DILIGENT_TLAS_INSTANCE_DATA_SIZE

#define DILIGENT_TLAS_INSTANCE_DATA_SIZE   64

Top-level AS instance size in bytes in GPU side. Used to calculate size of BuildTLASAttribs::pInstanceBuffer.

DILIGENT_TLAS_INSTANCE_OFFSET_AUTO

#define DILIGENT_TLAS_INSTANCE_OFFSET_AUTO   0xFFFFFFFFU

Can be used to calculate the TLASBuildInstanceData::ContributionToHitGroupIndex depending on instance count, geometry count in each instance (in TLASBuildInstanceData::pBLAS) and shader binding mode in BuildTLASAttribs::BindingMode.

Example: InstanceOffset = BaseContributionToHitGroupIndex; For each instance in TLAS if (Instance.ContributionToHitGroupIndex == TLAS_INSTANCE_OFFSET_AUTO) Instance.ContributionToHitGroupIndex = InstanceOffset; if (BindingMode == HIT_GROUP_BINDING_MODE_PER_GEOMETRY) InstanceOffset += Instance.pBLAS->GeometryCount() * HitGroupStride; if (BindingMode == HIT_GROUP_BINDING_MODE_PER_INSTANCE) InstanceOffset += HitGroupStride;
