_scatteringOrder int
Résultat ].double[

InitLobeData() public méthode

Initialize the lobe model parameters
public InitLobeData ( LOBE_TYPE _lobeType, float3 _incomingDirection, double _theta, double _roughness, double _scale, double _flatteningFactor, double _maskingImportance, double _oversizeFactor, bool _fitUsingCenterOfMass ) : void
_lobeType LOBE_TYPE Type of lobe to fit
_incomingDirection float3 Incoming light direction, pointing TOWARD the surface (Z-up)
_theta double Initial lobe theta angle
_roughness double Initial lobe roughness
_scale double Initial lobe scale
_flatteningFactor double Initial lobe flattening
_maskingImportance double
_oversizeFactor double Simulation oversize factor. A value of 1 makes the lobe fit exactly, a value higher than one will make the fit lobe smaller than the simulated data, a value lower than one will make the lob larger than the simulated data
_fitUsingCenterOfMass bool If true, the fitting distance is measured against a sphere centered on the Center of Mass rather than the (0,0,0) origin. Precision is usually better when using this option.
