[page:BufferGeometry] →
# [name]

This is the [page:BufferGeometry] port of [page:LatheGeometry].

## Code Example

```
const points = [];
for ( let i = 0; i < 10; i ++ ) {
points.push( new THREE.Vector2( Math.sin( i * 0.2 ) * 10 + 5, ( i - 5 ) * 2 ) );
}
const geometry = new THREE.LatheBufferGeometry( points );
const material = new THREE.MeshBasicMaterial( { color: 0xffff00 } );
const lathe = new THREE.Mesh( geometry, material );
scene.add( lathe );
```

## Constructor

### [name]([param:Array points], [param:Integer segments], [param:Float phiStart], [param:Float phiLength])

points — Array of Vector2s. The x-coordinate of each point must be greater than zero.

segments — the number of circumference segments to generate. Default is 12.

phiStart — the starting angle in radians. Default is 0.

phiLength — the radian (0 to 2PI) range of the lathed section 2PI is a closed lathe, less than 2PI is a portion. Default is 2PI.

This creates a LatheBufferGeometry based on the parameters.

## Properties

See the base [page:BufferGeometry] class for common properties.

### [property:Object parameters]

An object with a property for each of the constructor parameters. Any modification after instantiation does not change the geometry.

## Methods

See the base [page:BufferGeometry] class for common methods.
