# 参数化几何体（[name]）

生成由参数表示其表面的几何体。

## 示例

`var geometry = new THREE.ParametricGeometry( THREE.ParametricGeometries.klein, 25, 25 ); var material = new THREE.MeshBasicMaterial( { color: 0x00ff00 } ); var klein = new THREE.Mesh( geometry, material ); scene.add( klein );`

## 构造函数

### [name]([param:Function func], [param:Integer slices], [param:Integer stacks])

func — A function that takes in a [page:Float u] and [page:Float v] value each between 0 and 1 and modifies a third [page:Vector3] argument
slices — The count of slices to use for the parametric function
stacks — The count of stacks to use for the parametric function

## 属性

共有属性请参见其基类[page:Geometry]。

### [property:Object parameters]

一个包含着构造函数中每个参数的对象。在对象实例化之后，对该属性的任何修改都不会改变这个几何体。

## 方法(Methods)
