Method Detail

• prepare

  public void prepare​(Options options,
                      BoundingBox sceneBounds)

  Description copied from interface: PhotonStore
  Initialize this object for the specified scene size.

  Specified by:

  prepare in interface PhotonStore

  sceneBounds - scene bounding box

• size

  public int size()

• store

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

  Description copied from interface: PhotonStore
  Store the specified photon.

  Specified by:

  store in interface PhotonStore

  Parameters:

  state - shading state

  dir - photon direction

  power - photon power

  diffuse - diffuse color at the hit point

• init

  public void init()

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

  Specified by:

  init in interface PhotonStore

• precomputeRadiance

  public void precomputeRadiance​(boolean includeDirect,
                                 boolean includeCaustics)

• getRadiance

  public Color getRadiance​(Point3 p,
                           Vector3 n)

  Description copied from interface: GlobalPhotonMapInterface
  Lookup the global diffuse radiance at the specified surface point.

  Specified by:

  getRadiance in interface GlobalPhotonMapInterface

  Parameters:

  p - surface position

  n - surface normal

  Returns:

  an approximation of global diffuse radiance at this point

  public int numEmit()

  Description copied from interface: PhotonStore
  Number of photons to emit from this surface.

  Specified by:

  numEmit in interface PhotonStore

  Returns:

  number of photons
