I have a Quaternion that has rotations in it. I can use it to rotate points and stuff, no comes a problem I have to UNROTATE a points useing this quateraion in the same way as If I were to rotate a point around the x axis by 90 degrees I would UNROTATE it with rotate around the x axis by -90 degrees. Is there any way I can find this Reverse Quaternion?? Or do I have to make the reverse quateraion with the info about the rotations before hand?? Thanks, Xero-X2

Well if that google search provided me with anything it was that the thing I was looking for the Inverse so I looked in the Articles and Resources for it and found it is the equvilent to conjugateing the quateraion so there you have it. My question has been answered. Thanks.
