Fields¶

DirectLight ludus::graphics::renderer::ShadowRegion::Light {}

Exact light description. Point/area samples require all six canonical cube faces.

ludus::foundation::uint32 ludus::graphics::renderer::ShadowRegion::CubeFace = ~ludus::foundation::uint32{0}

Cube face 0..5 for point/area; all ones for directional/spot projections.

ludus::foundation::float32 ludus::graphics::renderer::ShadowRegion::NearDistance = .01F

Cube near distance in metres; canonical far distance is Light.Range.

ludus::foundation::math::Matrix4 ludus::graphics::renderer::ShadowRegion::WorldToClip = ludus::foundation::math::Matrix4::Identity()

Canonical conventional-depth light projection, Z [0,1], XY [-1,1], Y up.

rhi::RasterRectangle ludus::graphics::renderer::ShadowRegion::Interior {}

Inner drawing rectangle; must leave at least one texel of clear gutter on every side.

ludus::foundation::float32 ludus::graphics::renderer::ShadowRegion::Bias = 0.001F

Receiver bias in normalized light depth, [0,0.01], independent of camera reverse-Z.
