ludus::graphics::renderer::PlanarAreaLightDescription¶

Struct

One connected planar source patch; triangle tessellation does not change its area-weighted centroid or emitted power. Borrowed inputs are consumed synchronously.

Fields¶

PositionsMesh¶

ludus::foundation::BorrowedView<const ludus::foundation::math::Vector3> ludus::graphics::renderer::PlanarAreaLightDescription::PositionsMesh

Finite mesh-local positions; borrowed for this call.

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

Indices¶

ludus::foundation::BorrowedView<const ludus::foundation::uint32> ludus::graphics::renderer::PlanarAreaLightDescription::Indices

Triangle list with consistent outward winding; producer guarantees one connected patch.

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

MeshToWorld¶

ludus::foundation::math::Affine3 ludus::graphics::renderer::PlanarAreaLightDescription::MeshToWorld {}

Finite nonsingular transform; areas are computed in world metres.
