# [name]

Class for generating meshes with axial symmetry. Possible uses include donuts, pipes, vases etc. The lathe rotate around the Z axis.

## Example

`var points = []; for ( var i = 0; i < 10; i ++ ) { points.push( new THREE.Vector3( Math.sin( i * 0.2 ) * 15 + 50, 0, ( i - 5 ) * 2 ) ); } var geometry = new THREE.LatheGeometry( points ); var material = new THREE.MeshBasicMaterial( { color: 0xffff00 } ); var lathe = new THREE.Mesh( geometry, material ); scene.add( lathe );`

## Constructor

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

points — Array of Vector3s. Since this rotates around Z axis, the y-values can be set to 0
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 2*PI) range of the lathed section 2*PI is a closed lathe, less than 2PI is a portion. Default is 2*PI
This creates a LatheGeometry based on the parameters.
