    • Method Detail

      • getGlobalRadiance

        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). Engines can safely return Color.BLACK if they can't or don't wish to support this.
        Parameters:
        state - shading state
        Returns:
        color approximating global radiance
      • init

        boolean init​(Options options,
                     Scene scene)
        Initialize the engine. This is called before rendering begins.
        Returns:
        true if the init phase succeeded, false otherwise
      • getIrradiance

        Color getIrradiance​(ShadingState state,
                            Color diffuseReflectance)
        Return the incomming irradiance due to indirect diffuse illumination at the specified surface point.
        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
