struct ludus::graphics::renderer::DirectLight final

Fields¶

ludus::foundation::uint64 ludus::graphics::renderer::DirectLight::SourceId = 0

Unique nonzero source identity within the submitted list; defines stable selection.

ludus::foundation::math::Vector3 ludus::graphics::renderer::DirectLight::Color {1, 1, 1}

Display-linear RGB hue, each channel in [0,1].

ludus::foundation::float32 ludus::graphics::renderer::DirectLight::Intensity = 1

Lux for directional, candela for point/spot, nits*m² for area samples; [0,1000000].
