Functions

abstract fun as2d(): Vector2D

Gets a 2D version of this vector

abstract fun as3d(): Vector3D

abstract infix fun cross(other: Vector3D): Vector3D

Computes the cross-product of the two vectors.

open infix fun distanceFrom(other: Vector2D): Double

Calculates the euclidean distance between two points.

open infix fun distanceFrom(other: Vector3D): Double

Calculates the euclidean distance between two vectors.

abstract operator override fun div(value: Double): Vector2D

abstract operator override fun div(value: Float): Vector2D

abstract operator override fun div(value: Int): Vector2D

Calculates the scalar product of this vector and the inverse of a value.

infix fun Vector3D.interiorAngle(other: Vector3D): Measure<Angle>

Calculate the interior angle between 2 vectors =>angle := cos(α) = a·b / (|a|·|b|).

open override fun magnitude(): Double

Gets the vector's length

open operator fun minus(other: Vector2D): Vector2D

open operator fun minus(other: Vector3D): Vector3D

Calculates the vector difference of two vectors.

abstract fun normalize(): Vector3D

Gets a unit vector pointing in the same direction as this one, if (and only if) the vector's length is not 0. Otherwise, the vector itself is returned.

open operator fun plus(other: Vector2D): Vector2D

open operator fun plus(other: Vector3D): Vector3D

Calculates the vector sum of two vectors.

abstract operator override fun times(value: Double): Vector2D

abstract operator override fun times(value: Float): Vector2D

abstract operator override fun times(value: Int): Vector2D

Calculates the scalar product of this vector and a value.

open operator fun times(other: Vector3D): Double

Computes the dot-product of the two vectors

abstract operator override fun unaryMinus(): Vector2D

Performs a negation of this vector, resulting in a new vector with inverted x and y directions.
