public: const Geo::v128 & GetCoefficientBasisX() const


The basis vectors for the probe coefficients.

Must be axis aligned and orthonormal. Defaults to (+x, +y, +z).

public: const Geo::v128 & GetCoefficientBasisY() const

virtual const Geo::s8* Enlighten::IPrecompProbeSetBuildParameters::GetCoefficientOrder


public: const Geo::s8 * GetCoefficientOrder() const


The desired output order of the coefficients.

Must be called after SetNumSHCoefficients. The length of the array must be 4 for L1 probe sets, and 9 for L2. Each value maps the indexed coefficient to the position of the index in the coefficientOrder array. By default the order is {012345678} which maps to an output order of: Y_00, Y_11, Y_10, Y_1-1; Y_20, Y_21, Y_2-1, Y_2-2, Y_22

virtual float Enlighten::IPrecompProbeSetBuildParameters::GetDependencyIncludedSystemDistance


public: float GetDependencyIncludedSystemDistance() const


Bounding box of the probe set (i.e. bounding box containing all the probes) whose dependencies are being calculated is.

All systems whose bounding boxes intersect this expanded bounding box will be fully represented in ray tracing when calculating dependencies. Other systems will be represented as bounding boxes only.

public: float GetDependencyLocalityDistance() const


Maximum distance at which a given system will be considered local.
