Method Detail

• numEmit

  int numEmit()

  Number of photons to emit from this surface.

  Returns:

  number of photons

• prepare

  void prepare(Options options,
               BoundingBox sceneBounds)

  Initialize this object for the specified scene size.

  Parameters:

  sceneBounds - scene bounding box

• store

  void store(ShadingState state,
             Vector3 dir,
             Color power,
             Color diffuse)

  Store the specified photon.

  Parameters:

  state - shading state

  dir - photon direction

  power - photon power

  diffuse - diffuse color at the hit point

• init

  void init()

  Initialize the map after all photons have been stored. This can be used to balance a kd-tree based photon map for example.

• allowDiffuseBounced

  boolean allowDiffuseBounced()

  Allow photons reflected diffusely?

  Returns:

  true if diffuse bounces should be traced

• allowReflectionBounced

  boolean allowReflectionBounced()

  Allow specularly reflected photons?

  Returns:

  true if specular reflection bounces should be traced

• allowRefractionBounced

  boolean allowRefractionBounced()

  Allow refracted photons?

  Returns:

  true if refracted bounces should be traced
