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 returnColor.BLACK
if they can't or don't wish to support this.- Specified by:
getGlobalRadiance
in interfaceGIEngine
- 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.
-
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 interfaceGIEngine
- Parameters:
state
- current render state describing the point to be computeddiffuseReflectance
- diffuse albedo of the point being shaded, this can be used for importance tracking- Returns:
- irradiance from indirect diffuse illumination at the specified point
