slicing hierarchy - gingeradditive/OrcaSlicer GitHub Wiki
The Slicing logic is not the easiest to locate in the code base. Below is a flow diagram of function calls that are made after clicking the Slice Plate button in the UI. Most of the processing happens in different threads. Note the calls after BackgroundSlicingProcess::start(), but this is how you can find the slicing logic.
