Functions

open fun bounds(): Box2

Computes the bounding box of the curve by evaluating its start, end, and inflection points.

abstract fun direction(t: Double): Vec2

open fun end(): Vec2

abstract fun endpoints(start: Vec2, end: Vec2): Curve2

abstract fun inflections(): DoubleArray

Computes the parametric points along the curve where the curve's curvature changes sign.

open fun intersections(c: Curve2): Array<Vec2>

abstract fun isFlat(epsilon: Double): Boolean

abstract fun length(): Double

abstract fun nearestPoint(p: Vec2): Double

abstract fun position(t: Double): Vec2

open fun range(interval: Interval): Curve2

open fun range(tMin: Double, tMax: Double): Curve2

abstract fun reverse(): Curve2

Reverses the direction of the curve, swapping its start and end points.

abstract fun signedArea(): Double

Given a ring of curves, the sum of area() will be the area enclosed by that ring. For clockwise rings, the sum will be negative, for counter-clockwise rings it will be positive.

abstract fun split(t: Double): Array<Curve2>

open fun split(unsafeTs: DoubleArray): Array<Curve2>

open fun start(): Vec2

abstract fun subdivide(error: Double): Array<Vec2>

abstract fun transform(m: Matrix3): Curve2
