Vector

class Vector(val x: Double, val y: Double, val z: Double)

A three-dimensional vector used for directions, normals, and light calculations.

Unlike Point, a Vector represents a direction and magnitude rather than a position in space. The subtraction Point - Point yields a Vector, and Point + Vector yields a Point.

Parameters

X component of the vector.

Y component of the vector.

Z component of the vector.

Functions

cross

infix fun cross(other: Vector): Vector

Returns the cross product of this vector and other.

dot

infix fun dot(other: Vector): Double

Returns the dot product of this vector and other.

equals

open operator override fun equals(other: Any?): Boolean

hashCode

open override fun hashCode(): Int

magnitude

fun magnitude(): Double

Returns the length (magnitude) of this vector: sqrt(x^2 + y^2 + z^2).

minus

operator fun minus(other: Vector): Vector

Returns the component-wise difference of this vector and other.

normalize

fun normalize(): Vector

Returns a unit vector in the same direction. Throws if magnitude is zero.

plus

operator fun plus(other: Vector): Vector

Returns the component-wise sum of this vector and other.

times

operator fun times(scalar: Double): Vector

Returns this vector scaled by scalar.

toString

open override fun toString(): String

unaryMinus

operator fun unaryMinus(): Vector

Returns this vector with all components negated.
