```
public static SbMatrix getMatrix(SoState state,
                                 int index)
```
    Returns the matrix transform (WC to VRC) for the light i for an SoCallbackAction. Returns the modelling matrix for other action.
  - getLights
```
public static java.util.Vector<SoNode> getLights(SoState state)
```
    Returns the current list of light nodes from the state.
