[IGSTK-Users] Dome volume in NDI Aurora

[Andrew Wiles]

Hello Matt,

If you want to make use of the dome volume you must explicitly select it using the VSEL command in the API.  The last time I used IGSTK, which was several years ago, I was not able to use the dome volume because the VSEL command was not included in the initialization section.  There is a flow chart in our API guide that explains how this works.

Regards,
Andrew

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

Hi there,

what I mean is that it appears that I can only track within a cube volume. Im not trying to visualise it at this stage. So, if I look here:
http://www.ndigital.com/medical/products/aurora/#specifications-planer-field

the tracking range appears to match the cube. I would like to be able to track a larger field of view, as specified by the dome volume.

Is that possible?

Thanks

Matt

Hello Matt,
What do you mean by "defaults" to the cube volume?
Are you referring to the working volume (EM field) representation?
Do you want to have a representation of the tracking/working volume of the aurora in your scene?
I cannot load the file auroraEMField.msh right now. Have you opened it? Is that a representation of a cube or a dome?
If it is out-of-date (not a dome) we should ask NDI for a new STL or build a new one from the specifications.

let me know if I have understood correctly your problem
best regards,
sebastian
