func fromArdkToARKit() -> simd_float4x4

Convert from ARDK coordinates to ARKit coordinates.

The conversion from ARDK to ARKit is a 180º rotation about the x-axis

fromARKitToArdkTransform()​

func fromARKitToArdkTransform() -> ARDK_Transform

Convert this transform to an ARDK_Transform structure.

flatten()​

func flatten() -> [Float]

Flattens the matrix into a column-major array of 16 floats.
