[IGSTK-Users] Dome volume in NDI Aurora

[Sebastian Ordas]

Hi,
To my knowledge, IGSTK does not restrict the working volume of the 
tracker: when the sensor exits the working volume, no transformation is 
updated, the valid time for the representation of the tracked object 
(e.g. needle tip) expires and it is no longer rendered.

NDI guys have a couple of IGSTK apps for in-house use. Maybe they can 
test it.

I did only test myself the old aurora EM field generator a while ago. I 
will check if I am missing any Aurora configuration parameter.

best regards,
sebastian
