Detailed Description

Device-level shared BLAS residency. Owns no scene objects or TLAS instance registry.

CPU containers are allocated during core-system startup and released during core-system shutdown. Backend resources are created only after the GAL device exists and are released during high-level shutdown. Callers never construct or own a manager object.

AddBuildPass()

xiiRayTracingResources::BuildHandles xiiRayTracingResources::AddBuildPass ( xiiRenderGraph & graph, xiiUInt64 uiFrameIndex, xiiRayTracingFrameResources & worldResources, const xiiGpuInstanceData & instances, const xiiArrayPtr< const xiiUInt32 > * selection = nullptr, xiiRayTracingFrameResources * sharedGeometry = nullptr )

staticnodiscard

Adds BLAS/TLAS construction to the graph on the compute queue.

A frame-in-flight TLAS ring prevents updates from mutating acceleration structures still used by older GPU submissions. The returned dependency buffer must be declared as a BuildASRead by every trace pass that consumes the returned TLAS. sharedGeometry optionally reuses the same world's deformation and dynamic BLAS across occurrences without sharing their writable TLAS or hit-data allocations.
