fourdgsShMinBits top-level constant

int const fourdgsShMinBits

The narrowest and widest a spherical-harmonic band may declare (spec §6.5).

Eight is the coefficient as stored, so a band that declares it is exact; three leaves eight levels, which is the point at which a band stops describing a direction and starts describing a mood.

Implementation

const int fourdgsShMinBits = 3;
