波長ごとの散乱差を空の色に反映できる
Scrub to pause and inspect. At 0%, B matches A; at 100%, B shows the effect. The scene repeats every 8 seconds.
Look for: 光路が長くなる → 夕景が赤く見える。
This model simplifies the technique to show its use case and effect. Operation counts describe the model; they are not performance measurements.
