Hi List! I am recieving Quaternion rotation data from a sensor dress and I want to translate to Euler rotation in degrees. I have been searching on the net and I have found the trackball code http://developer.apple.com/SampleCode/TrackBall/listing9.html and other equations http://www.euclideanspace.com/maths/geometry/rotations/conversions/quaternionToEuler/index.htm.
I am not able to understand any text code. So, is there any patch out there can do the work? It may be able to creat a patch from Apple's the C code. It shows a very usefull app. Thank you!
