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.
Результат	void
