struct Enlighten::DirectionalLight::CachedData

    └>Enlighten::InputLightBase

Cached data for DirectionalLight.

Variables

Name Description
Geo::v128 m_Colour

RGB intensity of the light (linear space).

Geo::v128 m_Direction

World space position of light.

bool m_HasChanged

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

Geo::u32 m_HasVisibilityData

Has visisibility data?

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)

VisibilityBuffer m_VisibilityBuffer

Visibility buffer.
