BHenyey–Greenstein Phase Function100%
観測方向で霧の明るさが変わる
Scrub to pause and inspect. At 0%, B matches A; at 100%, B shows the effect. The scene repeats every 8 seconds.
Look for: 散乱方向の重みを変える → 逆光で霧が強く光る。
This model simplifies the technique to show its use case and effect. Operation counts describe the model; they are not performance measurements.
