unilab.visualization¶

Visualization and playback helpers.

unilab.visualization.render_play_mode(env, *, sim_backend, initialize, step, num_steps, output_video=None, render_spacing=None, render_offset_mode=None, headless=None, record_video=None, frame_state_getter=None, camera_kwargs=None, extra_data_getter=None)[source]¶

Run playback through the env/backend playback contract.

sim_backend is retained for older call sites; backend selection now belongs to env.run_playback() and concrete backend implementations.

Parameters:

sim_backend (str)
initialize (Callable[[], TypeVar(ObsT)])
step (Callable[[TypeVar(ObsT)], TypeVar(ObsT)])
num_steps (int | None)
output_video (str | Path | None)
render_spacing (float | None)
render_offset_mode (str | None)
headless (bool | None)
record_video (bool | None)
frame_state_getter (Optional[Callable[[], ndarray]])
camera_kwargs (dict[str, Any] | None)
extra_data_getter (Optional[Callable[[], ndarray | None]])

Return type:

str | None
