[IGSTK-Users] IGSTK: Polaris and recorded images synchronization

[l khinwee]

HI Patrick,

I have seen the link you given before. It is the software developed namely 
SynchroGrab4D, in the last few weeks, i have also contacted with David Gobbi, 
who are one of the author/developer for this software. The reason why i give up 
to implement this SynchroGrab4D, is because they are not using any video 
grabber/frame grabber, they using Ultrasonix (PC based ultrasound machine) so 
that they can have direct access of the computer memory to get the recording 
images. All the coding in this software are mixed with Ultrasonix coding. So, if 
i am not using this ultrasound machine, i cannot build the application 
successfully. I have tried to comment out the related coding from Ultrasonix, 
but it seems like far more complicated as i thought.
However, this is the only example coding/software that are available online and 
related to vtkNDITracker, i could not find any more others examples, as more 
people working on tracking devices with IGSTK only, rather than VTK.
Please correct me, if i am mistake.

Lai

Hi Lai,

You might find this reference helpful:

vtkNDITracker class is the precursor of igstk tracker code. If that 
tracking code works and you have your video recording working in VTK, I 
would recommend you do it in VTK.

VideoGrabber component is currently under development, so there is no 
video recording capability in IGSTK yet. Once we have that, it will be 
relatively easy to do this in IGSTK.

I hope this helps,

Patrick
