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.
