# 函数曲线修改器

F-Curve modifiers are similar to object modifiers, in that they add non-destructive effects, that can be adjusted at any time, and layered to create more complex effects. Like object modifiers, F-curve modifiers are evaluated from the top down. In other words, the top modifier is calculated first and consequent modifiers are calculated in order. Modifiers can be moved by dragging the modifier box from the top right.

Modifiers can be muted or hidden by toggling the checkbox in the modifier's panel header. They can be removed using the delete button in the modifier's panel header.

## 修改器的类型

### 生成器修改器

Generator creates a polynomial function. These are basic mathematical formulas that represent lines, parabolas, and other more complex curves, depending on the values used.

Method used to represent the equation.

Equation in the form $$y = x^1 + x^2 + ... + x^n$$.

Equation in the form $$y = (Ax + B)(Cx + D)$$.

Change the Coefficient values to reshape the curve.

Controls the percentage of affect the modifier has on the F-curve.
