class Scene:
    """
    Represents a loaded scene in the simulation environment, holding workflow context and task execution state.

    Args:
        name (str): The name of the scene or task.
        pcd: Point cloud data associated with the scene.
        scale (float): Scale factor for the scene geometry.
        materials: Material data for the scene.
        textures: Texture data for the scene.
        floor_heights: Floor height information for the scene.
        wf: The task workflow instance managing this scene.
        task_id (int): The index of the current task within the workflow.
        task_exec_num (int): The execution count for the current task, used for task repetition tracking.
