Signature 
fun decompose(): Pair<Pose, Vector3>
Returns
Pair<Pose, Vector3>  A Pair containing the Pose object and the scale Vector3.
determinant ()
Calculates the determinant of this matrix.
Signature 
fun determinant(): Float
Returns
Float  the determinant of the matrix
times ( other )
Multiplies this matrix by another matrix and returns the result.
Signature 
operator fun times(other: Matrix44): Matrix44
Parameters
other: Matrix44  the matrix to multiply by
Returns
Matrix44  the resulting matrix
times ( vector )
Multiplies this matrix by a Vector4 and returns the result.
Signature 
operator fun times(vector: Vector4): Vector4
Parameters
vector: Vector4  the Vector4 to multiply by
Returns
Vector4  the resulting Vector4

Companion Object

Methods

composeFromTRS ( transform , scale )
