InverseSimulationSettings – Setting an inverse simulation

Last update: 22.04.2026

The following script sample shows you an example on how to set an Inverse Simulation.

GetInverseSimulationSettings returns an InverseSimulationSettings object that allows you to modify geometry and simulation settings.

The InverseSimulationSettings object includes five main methods:

  • SetMonteCarlo with the parameters
    • bool dispersion
    • bool splitting
    • int nbGatheringRaysPerSource
    • int maxGatheringError
    • bool fastTransmissionGathering
    • int automaticSaveFrequencySeconds
    • EnumOptimizedPropagationMode
    • optimizedPropagation
    • int nbStandardPassesBeforeOptimizedPasses, optional
  • SetDeterminist with the parameters:
    • EnumPhotonMapMode
    • photonMapMode
    • int ambientSampling
    • int maxNbSurfaceInteractions
    • bool antiAliasing
    • int specularApproxAngle
  • SetDeterministPhotonMap with the parameters:
    • int maxNeighbors
    • int maxSearchRadius
    • bool fastTransmissionGathering
    • bool useFinalGathering
    • int finalGatheringMaxNeighbors, optional
    • int finalGatheringSplittingNb, optional
  • SetDeterministPhotonMapBuild with the parameters:
    • int nbPhotonsInDirectPhase
    • int nbSurfaceInteractionsInDirectPhase
  • SetPropagationErrorAnalysis(bool propagationErrorAnalysis)

SetInverseSimulationSettings applies the changes made with the GetInverseSimulationSettings function.

settings = inverseSimulation2.GetInverseSimulationSettings()
settings.SetDeterminist(SIM.InverseSimulationSettings.EnumPhotonMapMode.Load, 100, 10, False, 0)
settings.SetDeterministPhotonMapBuild(10000,100)
settings.SetDeterministPhotonMap(100, 10000000, True, False)
settings.SetPropagationErrorAnalysis(True)
inverseSimulation2.SetInverseSimulationSettings(settings)
