# 麻辣土豆模型和动作提取：四、摄像机

* “土豆”指的是偶像大师百万现场剧场时光（ミリシタ/MLTD）

10月更新：近日在测试玩具的时候，发现 Unity 是直接支持 F-Curve 的（见 KeyFrame 的文档），而且其构造函数已经清楚地说明了值的意义。是我孤陋寡闻了。

Although F-Curves are very similar to Bézier Curves, there are some important differences.

For obvious reasons, a property represented by a Curve cannot have more than one value at a given time, hence:

• When you move a control point ahead of a control point that was previously ahead of the point that you are moving, the two control points switch their order in the edited curve, to avoid that the curve goes back in time.
• For the above reason, it is impossible to have a closed F-Curve.
