# 函数曲线修改器¶

## 添加修改器¶

F曲线修改器面板位于“属性”区域中。通过选择其中一个曲线点或通过选择通道列表来选择曲线。点击 添加修改器 菜单选择一个修改器。

## 修改器的类型¶

### 内建函数¶

• 正弦

• 余弦

• 切向

• 平方根

• 自然对数

• 标准正弦 (sin(x)/x)

### 封套¶

1:1 默认影响的参考值的上限距离。

### 循环¶

#### Trivially Cyclic Curves¶

When the Cycle Mode for both ends is set to either Repeat Motion or Repeat with Offset, and no other options of the modifier are changed from their defaults, it defines a simple infinite cycle.

This special case receives some additional support from other areas of Blender:

• Automatic Bézier handle placement is aware of the cycle and adjusts to achieve a smooth transition.

• The Cycle-Aware Keying option can be enabled to take the cycle into account when inserting new keyframes.
