In my previous meesage, please replace
arGetTransMatCont(&marker_info[k], previous_trans, object[i].center,
previous_trans = object[i].trans;
arGetTransMatCont(&marker_info[k], object[i].trans, object[i].center,
I had tested code (2) at first and was wondering whether the function was
using the previous transformation at all. Therefore, I tried to store the
previous information as shown in (1). As this led to unstable tracking
results, it seems that it is OK to call arGetTransMatCont as shown in (2).
Indeed, object[i].trans is first read and then it is written. Therefore, the
first object[i].trans is the one that has been written in the previous
Hope you solved your problem there...
PS: Has anyone tried to make a comprehensive C++ port of the ARToolKit,
using a GUI other than Glut? What about JARToolKit? I am also looking for
documentation in general, FAQs, old messages etc. Any information using
stereo cameras to track patterns would be also greatly appreciated!

Objet : Stable tracking with ARToolkit
I'm looking for some help concerning the
stability of the tracking of ARToolKit.
If a human being holds the pattern in his hand
you have some kind of shivering effect since
ATK processes (of course) every smallest
I heard that there are some references
to source code solving this problem.
Can someone provide me with these references
or even with code solving this problem?
Any help is appreciated!
