class newton.viewer.RecorderImGuiManager(renderer, recorder, example, window_pos=(10, 10), window_size=(300, 120))[source]#

Bases: ImGuiManager

An ImGui manager for controlling simulation playback with a recorder.

This class provides a graphical user interface for controlling simulation playback, including pausing, resuming, scrubbing through frames, and saving/loading recordings. It also manages the visualization of contact points and updates the renderer according to the selected frame.

__init__(renderer, recorder, example, window_pos=(10, 10), window_size=(300, 120))#

Initialize the RecorderImGuiManager.

Parameters:

  • renderer – The renderer instance used for visualization.

  • recorder – The recorder object that stores simulation history.

  • example – The simulation example object (must have .paused and .frame_dt attributes).

  • window_pos (tuple, optional) – The (x, y) position of the ImGui window. Defaults to (10, 10).

  • window_size (tuple, optional) – The (width, height) of the ImGui window. Defaults to (300, 120).

draw_ui()#

Draw the ImGui user interface for controlling playback and managing recordings.

This includes controls for pausing/resuming, frame navigation, saving, and loading.
