Type members

• init()

  Constructs a default-initialized Transform2D set to IDENTITY.

• init(from: Transform2D)

  Constructs a Transform2D as a copy of the given Transform2D.

• init(rotation: Float, position: Vector2)

  Constructs the transform from a given angle (in radians) and position.

  Constructs the transform from a given angle (in radians), scale, skew (in radians) and position.

• init(xAxis: Vector2, yAxis: Vector2, origin: Vector2)

  Constructs the transform from 3 Vector2 values representing x, y, and the origin (the three column vectors).

• static let flipX: Transform2D

  The Transform2D that will flip something along the X axis.

Instance members

• var origin: Vector2

  The origin vector (column 2, the third column). Equivalent to array index 2. The origin vector represents translation.

• var x: Vector2

  The basis matrix’s X vector (column 0). Equivalent to array index 0.

• var y: Vector2

  The basis matrix’s Y vector (column 1). Equivalent to array index 1.

• subscript(Int64) -> Vector2
• func affineInverse() -> Transform2D

  Returns the inverse of the transform, under the assumption that the basis is invertible (must have non-zero determinant).

• func basisXform(v: Vector2) -> Vector2

  Returns a vector transformed (multiplied) by the basis matrix.

• func basisXformInv(v: Vector2) -> Vector2

  Returns a vector transformed (multiplied) by the inverse basis matrix, under the assumption that the basis is orthonormal (i.e. rotation/reflection is fine, scaling/skew is not).

• func determinant() -> Double

  Returns the determinant of the basis matrix. If the basis is uniformly scaled, then its determinant equals the square of the scale factor.

• func getOrigin() -> Vector2

  Returns the transform’s origin (translation).

• func getRotation() -> Double

  Returns the transform’s rotation (in radians).

• func getScale() -> Vector2

  Returns the scale.

• func getSkew() -> Double

  Returns the transform’s skew (in radians).

• func interpolateWith(xform: Transform2D, weight: Double) -> Transform2D

  Returns a transform interpolated between this transform and another by a given weight (on the range of 0.0 to 1.0).

• func inverse() -> Transform2D

  Returns the inverse of the transform, under the assumption that the transformation basis is orthonormal (i.e. rotation/reflection is fine, scaling/skew is not). Use affineInverse for non-orthonormal transforms (e.g. with scaling).

• func isConformal() -> Bool

  Returns true if the transform’s basis is conformal, meaning it preserves angles and distance ratios, and may only be composed of rotation and uniform scale. Returns false if the transform’s basis has non-uniform scale or shear/skew. This can be used to validate if the transform is non-distorted, which is important for physics and other use cases.

• func isEqualApprox(xform: Transform2D) -> Bool

  Returns true if this transform and xform are approximately equal, by running @GlobalScope.is_equal_approx on each component.

• func isFinite() -> Bool

  Returns true if this transform is finite, by calling @GlobalScope.is_finite on each component.

• func lookingAt(target: Vector2) -> Transform2D

  Returns a copy of the transform rotated such that the rotated X-axis points towards the target position.

• func orthonormalized() -> Transform2D

  Returns the transform with the basis orthogonal (90 degrees), and normalized axis vectors (scale of 1 or -1).

• func rotated(angle: Double) -> Transform2D

  Returns a copy of the transform rotated by the given angle (in radians).

• func rotatedLocal(angle: Double) -> Transform2D

  Returns a copy of the transform rotated by the given angle (in radians).

• func scaled(scale: Vector2) -> Transform2D

  Returns a copy of the transform scaled by the given scale factor.

• func scaledLocal(scale: Vector2) -> Transform2D

  Returns a copy of the transform scaled by the given scale factor.

• func translated(offset: Vector2) -> Transform2D

  Returns a copy of the transform translated by the given offset.

• func translatedLocal(offset: Vector2) -> Transform2D

  Returns a copy of the transform translated by the given offset.
