ludus::graphics::renderer::BakedLighting¶

Struct

Metadata accompanying one baked irradiance chart; no runtime bake or chart packing.

Fields¶

Texture¶

rhi::TextureHandle ludus::graphics::renderer::BakedLighting::Texture {}

Ready single-mip linear RGBA8 chart with replicated gutters; null declares environment fallback.

Related types: rhi::TextureHandle

Declared in modules/graphics/renderer/include/ludus/graphics/renderer/lighting.hpp

Scale¶

ludus::foundation::math::Vector3 ludus::graphics::renderer::BakedLighting::Scale {1, 1, 1}

Linear irradiance multiplier in [0,10000]; texture stores normalized linear RGB.

Related types: ludus::foundation::math::Vector3

Declared in modules/graphics/renderer/include/ludus/graphics/renderer/lighting.hpp

UvTransform¶

ludus::foundation::math::Vector4 ludus::graphics::renderer::BakedLighting::UvTransform {1, 1, 0, 0}

Bake UV scale XY and offset ZW, selecting at least two interior texel centers per axis. Bounds must leave a replicated gutter texel plus half a texel on every side (1e-6 UV rounding tolerance).

Related types: ludus::foundation::math::Vector4

Declared in modules/graphics/renderer/include/ludus/graphics/renderer/lighting.hpp

AreTriangleChartsEnabled¶

bool ludus::graphics::renderer::BakedLighting::AreTriangleChartsEnabled = false

True selects independent guttered triangle charts from SceneFormat helpers, with power-of-two dimensions up to 4096, identity UvTransform and no mipmaps. False retains the legacy subrectangle transform admission. The producer must replicate each chart's gutter texels.

Declared in modules/graphics/renderer/include/ludus/graphics/renderer/lighting.hpp

HasStaticAreaDirect¶

bool ludus::graphics::renderer::BakedLighting::HasStaticAreaDirect = false

True declares static area direct diffuse in this chart; do not also submit raster area samples for its diffuse term. Analytic direct stays raster.

Declared in modules/graphics/renderer/include/ludus/graphics/renderer/lighting.hpp

SourceId¶

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

Exact nonzero source identity and authoring revisions required for bake validity.

Related types: ludus::foundation::uint64

Declared in modules/graphics/renderer/include/ludus/graphics/renderer/lighting.hpp

SceneRevision¶

ludus::foundation::uint64 ludus::graphics::renderer::BakedLighting::SceneRevision = 0

Scene bake revision; SceneItem must supply the same value.

Related types: ludus::foundation::uint64

Declared in modules/graphics/renderer/include/ludus/graphics/renderer/lighting.hpp

DependencyRevision¶

ludus::foundation::uint64 ludus::graphics::renderer::BakedLighting::DependencyRevision = 0

Cook dependency revision/hash; SceneItem must supply the same value.

Related types: ludus::foundation::uint64

Declared in modules/graphics/renderer/include/ludus/graphics/renderer/lighting.hpp

Transform¶

ludus::foundation::math::Affine3 ludus::graphics::renderer::BakedLighting::Transform {}

Exact local-to-world used by the bake; moved objects use environment fallback.

Related types: ludus::foundation::math::Affine3

Declared in modules/graphics/renderer/include/ludus/graphics/renderer/lighting.hpp

DirectLightId¶

ludus::foundation::uint64 ludus::graphics::renderer::BakedLighting::DirectLightId = 0

Optional baked direct-light identity; replace that light's diffuse term only for valid bakes. Zero replaces no analytic direct term; HasStaticAreaDirect separately declares area diffuse. One chart replaces at most one direct diffuse term; dynamic direct specular remains.
