> Hi all, I want to use J3D to visualize the results of a physics
simulation about the attitude control of a satellite.I compute the
positions and the orientations of the satellite in a geocentric
coordinate systemwhere the z-axis is vertical (it is the y-axis in
the 3D space). I solved that problems with the positions by using
the matrix : 1 0 00 0 10 1 0 How can I do the same thing with
quaternions ?I tried the following matrix but it does'nt look
good: 1 0 0 00 0 1 00 1 0 00 0 0 1 THanks for your help.
