Logging tracking data to a xml file is broken, just empty lines for each logged frame. It was tested with the 2021.10 release.
Steps to reproduce:
- Open IGT Tracking Toolbox
- Select Virtual Tracker
- Add Single Tool
- Connect and start tracking
- Switch to Logging tab
- Choose "XML format"
- Click Start Logging
- Click Stop Logging
The file looks like this:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<Data ToolCount="2" version="1.0">
</Data>but should look like this:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<Data ToolCount="2" version="1.0">
