ludus::graphics::rhi::RayCapabilities¶

Struct

Negotiated engine operations; unavailable fields are zero. Compute support alone does not establish ray support. Browser backends expose an unavailable profile.

Fields¶

StaticTriangles¶

bool ludus::graphics::rhi::RayCapabilities::StaticTriangles = false

Native immutable triangle BLAS/TLAS builds on an admitted hardware ray device.

Declared in modules/graphics/rhi/include/ludus/graphics/rhi/ray.h

InlineQueries¶

bool ludus::graphics::rhi::RayCapabilities::InlineQueries = false

Nearest accepted hit and early-exit accepted visibility with opacity filtering.

Declared in modules/graphics/rhi/include/ludus/graphics/rhi/ray.h

RayPipelines¶

bool ludus::graphics::rhi::RayCapabilities::RayPipelines = false

Native ray stage/function-table execution. Metal requires hardware traversal and function pointers.

Declared in modules/graphics/rhi/include/ludus/graphics/rhi/ray.h

ProceduralIntersections¶

bool ludus::graphics::rhi::RayCapabilities::ProceduralIntersections = false

Procedural intersections; false for RT0.

Declared in modules/graphics/rhi/include/ludus/graphics/rhi/ray.h

Updates¶

bool ludus::graphics::rhi::RayCapabilities::Updates = false

Native geometry updates/refits; false for RT0.

Declared in modules/graphics/rhi/include/ludus/graphics/rhi/ray.h

Motion¶

bool ludus::graphics::rhi::RayCapabilities::Motion = false

Motion geometry; false for RT0.

Declared in modules/graphics/rhi/include/ludus/graphics/rhi/ray.h

MaxInstances¶

ludus::foundation::uint32 ludus::graphics::rhi::RayCapabilities::MaxInstances = 0

Enabled maximum instances per scene, clamped from StorageLimits::RayInstances by backend/representation limits. Per-scene byte budgets may reject smaller scenes.

Related types: ludus::foundation::uint32

Declared in modules/graphics/rhi/include/ludus/graphics/rhi/ray.h

MaxRays¶

ludus::foundation::uint32 ludus::graphics::rhi::RayCapabilities::MaxRays = 0

Maximum rays per submitted batch; larger jobs must explicitly tile.

Related types: ludus::foundation::uint32

Declared in modules/graphics/rhi/include/ludus/graphics/rhi/ray.h

MaxBufferBytes¶

ludus::foundation::usize ludus::graphics::rhi::RayCapabilities::MaxBufferBytes = 0

Enabled native buffer/acceleration-structure/build-scratch range, further bounded by each admission budget. The packed opacity table has an independent 256 MiB representation bound: UV offsets count float4 words; scalar alpha offsets stay aligned to four values.
