NRD v3.7.0:

HIGHLIGHTS:

  • NRD: introduced NRD_NORMAL_ENCODING and NRD_ROUGHNESS_ENCODING parameters (controlled via CMake) to cover more encoding variants out of the box
  • NRD: introduced read-only "normalEncoding" and "roughnessEncoding" in "LibraryDesc" describing which encoding NRD has been compiled with
  • NRD: improved curvature estimation and usage for any type of supported normal encoding
  • NRD: fixed wrong curvature direction (was Y-flipped)
  • NRD: CLEAR_AND_RESTART now clears only "history" resources, including user-provided outputs
  • RELAX: fixed dynamic resolution scale related issue for specular (regression)
  • REBLUR: improved specular tracking
  • REBLUR: removed "enableAdvancedPrepass"
  • REBLUR: reduced potential chroma shifts
  • REBLUR_SH: fixed bias (increased lightness)
  • REBLUR_DIFFUSE_SPECULAR_SH: fixed wrong resource bindings if pre-pass is off
  • NRD INTEGRATION: descriptor caching is now based on native resource pointers instead of NRI pointers

DETAILS:

  • NRD: introduced NRD_NORMAL_ENCODING and NRD_ROUGHNESS_ENCODING
  • NRD: improved clears on CLEAR_AND_RESTART
  • NRD: removed shared NRD_NORMAL_ENCODING_ERROR
  • NRD: curvature error compensation made normal encoding dependent
  • NRD: fixed numerical instabilities in curvature estimation
  • NRD: fixed how thin lens equation interacts with concave surfaces
  • NRD: fixed wrong calculation of curvature direction
  • RELAX: NRD_NORMAL_ENCODING_ERROR => RELAX_NORMAL_ENCODING_ERROR (no functional changes)
  • RELAX: fixed resolution scale regression in virtual motion based reprojection for specular
  • RELAX: moving to using "ApplyThinLensEquation"
  • REBLUR: NORMAL_ULP increased from 0.0009 to 0.004 (1/255)
  • REBLUR: consistent REBLUR_NORMAL_ULP usage
  • REBLUR: removed / resolved some TODOs
  • REBLUR: prev-prev test improvements
  • REBLUR: changing luma doesn't allow energy boost
  • REBLUR: removed "enableAdvancedPrepass" (low IQ gains, adds bias in SH mode)
  • REBLUR_DIFFUSE_SPECULAR_SH: fixed wrong resource bindings if pre-pass is off
  • NRD INTEGRATION: descriptor caching is now based on native resource pointers instead of NRI pointers
  • NRD INTEGRATION: improved debug output
  • NRD INTEGRATION: NRI updated to v1.86
  • updated MathLib
