Beispiel

Skeleton.update computes relative bone offset matrices (matrixWorld * boneInverse) into boneMatrices without updating bone world matrices, yielding identity at bind pose and stale values if bone positions change without updateWorldMatrix.

Häufige Annahme

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

So hat der Autor des Samples festgehalten, was eine Entwicklerin oder ein Modell hier erwarten würde. Der Vertrag darunter ist das, was tatsächlich lief.

Contract

• 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.
