Hi, as matrix multiplication isn't cummutative and any homogenous matrix of transform3D can be made of arbitrary successive mutlplications, IMHO you cannot extract orientation by interpreting the matrix elements as an multiplication of predefined sin and/or cos-functions. This will work only in spcial cases like rotation around x-axis. But you can define an inital view direction, i.e. (0,0,-1) or something else, apply the transformation an take the euler angles from the resulting vector as your new view direction.
