v0.4.0-beta

Open PGL 0.4.0

• Performance:

  • Optimized KNN lookup of guiding caches (x3 speed-up).
  • Optimized Cosine product for VMM based representations.

• Dependencies:

  • Removed the Embree library dependency for KNN lookups in favour
    of the header-only library nanoflann.

• Adding ARM Neon support (e.g., Apple M1).

• Fixing memory alignment bug for higher SIMD widths.

• PathSegmentStorage:

  • Fixing bug when multiple refracted/reflected events hit a
    distant source (i.e., environment map) by clamping to a max
    distance.
  • Adding GetMaxDistance and SetMaxDistance methods.
  • Adding GetNumSegments and GetNumSamples methods.

• Field:

  • Stopped tracing a total number of spp statistic since it is not really
    useful.
    • Removed the GetTotalSPP function.
    • Removed the numPerPixelSamples parameter from the Update function.
