    • update

      public boolean update(ParameterList pl, SunflowAPI api)
      Description copied from interface: RenderObject
      Update this object given a list of parameters. This method is guarenteed to be called at least once on every object, but it should correctly handle empty parameter lists. This means that the object should be in a valid state from the time it is constructed. This method should also return true or false depending on whether the update was succesfull or not.
      Specified by:
      update in interface RenderObject
      Parameters:
      pl - list of parameters to read from
      api - reference to the current scene
      Returns:
      true if the update is succesfull, false otherwise

    • getRadiance

      public Color getRadiance(ShadingState state)
      Description copied from interface: Shader
      Gets the radiance for a specified rendering state. When this method is called, you can assume that a hit has been registered in the state and that the hit surface information has been computed.
      Specified by:
      getRadiance in interface Shader
      Parameters:
      state - current render state
      Returns:
      color emitted or reflected by the shader

    • scatterPhoton

      public void scatterPhoton(ShadingState state, Color power)
      Description copied from interface: Shader
      Scatter a photon with the specied power. Incoming photon direction is specified by the ray attached to the current render state. This method can safely do nothing if photon scattering is not supported or relevant for the shader type.
      Specified by:
      scatterPhoton in interface Shader
      Parameters:
      state - current state
      power - power of the incoming photon.

    • isOpaque

      public boolean isOpaque()
      Description copied from interface: Shader
      Returns true if this shader is fully opaque. This gives a quick way to find out if a shader needs further processing when hit by a shadow ray.
      Specified by:
      isOpaque in interface Shader

    • getOpacity

      public Color getOpacity(ShadingState state)
      Description copied from interface: Shader
      Returns how much light is blocked by this shader.
      Specified by:
      getOpacity in interface Shader
