AffineTransformationMatrix1

data class AffineTransformationMatrix1(val m00: Double, val m01: Double) : Transformer<Vec1> (source)

Affine transformation matrix for one-dimensional Euclidean vectors.

Constructors

AffineTransformationMatrix1

constructor(m00: Double, m01: Double)

Types

object Companion

Properties

val m00: Double

The scaling factor for the x-coordinate.

val m01: Double

The translation factor for the x-coordinate.

Functions

open override fun apply(obj: Vec1): Vec1

Applies the transformation to a point.

fun determinant(): Double

Computes the determinant of the affine transformation matrix. In one-dimensional space, the determinant is simply the scaling factor (m00).

fun eq(other: AffineTransformationMatrix1, equivalence: DoubleEquivalence = DEFAULT_DOUBLE_EQUIVALENCE): Boolean

Tests if two affine transformation matrices are approximately equal.

open override fun inverse(): AffineTransformationMatrix1

Get the inverse of this transformation.

preserveOrientation

open override fun preserveOrientation(): Boolean

Checks if the transformation preserves the orientation of points. For example: In 3D space, a translation preserves orientation, while a reflection does not.

operator fun times(other: AffineTransformationMatrix1): AffineTransformationMatrix1

Multiplies two affine transformation matrices. In one-dimensional space, this is a simple multiplication of the scaling factors and an addition of the translation factors.

fun toArray(): DoubleArray

Converts the transformation matrix to an array representation. The array is structured in row-major order.

open override fun toString(): String
