* Fix intrinsic LoadLocalRootTableConstant for optix (#7949)Harsh Aggarwal (NVIDIA)2025-08-07
| | | | | | | | | | | | Due to an older version of spec referred there was an inconsitency v1.29 2/20/2025 - [HitObject LoadLocalRootArgumentsConstant] Latest spec https://microsoft.github.io/DirectX-Specs/d3d/Raytracing.html#hitobject-loadlocalroottableconstant Refer: OptiX backend support for Shader Execution Reordering (SER) features as outlined in issue #6647. -
* cluster acceleration structure optix 6431 (#7028)Harsh Aggarwal (NVIDIA)2025-05-12
* Add cluster geometry intrinsics for ray tracing - Added GetClusterID() method to HitObject class - Added CandidateClusterID() and CommittedClusterID() methods to RayQuery class - Added SPV_NV_cluster_acceleration_structure extension support - Added GL_NV_cluster_acceleration_structure extension support - Added test files for RayQuery and HitObject cluster methods Fixes #6431 * OpRayQueryGetIntersectionClusterIdNV - unrecognized spirv Disabling spirv backend for SPV_NV_cluster_acceleration_structure hlsl.meta.slang(18674): error 29100: unrecognized spirv opcode: OpRayQueryGetIntersectionClusterIdNV result:$$int = OpRayQueryGetIntersectionClusterIdNV &this $iCandidateOrCommitted; ^~~~~~ hlsl.meta.slang(18670): error 30019: expected an expression of type 'int', got 'void' return spirv_asm ^~~~~~~~~ ninja: build stopped: subcommand failed. * 6431 - Fix spirv opcode * Remove tests * Add relevant tests * Review - Simplify tests
