Believe it or not, making this function force-inline is actually a huge perf win.

Variables

NameDescription
bool bFullSphere

Full sphere?

bool bLineLight

True if this light has line-based falloff instead of point.

Geo::v128 BoundsMax

Axis aligned bounding box.

Geo::v128 BoundsMin

Axis aligned bounding box.

bool bSpotlight

Is this a spotlight?

Geo::v128 CosOuterCone_InvCosConeDiff_CosCullAngle_NegSinCullAngle

Pack four floats into a single v128 to avoid bloat.

Geo::v128 Direction

World space direction of the light.

Geo::u32 HasVisibility

Has visibility?

const float * IESProfileTable

IES profile table.

Geo::v128 Intensity_SqrRadius

RGB intensity of the light, plus square-radius packed into the w component.

Geo::v128 LightPos

World space position of light.

bool m_HasChanged

Whether the light has changed since it was last given to the extended direct lighting api.

const eLightType m_LightType

Type of input light corresponding to an eLightType enum value.

Geo::u64 m_Padding

Unused (this class is usually extended by one that starts with multiple v128s)

RadialFalloffModelType::CachedData RadialFalloffModel

Cached data for radial falloff model.

const Geo::u8 * VisibilityData

Visibility data.

Geo::s64 VisibilityDataU64

Visibility data.
