post oprgb × lut → rgbimport fullseye as fs; fs.ledger.color_grade(rgb, lut) (実装を直接呼ぶなら import gfx2d; gfx2d.color_grade(rgb, lut)、台帳から引くなら opsgfx2d.get("color_grade"))Apply a 3-D colour LUT to an rgb image by trilinear interpolation.
lut is (n, n, n, 3) indexed [r, g, b] — the layout
:func:color_lut produces. The identity LUT returns the input to within
float64 rounding (measured maximum 3.3e-16), which is what makes this
testable without a reference implementation: trilinear interpolation of a
coordinate function is that coordinate, exactly.
