Functions

open override fun apply(obj: Vec3): Vec3

Applies the transformation to a point.

fun determinant(): Double

Returns a string representation of the transformation matrix.

fun eq(other: AffineTransformationMatrix3, equivalence: DoubleEquivalence = DEFAULT_DOUBLE_EQUIVALENCE): Boolean

Tests if two affine transformation matrices are approximately equal.

open override fun inverse(): AffineTransformationMatrix3

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.

fun toArray(): DoubleArray

Get the array representation of the transformation matrix.
