RadiationModel

public RadiationModel(Spectrum spectrumFactory,
              ObjectList<Spectrum> radiantPowerSum,
              ObjectList<Spectrum> absorbedPowerSum,
              ObjectList<Spectrum> reflectedPowerSum,
              ObjectList<Spectrum> transmittedPowerSum,
              ObjectList<Spectrum> sensedIrradianceSum,
              int[] idToGroup,
              ObjectList<ObjectList<RadiationModel.RayPoint>> rays,
              IntList hitCounterSum)

Create a new radiation model that adds collected radiation values to the lists.

Parameters:

spectrumFactory - factory to create spectra

radiantPowerSum - list to which absorbed radiant powers are added

absorbedPowerSum - list to which received radiant powers are added

reflectedPowerSum - list to which reflected radiant powers are added

transmittedPowerSum - list to which transmitted radiant powers are added

sensedIrradianceSum - list to which sensed irradiances are added

idToGroup - mapping from volume id to group index

rays - for debugging purposes, the traced rays will be added to the list. Use null if this is not needed

hit - counter list to which the number of hitting rays are added

Method Detail

compute

public abstract void compute(long rayCount,
           long seed,
           ProgressMonitor progress,
           int depth,
