It looks to me like the Aurora defaults to the Cube volume. Is there a way to switch to the Dome volume? Thanks Matt -------------- next part -------------- An HTML attachment was scrubbed...

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 If it is out-of-date (not a dome) we should ask NDI for a new STL or build a new one from the specifications.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 -------------- next part -------------- An HTML attachment was scrubbed...

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?

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 On 3/13/2015 7:24 AM, Clarkson, Matt wrote: > Hi there, > > what I mean is that it appears that I can only track within a cube > volume.

Always run in release mode, debug mode slows everything down and introduces a lot of timing issues. 2. If you are on windows then please stop/disable as many services as you can. These are automatically running in the background and our experience has been that they degrade the tracking rate performance. We tested this a couple years ago and our results showed a bimodal distribution of the refresh rate around the rate we set (we did not encounter this on linux - was unimodal with mean/median at approximately the refresh rate we set). hope this helps Ziv -- Ziv Yaniv, PhD, Senior Scientist, Office of High Performance Computing and Communications National Library of Medicine National Institutes of Health Bldg. 38A, Room B1N30D 8600 Rockville Pike, Bethesda, MD, 20894 Phone:+1-301-435-6633 Email: zivyaniv at nih.gov From: Dominique Maier > Date: Friday, March 13, 2015 at 11:32 AM To: "igstk-users at public.kitware.com" > Subject: [IGSTK-Users] NDI Polaris Spectra - max refresh rate Hello!
