흔히 이렇게 알고 있다

Skeleton.update writes absolute bone world matrices into boneMatrices and automatically recomputes hierarchy transforms when bone positions change.

이 샘플의 작성자가 여기서 개발자나 모델이 기대할 법한 내용으로 적어둔 것이다. 아래 계약이 실제로 실행된 것이다.

컨트랙트

• Skeleton.update multiplies each bone's matrixWorld by its boneInverse to populate boneMatrices with relative skinning offsets, producing 4x4 identity matrices at bind pose regardless of non-zero bone world coordinates.
• Skeleton.update reads bone.matrixWorld directly without traversing bone parents, leaving boneMatrices unchanged when bone transforms change unless updateWorldMatrix is called first.
• Calling Skeleton.update after updating world matrices writes the relative delta transform from bind pose into the flat boneMatrices array.
• Skeleton.update sets boneTexture.needsUpdate to true and increments boneTexture.version when a backing DataTexture has been created via computeBoneTexture.
