QT Visualizer

I played around with a simple 2D lidar and wanted to make sense of what lidar generates. What I ended up doing is to create a standlone QT server which listens on UDP with proto text formating.

That is launching ./qt_visualizer binary which blocks and waits for the incoming UDP packets and then in another terminal launching ./smoke_test_main which feeds these protos in text format:

items {
  theta: 45414
  distance_mm: 2294
  quality: 60
}
items {
  theta: 46620
  distance_mm: 4797
  quality: 60
}

which shows data in the PolarChartView

Why not combining plot with getting data from lidar?

Initially I was going to do just that. If you want to use some sort of QT, then QT will usurp the whole project. There will be a main QT application with their own data models, macros, events, two compilers and a lot more. My main project was in Bazel. It is possible to use QT in Bazel, but it would be a lot simpler with CMake especially that I can use Absceil, protos, glog and other libraries that I need.
