Scrub to pause and inspect. At 0%, B matches A; at 100%, B shows the effect. The scene repeats every 8 seconds.

Look for: 回転を混ぜて頂点を動かす → 関節の体積が保たれる。

This model simplifies the technique to show its use case and effect. Operation counts describe the model; they are not performance measurements.

例: ひねる腕

1. Start
骨がまっすぐ
2. Change
回転を混ぜて頂点を動かす
3. Result
関節の体積が保たれる

ねじれ時のつぶれを減らせる。時間変化を示す模式図です。実際の描画結果や処理速度を再現したものではありません。

How it works

1. Input
骨の回転と頂点
2. Process
双対四元数で変形を混合
3. Result
ねじれの体積を保つ

A schematic of Dual Quaternion Skinning / DQS. It shows the relationship between input, process, and result; exact values and rendering depend on the implementation.
