Rig IK FK Control Chain Guide

Inverse Kinematics - Inverse Kinematics becomes useful only when the reviewer can point to the part of control rig, deformation proof, IK/FK switch, driven key, or animation-ready setup that it changes. Inverse Kinematics (反向动力学 / インバースキネマティクス) should be reviewed through control behavior and curve shape. Keep the pose test, curve screenshot, IK/FK state, and contact-frame proof so animation approval is not based on playback alone. If that proof cannot be attached, the term should remain in review rather than be treated as covered.

Forward Kinematics - For a vendor-facing brief, Forward Kinematics is the anchor term and the localized labels explain the same inspected state. Forward Kinematics (正向动力学 / フォワードキネマティクス) should be reviewed through control behavior and curve shape. Keep the pose test, curve screenshot, IK/FK state, and contact-frame proof so animation approval is not based on playback alone. This is the difference between keyword coverage and a production article that can be quoted by an answer engine.

Keyframe - The practical question around Keyframe is what evidence would make another reviewer agree with the same decision. Keyframe (关键帧 / キーフレーム) should be reviewed through control behavior and curve shape. Keep the pose test, curve screenshot, IK/FK state, and contact-frame proof so animation approval is not based on playback alone. The translation is therefore tied to evidence, not to an isolated glossary row.

Curve Editor - Treat Curve Editor as a production checkpoint: it should narrow the review, not decorate the page with another synonym. Curve Editor (曲线编辑器 / カーブエディタ) should be reviewed through control behavior and curve shape. Keep the pose test, curve screenshot, IK/FK state, and contact-frame proof so animation approval is not based on playback alone. That keeps the article searchable while still giving rigger or character technical artist something concrete to approve.

Ease In / Ease Out - Ease In / Ease Out should be read through 动画, not as a loose label in a translation sheet. Ease In / Ease Out (缓入缓出 / イーズイン/イーズアウト) should be reviewed through control behavior and curve shape. Keep the pose test, curve screenshot, IK/FK state, and contact-frame proof so animation approval is not based on playback alone. Use the note to decide whether the asset is ready, blocked, or waiting for a narrower specialist pass.

Bone Chain - When 骨骼链 or ボーンチェーン appears in a review note, the English term still needs the file state beside it. Bone Chain (骨骼链 / ボーンチェーン) needs motion proof, not only a neutral pose. Test an expected range, an extreme pose, and a reset state so animators know whether the rig behavior is stable. If that proof cannot be attached, the term should remain in review rather than be treated as covered.

End Effector - End Effector becomes useful only when the reviewer can point to the part of control rig, deformation proof, IK/FK switch, driven key, or animation-ready setup that it changes. End Effector (末端效应器 / エンドエフェクタ) needs motion proof, not only a neutral pose. Test an expected range, an extreme pose, and a reset state so animators know whether the rig behavior is stable. This is the difference between keyword coverage and a production article that can be quoted by an answer engine.

Pole Vector - For a vendor-facing brief, Pole Vector is the anchor term and the localized labels explain the same inspected state. Pole Vector (极向量 / ポールベクター) needs motion proof, not only a neutral pose. Test an expected range, an extreme pose, and a reset state so animators know whether the rig behavior is stable. The translation is therefore tied to evidence, not to an isolated glossary row.
