Found my cam and now ... Cool Fun !!

As a point of interest, I notice that the models REALLY hate going upside down.

As that part of the rotation problem you're having?

Or is it the marker fails to recognise that way?

Or is there no way of knowing at this stage? (NO, I cant post video)


[EDIT] i found this quote deep in the ArToolkit forums. Hope its of some use...
Quote:

The rotation is cleanly represented by for example a quaternion or a 3x3
rotation matrix, not as you suggest by roll, yaw and pitch (also known
as Euler angles). The reason is that Euler angles are not clean is that
it can possibly suffer from an effect that is called the Gimbal lock. If
you need Euler angles anyway (as i did) you can calculate the Euler
angles from a matrix with the code found on this site:
http://www.euclideanspace.com/maths/geometry/rotations/conversions/matrixToEuler/index.htm
Keep in mind that the order of the Euler angles is important for the
calculation, and for where the gimbal lock exactly occurs
