Modifier and Type	Method and Description
`Color`	`getGlobalRadiance(ShadingState state)` This is an optional method for engines that contain a secondary illumination engine which can return an approximation of the global radiance in the scene (like a photon map).
`Color`	`getIrradiance(ShadingState state, Color diffuseReflectance)` Return the incomming irradiance due to indirect diffuse illumination at the specified surface point.
`boolean`	`init(Options options, Scene scene)` Initialize the engine.

  - getIrradiance
```
public Color getIrradiance(ShadingState state,
                           Color diffuseReflectance)
```
    Description copied from interface: GIEngine
    
    Return the incomming irradiance due to indirect diffuse illumination at the specified surface point.
    
    Specified by:
    
    getIrradiance in interface GIEngine
    
    Parameters:
    
    state - current render state describing the point to be computed
    
    diffuseReflectance - diffuse albedo of the point being shaded, this can be used for importance tracking
    
    Returns:
    
    irradiance from indirect diffuse illumination at the specified point
  - getGlobalRadiance
```
public Color getGlobalRadiance(ShadingState state)
```
    Description copied from interface: GIEngine
    
    This is an optional method for engines that contain a secondary illumination engine which can return an approximation of the global radiance in the scene (like a photon map). Engines can safely return Color.BLACK if they can't or don't wish to support this.
    
    Specified by:
    
    getGlobalRadiance in interface GIEngine
    
    Parameters:
    
    state - shading state
    
    Returns:
    
    color approximating global radiance
  - init
```
public boolean init(Options options,
                    Scene scene)
```
    Description copied from interface: GIEngine
    
    Initialize the engine. This is called before rendering begins.
    
    Specified by:
    
    init in interface GIEngine
    
    Returns:
    
    true if the init phase succeeded, false otherwise
