While 3D Slicer - using SlicerIGT/Plus - have been supporting real-time position tracking using high-end devices (optical trackers, electromagnetic trackers, surgical navigation system, etc), there has been no ultra-low-cost tracking solution available - until now. With latest version of Plus toolk…

Can you please upload the Slicer scene somewhere so that it can be easily tried without having to create each object with CreateModels? It would make it much easier for others to start. Thanks!

Good idea. An example 3D Slicer scene file is available here . It displays markers that are in this marker sheet (pdf file, ready for printing) . You may need to zoom in-out 3D views after you place the markers in the field of view of your camera to make the markers show up.

I am having a problem with the device set configuration file in Plus Server Launcher. After choosing the device set “PlusServer: Optical marker tracker using MMF video”, I have followed the example presented here http://perk-software.cs.queensu.ca/plus/doc/nightly/user/DeviceOpticalMarkerTracker.htm…

It seems that you need help with getting Plus set up right. To get help on this, please submit an issue on Github page of Plus .

I’ve updated the links now (Plus repositories moved since the time of the original post).

I´m trying to make from scratch my own 3d Slicer scene and I´ve problems creating vector volume image_image. I´m following SlicerIGT tutorials but i can´t find solution. Thanks!

Normally you would just let OpenIGTLinkIF module create image and transform nodes for you, but you can certainly create them from your own Python script, too. Here is an example of creating a scalar volume node: https://www.slicer.org/wiki/Documentation/Nightly/ScriptRepository#Create_a_new_volume . …

Thanks Andras, really usefull info.

Little more complex. How can I add a second video source to the scene? I have 2 Plus connections with different ports for each device (18944/18945 and 18954/18955). Both successfully connected. I´ve added in OpenIGTLinkIF 2 connectors for the second camera and config properly ports but … i have no …
