  - prerender
```
public void prerender(RenderList list)

    Description copied from interface: IsRenderable

    list.addIfVisible (obj);
    for each of the objects in question.
    
    Specified by:
    
    prerender in interface IsRenderable
    
    Overrides:

  - updateBounds
```
public void updateBounds(Vector3d pmin,

```
    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.

    Append to list the component (or components) associated with the qid-th selection query issued by this component's render method. This will only be called if this component manages its own selection (i.e., the number nums returned by IsSelectable.numSelectionQueriesNeeded() is positive), and qid will in turn be a number between 0 and nums-1.
    
    Specified by:
    
    getSelection in interface IsSelectable
    
    Overrides:
    
    getSelection in class RenderableComponentBase

```
public void setInverted(boolean inverted)

    Parameters:
    
    inverted - if true, marks this element as inverted.
  - isInverted
```
public boolean isInverted()
```
    Returns true if this element has been marked as inverted by the FEM code.
    
    Returns:

    Returns:
    
    true if one or more nodes are controllable
  - isDuplicatable
```
public boolean isDuplicatable()
```
    Returns true if this component can be duplicated. Duplication means that we can expect to be able to make a complete copy of the component along with all it's external references. This method should return true if and only if CopyableComponent.getCopyReferences(java.util.List<artisynth.core.modelbase.ModelComponent>, artisynth.core.modelbase.ModelComponent) returns true.
    This method is not currently used. It is intended to provide a faster way of determining if a component can be duplicated, without having to use CopyableComponent.getCopyReferences(java.util.List<artisynth.core.modelbase.ModelComponent>, artisynth.core.modelbase.ModelComponent) to build the list of copy references.
    
    Specified by:
    
    isDuplicatable in interface CopyableComponent
    
    Returns:
    
    true if this component can be duplicated.
  - getCopyReferences
```
public boolean getCopyReferences(java.util.List<ModelComponent> refs,
                                 ModelComponent ancestor)
```
    Collects external references which must also be copied in order to duplicate this component. These references should exclude those which are contained within a specified component hierarchy. This method should return true if and only if CopyableComponent.isDuplicatable() returns true.
    
    Specified by:
    
    getCopyReferences in interface CopyableComponent
    
    Parameters:
    
    refs - list to which references are appended
    
    ancestor - root node of the hierarchy from which references are to be excluded
    
    Returns:
    
    false if it is discovered that the component cannot be duplicated
  - getIndex
```
public int getIndex()
```
  - setIndex
```
public void setIndex(int idx)
```
  - getHardReferences
```
public void getHardReferences(java.util.List<ModelComponent> refs)
```
    Appends all hard references for this component to a list. References are other components, outside of this component's immediate ancestry, on which this component depends. For example, an AxialSpring refers to two Point components as for it's end points. A hard reference is one which the referring component must have, and which if deleted, implies that the referring component should be deleted too.
    
    Specified by:
    
    getHardReferences in interface ModelComponent
    
    Overrides:
    
    getHardReferences in class ModelComponentBase
    
    Parameters:

  - copy
```
public FemElement copy(int flags,
                       java.util.Map<ModelComponent,ModelComponent> copyMap)
```
    Description copied from interface: CopyableComponent
    
    Create a copy of this component. If COPY_REFERENCES is set in flags, then any component referenced by this component should itself be set to a copy. This should be done first checking copyMap for an existing copy of the referenced component. If there is no existing copy, then a copy should be created by calling copy recursively and adding the new copy to copyMap.
    
    Specified by:
    
    copy in interface CopyableComponent
    
    Overrides:
    
    copy in class RenderableComponentBase
    
    Parameters:
    
    flags - flags to control the copying
    
    copyMap - map to possible existing instances of referenced components

    computeCentroid in interface Boundable
    
    Parameters:
    
    centroid - returns the computed centroid value.
  - computeCovariance
```
public double computeCovariance(Matrix3d C)
```
    Description copied from interface: Boundable
    Computes the covariance of the element, assuming a uniform density of one. The covariance is defined as
```
 int_V \rho x x^T dV,
 
```
    where \rho is the density, x is any spatial point within the element, and the integral is evaluated over the element's spatial extent. The method returns the element's spatial size, which for elements of dimension 3, 2, 1, or 0 will be a volume, area, length, or discrete value.
    Implementation of this method is optional, with non-implementation indicated by having the method return -1. Non-implementation may prevent the element from being enclosed within certain types of oriented bounding box (OBB) constructions.
    Specified by:
    
    computeCovariance in interface Boundable
    
    Parameters:
    
    C - returns the covariance
    
    Returns:
    
    spatial size of the element, or -1 if this method is not implemented.
  - numPoints
```
public int numPoints()
```
    Description copied from interface: Boundable
    
    Returns the number of points associated with this element, if any, or zero otherwise. If the element has points, then it's spatial extent is assumed to be enclosed within their convex hull. At present, elements that do not have points cannot be enclosed within oriented bounding box (OBB) trees.
    
    Specified by:
    
    numPoints in interface Boundable

    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 HasNumericState
    
    Specified by:
    
    hasState in interface ModelComponent
    
    Overrides:
    
    hasState in class ModelComponentBase
    
    Returns:
    
    true if this component has state
  - notifyStateVersionChanged

public abstract void notifyStateVersionChanged()
```
  - getStateVersion
```
public int getStateVersion()
```
    Description copied from interface: HasNumericState
    
    Returns a version number for this component's state. When the version number changes, any previously saved state should be considered no longer compatible. The default implementation of this method always returns 0, indicating that state compatibility never changes.
    
    Specified by:
