[IGSTK-Users] optotrak igstkNDICertusTrackerTest GetTransform problem

[Yusuf OEZBEK]

Hi, Özgür

Sorry for late response.


I have the OPTOTRAK System values in file "optotrak.ini" ​​changed but unfortunately it has no effect for the error and I have no idea what it is and what will happen next.


I run the test following:

./igstkTests igstkNDICertusTrackerTest /home/yusuf/workspace/NDICertusTrackerTests/loggerOutput.txt /usr/NDIoapi/ndigital/rigid/smart_01.rig /usr/NDIoapi/ndigital/settings/optotrak.ini 


Actually my optotrak,.ini file look like this:


[TLD Info]
realtime =drealtim.tld
admin    =dadmin.tld
sensor   =dsensor.tld
oscope   =oscope2.tld

[OPTOTRAK System]

# Update the LinkDriver path according to your install.
# If using usb interface use usblink.so
# If using scsi interface use scsilink.so
# if using pci interface use pcilink.so

[SCSI]
ScsiPath 		= /dev/sg0
# If using scsilink update the ScsiPath according to your install.

[Ethernet Options]
Server Address=sscu-03040

# Server address is the IP address for the Optotrak
# System Control Unit. Edit the server address
# according to your network.

Control Port	= 9999
Data Port	= 10000
Data Timeout	= 10000
Reset Delay	= 10000


As I said with the same settings/configurations, the sample programs already works.


Thank you!


Mit freundlichen Grüßen
Yusuf ÖZBEK

Hi Yusuf, 
please use a lower frequency for tracking and let me know if this helped.
It seems your transformation, retrieved from the tracker, expires before it gets rendered.

Best,
Ozgur
