Method Summary |
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(Scene scene)
Initialize the engine. |
boolean |

public PathTracingGIEngine(Options options)
requiresPhotons
public boolean requiresPhotons()
init
public boolean init(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
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 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
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
