NDI Tracking Plugin

ImFusion Suite
1

Hi,

I am trying to connect the NDI Polaris Vega to ImFusion Suite. I added the NDI Tracking Stream from “Import”.

I am currently adding the NDI Polaris Vega’s Ip Address to the Hardware Device value. However, I am getting this message -

NDI_Tracking_Issue
NDI_Tracking_Issue1241×511 17.6 KB

I am able to track the pose of the Marker tool after generating the tool definition file (.rom) using NDI Track and NDI 6D Architect Version 3.

Would appreciate it if you could let me know why is this occurring?

Current System Configurations:

  1. Windows 10
  2. ImFusion Suite v2.41.1
  3. NDI Toolbox v5.004.015

Best,
Nalin

Hi Nalin,
I already replied privately to you by email but I add my response also here so that other people can find it.
The port parameter is currently not shown in the UI and can only be configured using a workspace file.
The following is an example workspace file where the port can be specified by replacing the string “INSERT_PORT_HERE” with the port number.

I tried replacing hardwarePort with COM7, which is the connection for our NDI tracker, but am wondering how to address hardwareDevice - we are using RS-232 communication (serial port) instead of IP. As of now, ImFusion cannot find our tracker. Do you have any advice on this? Thank you very much.

Edit: I was able to connect just by commenting out the hardwareDevice line and replacing ‘COM7’ with ‘7’. I still cannot see any transforms in the interface and, though I stream ‘Polaris Tracking Stream’ to an openIGT ‘Tracking Outstream’, cannot see any transforms upon reading the out stream either. Is there somewhere I can find these transforms? Thank you.
