DecomposedTransform

  • A type to break down a matrix_float4x4 into its specific transformation attributes / properties (i.e. scale, translation, etc.).

    Instantiate this using: matrix_float4x4.decomposed().

    Note

    Under the hood this does a conversion to represent its contents as matrix_double4x4 which could be expensive when done frequently.
