Hi Dean, if you concatenate multiple transforms the code won't work. For a matrix there exists more than one solution for the angles around X, Y, and Z axis. One solution could be found a tuple of euler anlges, see: http://users.ece.gatech.edu/~slabaugh/personal/research/euler/euler.html I hope

Hi, I am trying (have been trying for a while) how to calculate the angular values around X, Y, and Z from a Matrix3d object. I am trying to echo positional data of a vrml object to the user. I get the Transform3D object from the TransformGroup vrml node and then get the matrix3d object and the
