ProjectionTransform

Represents a 3D transform similar to an AffineTransform, but it does not guarantee the preservation of parallel lines. These transforms are used whenever a perspective projection is needed to properly render an item.

Properties

isIdentity

val isIdentity: Boolean

true if this transform is equal to the Identity transform

matrix

val matrix: SquareMatrix<Double>

Functions

equals

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

hashCode

open override fun hashCode(): Int

invoke

open operator fun invoke(polygon: ConvexPolygon): ConvexPolygon

Transforms the given polygon. Note that the resulting polygon is a 2D projection of the transformed points. That is because this transform may map the 2D points of polygon into a set of 3d points.

inline operator fun invoke(point: Point): Vector3D

operator fun invoke(point: Vector3D): Vector3D

operator fun invoke(vararg points: Point): List<Vector3D>

operator fun invoke(vararg points: Vector3D): List<Vector3D>

@JvmName(name = "callPoint")

fun invoke(points: List<Point>): List<Vector3D>

fun invoke(points: List<Vector3D>): List<Vector3D>

Transforms the given points.

times

open operator fun times(other: AffineTransform): ProjectionTransform

open operator fun times(other: ProjectionTransform): ProjectionTransform

Allows transforms to be combined sequentially.

toString

open override fun toString(): String
