Our supplemental material consists of:

- supplemental.pdf: appendices to the main paper.

- renderings: actual renderings of the scenes used to compile Fig.~5 in
  the paper and Fig.~S3 in supplemental.pdf.

- sportscar/: EXR images of the sportscar scene. Reference images are in
  ref-*.exr.  The other files are named according to the sampler used, the
  environment map used for illumination, and then the number of pixel
  samples.

- sz-code/: part of the original code used in developing and testing the
  sequences.

- pbrt4/: pbrt-4 implementation of the Z-indexed SZ sampler.
  While fully functional, it is primarily meant for benchmarking using 64-bit
  integers and double precision real, not tested for 32-bit or GPU.
