色々調整して気づいたんですがー
うーん
nearClipPlaneを動かすと ずれちゃいますね。
translate値に対して、nearClipPlane移動時のスケール比が考慮されてないのでずれちゃうわけですね。
なので、それを考慮した構造にしようかと思います。
構造修正
scaleSpaceで空間をスケールして、移動値に見た目上スケールが掛かってるようにします。
plateCtrlで移動を行い、 resolutionGateのサイズ合わせはここのスケールで行います。
これらをjointで作ることで、inverseScaleを発生させ 移動値のスケールとresolutionGateサイズの制御を切り離します。
それに伴い、出力カメラへのコネクションも修正しました。
スクリプトも修正
