v4.15.1-fixed

Same as v4.15.1, but resolved CMake's inability to shallow-clone a commit hash.

v4.15.1

HIGHLIGHTS:

• improvements and bug fixes

DETAILS:

• Slightly improved performance by compile-time specialization (see new CMake options, no breaking changes)
• Integration: banned ResourceSnapshot copying to immediately reveal invalid usage (the structure stores pointers to itself)
• GitHub actions: fixed always successful build
• REBLUR: dynamic enablePerformanceMode setting replaced with static REBLUR_PERFORMANCE_MODE macro and corresponding CMake option (low run-time value and high maintenance cost)
• CMake: updated ShaderMake and tagged the specific hash to prevent regressions
• CMake: added Arm64 support, including cross compilation
• NRI updated to v174
• increased scripts robustness

v4.15.0

v4.15.0:

HIGHLIGHTS:

• NRD: bug fixes and improvements
• NRD INTEGRATION: reworked, improved and simplified usage (added support for auto-wrapping of native objects)

DETAILS:

• NRD: samplers moved to a separate set (space) for sharing
• NRD: reworked DescriptorPoolDesc (and improved filling)
• NRD: reduced binding insanity
• NRD INTEGRATION: reworked and improved:
  • Destroy + Create simplified to Recreate (Destroy is still there)
  • added support for D3D11/D3D12/VK native objects (i.e. wrapping to NRI objects implemented "under the hood")
  • UserPool reworked to Texture (API specific) => Resource (texture + state) => ResourceSnapshot
  • added option autoWaitForIdle
  • fixed using a descriptor pool which has not finished execution yet (the issue appeared only once on the 2nd frame)
  • NRD sample extended to show ALL possible variants of using NRI based integration
• REBLUR/RELAX: improved specular tracking in general, but worsened on concave surfaces (see NRD_USE_SPECULAR_MOTION_V2)
• REBLUR: fixed rare light leaking caused by a greedy disocclusion threshold relaxation
• REBLUR: viewZ for the next frame must be copied with sky pixels
• REBLUR: misused curvatureAngle replaced with curvatureAngleTan
• REBLUR: fast history logic should use virtualHistoryAmount before fallback
• VK: reduced gaps between bindings to optimize memory usage of DescriptorSets
• VK: made useless UAV format validation happy
• CMake: added NRD_NRI option (OFF) to pull, build and include NRI into NRD SDK, required by NRD integration (Deploy script enables NRI for completeness)
• CMake: removed unnecessary SSE4.1 flag
• CMake: deleted NRD_DISABLE_SHADER_COMPILATION since it doesn't make any sence. NRD shaders get compiled by ShaderMake, which can be built for any (?) platform. In the nearest future tons of semi-manually crafter stub-shaders (entry points) will be replaced with permutations generated by ShaderMake
• Scripts: use all available cores for building
• Actions: significantly reduced task time
• improved docs
• added .clang-format

v4.14.3

HIGHLIGHTS:

• tagged a specific MathLib release

v4.14.2

HIGHLIGHTS:

• fixed compilation with GCC

DETAILS:

• updated MathLib

v4.14.1

HIGHLIGHTS:

• resolved issue #87
• bug fixes and improvements

DETAILS:

• REBLUR: fixed broken OCCLUSION denoisers if HitDistanceReconstructionMode != OFF
• REBLUR: DIRECTIONAL_OCCLUSION memory usage reduced by 5%

v4.14.0-fixed

HIGHLIGHTS:

• REBLUR: fixed wrong order of arguments breaking virtualHistoryAmount delivery to the Temporal Stabilization pass
• same as v4.14.0

v4.14.0

HIGHLIGHTS:

• REBLUR: improved performance (+6% in non-SH mode, +10% in SH mode)
• REBLUR: reduced memory usage (-10% in all modes)
• REBLUR: outputs are not used as history buffers anymore! (removed inter-frame dependencies)
• REBLUR: improved IQ by regaining more contact shadows
• RELAX/REBLUR: more flexible material ID support
• RELAX/REBLUR: improved specular motion calculation:
  • less dependent on curvature related hacks
  • better IQ on bumpy and wavy surfaces (common) in exchange of worsened IQ on concave mirrors (rare)
  • but there is a potential to get back specular motion acceleration on concave surfaces
  • old method is still available under NRD_USE_SPECULAR_MOTION_V2 macro switch (defined in Common.hlsli)

DETAILS:

• REBLUR: removed "hitDistance" related antilag settings (AO/SO is not temporally stabilized anymore)
• REBLUR: relaxed angular disocclusion checks if parallax is very small (~0 motion)
• REBLUR: temporal stabilization pass now operates only on luminance
• REBLUR: lots of C++ code changes to reflect changes in texture layouts
• REBLUR: fixed potential slightly lighter outline on border of material IDs
• RELAX/REBLUR: enableMaterialTestFor... replaced with minMaterialFor... to make material ID test more flexible
• RELAX/REBLUR: exposed hidden "gem" setting minHitDistanceWeight, which is handy for RESTIR/RTXDI-produced signals (default matches old behavior)
• RELAX: added missing "specMinHitDistanceWeight" adjustment by "smc"
• CMake: added support for CMAKE_MSVC_RUNTIME_LIBRARY coming from the parent project
• CMake: added INTERFACE target "NRDIntegration"
• updated ShaderMake
• cleanup

v4.12.0

HIGHLIGHTS:

• RELAX/REBLUR: returned back historyFixBasePixelStride to maximize flexibility (the default matches old behavior)
• CMake: various improvements

DETAILS:

• NRD: improved NRD_STATIC_LIBRARY support
• GIT: removed MathLib and ShaderMake submodules (conditionally downloaded via FetchContent)
• CMake: made Include folder PUBLIC for comfortable use in the parent project linking NRD
• CMake: adjustments
• CMake: added INTERFACE target NRDIntegration
• RELAX/REBLUR: returned back historyFixBasePixelStride
• REBLUR: slightly boosted performance in the performance mode
• RELAX: minor code cleanup
• updated docs

v4.11.4 (fixed)

REBLUR/RELAX: fixed a critical regression breaking the Pre-pass logic
