the update mentioned in my post from summer 2004 came out in Oct. 2004. there have been several other updates since. the PPT is now available as a version with 2 cams, one with 4 cams and one with 8 cams.
since March 2007, there is also a new system available called PPT-H which trackes with 175Hz and is even more stable with holding onto individual markers. this system can chain up to 32 cams and track up to 35 markers. the PPT is now reasonably good at following markers around, i.e. holding on to a marker's ID. however, to make sure markers are distinguished reliably, it is necessary to introduce some constraints (i.e. marker configurations). We usually use marker distance for this, as it is the most simple way of doing it.

Hi, mspusch
Our PPT is Version 2.17 with 4 cams, but I'm not sure how old it is. Do you think it support multiple markers well? Could you please post an example of how to set marker configurations? And I don't know what do you mean "use marker distance". Thanks for help.
