quatdiff c code?
I met with Andy B. today and he pointed me to the quatdiff function as a potential single metric solution to the error calculation. I know the function is available through Vizard but I'd like to...

Please
Yes, it would be helpful if you could offer a script for calculating the vector/rotation. Fewer variables makes the analysis much easier.
Thank you.

Yes
Yes, indeed! There are likely to be multiple euler sets that yield the same displacement errors. Sorry for being so bone-headed.:D

another hole
I don't mean to be a bother but the modified script still yields a non-unique solution. For example, both of the following sets of eulers yield the same solution:
euler1 = [30,90,0]
euler2 =...

3 vectors?
Is the non-unique solution due to the selection of 90 degrees as the pitch angle? Ultimately, I need a unique solution. Is it reasonable to assume that this might be addressed by calculating the...

non-unique solution
Jerry pointed out that the script doesn't always give a unique solution. For example, both of the following sets of eulers give the same forward_diff and up_diff solution, which is (90, 90).

Elapse timer
I'm trying to build an elapse timer that will record the duration of a user event. I'm using the time.clock() function within a mousedown event to call the start time but I haven't been able to zero...
