動く点群から面を再構成できる
Scrub to pause and inspect. At 0%, B matches A; at 100%, B shows the effect. The scene repeats every 8 seconds.
Look for: 点の移動後に分割を更新 → 面のつながりが変わる。
This model simplifies the technique to show its use case and effect. Operation counts describe the model; they are not performance measurements.
