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

Look for: 二つの骨の角度を解く → 足先が段に届く。

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

例: 段差に置く足

  1. 1. Start

    足先が浮いている

  2. 2. Change

    二つの骨の角度を解く

  3. 3. Result

    足先が段に届く

地形に手足を合わせられる。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. 1. Input

    肩・肘・手先と目標

  2. 2. Process

    二関節の角度を解く

  3. 3. Result

    手先が目標に届く姿勢

A schematic of Two-Bone / Limb Inverse Kinematics. It shows the relationship between input, process, and result; exact values and rendering depend on the implementation.
