Hello all,
I've searched in the mailing list and the doc file, and I can't find
more info about arMulti.h and its data structure. I looked at
paddleExample and multiExample, but I'm still not sure.

Can somebody please point me to a doc about arMulti.
If not, these are my questions:

in arMulti.h there is struct called ARMultiMarkerInfoT. In here,
what is the difference between var called "trans" and "transR"?
and what is "prevF"?

also the struct called ARMultiEachMarkerInfoT, In there,
what is the difference between "trans", "itrans" and "pos3d" ?
and what is "visible" and "visibleR"?

What is the relationship between ARMultiMarkerInfoT's trans and
ARMultiEachMarkerInfoT's trans?

When getting transformation from multiple markers, seems like we get a
global transformation from all of the markers, which is
ARMultiMarkerInfoT's trans. Is this correct?
If it is, is this global transformation located at the center of all
the markers?

Thanks for your time.
Sincerely,
Ronald
