInterpolator

class WiggleInterpolator : HeadingInterpolator

Heading interpolator that wraps another interpolator and adds sinusoidal oscillations ("wiggles") while preserving continuity. More specifically, the wiggle function is composed of a sine wave with a quintic spline on either end.

lateinit var parametricCurve: ParametricCurve

Functions

deriv	`fun deriv(displacement: Double): Double` Returns the heading derivative at the specified displacement.
get	`operator fun get(displacement: Double): Double` Returns the heading at the specified displacement.
init	`fun init(parametricCurve: ParametricCurve): Unit` Initialize the interpolator with a parametricCurve.
respectsDerivativeContinuity	`fun respectsDerivativeContinuity(): Boolean` Returns true if the heading interpolator respects derivative continuity at path segment endpoints. That is, the start and end heading derivatives match those of the TangentInterpolator.
secondDeriv	`fun secondDeriv(displacement: Double): Double` Returns the heading second derivative at the specified displacement.

Inherited Functions

end	`fun end(): Double` Returns the end heading.
endDeriv	`fun endDeriv(): Double` Returns the end heading derivative.
endSecondDeriv	`fun endSecondDeriv(): Double` Returns the end heading second derivative.
start	`fun start(): Double` Returns the start heading.
startDeriv	`fun startDeriv(): Double` Returns the start heading derivative.
startSecondDeriv	`fun startSecondDeriv(): Double` Returns the start heading second derivative.
