AtracsysModeSwitcherOp is the reusable visualization operator for the Atracsys visualizer app. It consumes replayed or live visible, infrared, structured-light, and marker-pose streams, then emits the currently selected base image, projected overlays, point clouds, and Holoviz text specs.

The operator keeps the Atracsys interaction model inside one reusable package:

  • keyboard-driven mode changes for interactive runs
  • placeholder outputs when a stream is not active yet
  • marker geometry projection onto visible or infrared frames
  • structured-light point rendering and tracking overlays
  • hardware-mode commands for the optional live camera source

Inputs:

  • in_visible_base
  • in_ir_base
  • in_structured_points
  • in_marker_poses

Outputs:

  • out_base
  • out_overlay
  • out_marker_points
  • out_points
  • out_mode_text
  • out_fiducial_text_coords
  • out_specs
  • out_hw_cmd

The application is responsible for providing a valid camera calibration and the marker geometry file.
