    Sets the default orientation that should be used for viewing this model to REW. Setting a value equal to AxisAngle.ZERO indicates that no orientation is specified and so the viewer should use its default view.

  - getTaskManager
```
public TaskManager getTaskManager()
```
    Returns the task manager associated with this root model, if any.
    
    Returns:
    
    task manager, or null if there is none.
    
    See Also:

  - setTaskManager
```
public void setTaskManager(TaskManager tm)
```
    Experimental method that sets a task manager for this root model. This is a simulation control thread that will be started immediately after the model is loaded.
    This method will typically be called from the build(java.lang.String[]) method. Currently, task managers are not saved when a model is written to a file.
    
    Parameters:
    
    tm - task manager, or null to remove a task manager
    
    See Also:

  - prerender
```
public void prerender(RenderList list)
```
    Description copied from interface: IsRenderable
    
    Called prior to rendering to allow this object to update the internal state required for rendering (such as by caching rendering coordinates). The object may add internal objects to the list of objects being rendered, by calling
    list.addIfVisible (obj);
    for each of the objects in question.
    
    Specified by:
    
    prerender in interface IsRenderable
    
    Overrides:
    
    prerender in class RenderableModelBase
    
    Parameters:
    
    list - list of objects to be rendered
  - updateBounds
```
public void updateBounds(Vector3d pmin,
                         Vector3d pmax)
```
    Description copied from interface: IsRenderable
    
    Update the minimum and maximum points for this object. In an x-y-z coordinate system with x directed to the right and y directed upwards, the minimum and maximum points can be thought of as defining the left-lower-far and right-upper-near corners of a bounding cube. This method should only reduce the elements of the minimum point and increase the elements of the maximum point, since it may be used as part of an iteration to determine the bounding cube for several different objects.
    
    Specified by:
    
    updateBounds in interface IsRenderable
    
    Overrides:
    
    updateBounds in class RenderableModelBase
    
    Parameters:

  - rerender
```
public void rerender()
```
  - initialize
```
public void initialize(double t)
```
    Causes this model to initialize itself at time t. This method will be called at the very beginning of the simulation (with t = 0), or immediately after the model's state has been reset using HasState.setState(artisynth.core.modelbase.ComponentState), in which case t may have an arbitrary value.
    
    Specified by:

```
    Description copied from class: ComponentList
    
    Notifies this composite component that a change has occured within one or more of its descendants. When this occurs, the composite may need to invalidate cached information that depends on the descendants.
    This method should propagate the notification up the component hierarchy by calling notifyParentOfChange.
    
    Specified by:
    
    componentChanged in interface ComponentChangeListener
    
    Specified by:
    
    componentChanged in interface CompositeComponent

public void notifyStructureChanged(java.lang.Object comp)
```
  - hasState
```
public boolean hasState()
```
    Description copied from interface: ModelComponent
    
    Queries if this component has state. Structure change events involving components that have state will cause the current state history of of the system to be cleared.
    
    Specified by:
    
    hasState in interface ModelComponent
    
    Overrides:
    
    hasState in class ModelComponentBase
    
    Returns:
    
    true if this component has state
  - createState
```
public CompositeState createState(ComponentState prevState)
```
    Factory routine to create a state object for this component, which can then be used as an argument for HasState.setState(artisynth.core.modelbase.ComponentState) and HasState.getState(artisynth.core.modelbase.ComponentState). The state object does not have to be set to the component's current state. If the component does not have any state information, this method should return an instance of EmptyState.
    
    Specified by:
    
    createState in interface HasState
    
    Overrides:
    
    createState in class ModelBase
    
    Parameters:
    
    prevState - If non-null, supplies a previous state that was created by this component and which can be used to provide pre-sizing hints.
    
    Returns:
    
    new object for storing this component's state
  - setState
```
public void setState(ComponentState state)
```

    Specified by:

    Specified by:
    
    getState in interface HasState
    
    Overrides:
    
    getState in class ModelBase
    
    Parameters:
    
    state - receives the state information
  - getInitialState
```
public void getInitialState(ComponentState newstate,
                            ComponentState oldstate)
```
    Description copied from class: ModelBase
    
    Gets an initial state for this component and returns the value in state. If prevstate is non-null, then it is assumed to contain a previous initial state value returned by this method, and state should be set to be as consistent with this previous state as possible. For example, suppose that this component currently contains subcomponents A, B, and C, while the prevstate contains the state from a previous time when it had components B, C, and D. Then state should contain substate values for B and C that are taken from prevstate. To facilitate this, the information returned in state should contain additional information such as the identities of all the (current) subcomponents.
    
    Specified by:
    
    getInitialState in interface HasState
    
    Overrides:
    
    getInitialState in class ModelBase

    Parameters:
    
    annotated - specifies if the state should be annotated
    
    Returns:
    
    current state of the root model

```
    Description copied from class: ModelBase
    
    Advances this model from time t0 to time t1.

                  throws java.io.IOException

                     CompositeComponent ancestor)
              throws java.io.IOException
```
    Performs any required post-scanning for this component. This involves handling any information whose processing was deferred during the scan() method and stored in the token queue.

    working folder for this root model.
  - setWorkingFolder
```
public void setWorkingFolder(java.io.File dir)
