Derived directional-albedo table
=================================

ggx_directional_albedo.npz includes a numerical transformation of the zinc
Fresnel LUT, which is derived from Werner CC0 zinc data and CIE CC BY-SA 4.0
datasets. The zinc-weighted arrays in this table are distributed under
CC BY-SA 4.0 with the attribution and share-alike obligations described in
../optics/LICENSE-derived.txt. The unit-Fresnel and Schlick arrays are
algorithmic data, included in the same archive for simplicity.

Generation method and archive hash are in manifest.json. Rebuild with
tools/galvanised/build_energy_tables.py; do not edit the archive by hand.
