CurveInterval

class CurveInterval(curve: Curve2, tLo: Double, tHi: Double, pLo: Vec2, pHi: Vec2)(source)

Represents a parametric interval of a 2D curve, defined by a start and end parameter, and their corresponding geometric positions.

The CurveInterval class is used for operations such as splitting, bounding box calculations, and intersection testing within this range of the curve.

Parameters

curve

the curve (Curve2) to which this interval belongs

tLo

the lower bound of the parametric range

tHi

the upper bound of the parametric range

pLo

the 2D point on the curve corresponding to tLo

pHi

the 2D point on the curve corresponding to tHi

Constructors

CurveInterval

constructor(curve: Curve2, tLo: Double, tHi: Double, pLo: Vec2, pHi: Vec2)

Creates a new instance of CurveInterval representing the interval of a curve. It calculates whether the interval is "flat," determines its parameter range, and sets the starting and ending positions of the interval on the curve.

Properties

curve

val curve: Curve2

isFlat

val isFlat: Boolean

pHi

val pHi: Vec2

Represents the 2D point on the curve corresponding to the upper parameter bound (tHi) of the interval.

pLo

val pLo: Vec2

Represents the 2D position corresponding to the lower parametric bound (tLo) of the curve interval.

tHi

val tHi: Double

The upper bound of the parametric range for the curve interval.

tLo

val tLo: Double

The lower bound of the parametric range of a curve interval.

Functions

bounds

fun bounds(): Box2

intersections

fun intersections(c: Intersections.CurveInterval, acc: MutableList<Vec2>)

Computes the intersection points between the current CurveInterval and another provided CurveInterval. The computed intersection points are added to the provided list of Vec2 objects.

intersects

fun intersects(c: Intersections.CurveInterval): Boolean

split

fun split(): Array<Intersections.CurveInterval>

Splits the current curve interval into two sub-intervals.

toString

open override fun toString(): String
