Creates meshes with axial symmetry like vases. The lathe rotates around the Y axis.

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.LatheGeometry( points );

const material = new THREE.MeshBasicMaterial( { color: 0xffff00 } );

const lathe = new THREE.Mesh( geometry, material );

scene.add( lathe );

Constructor

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

points — Array of Vector2s. The x-coordinate of each point must be greater than zero. Default is an array with (0,-0.5), (0.5,0) and (0,0.5) which creates a simple diamond shape.

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 LatheGeometry based on the parameters.

Properties

.parameters : Object

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

WireframeGeometry

This can be used as a helper object to view a geometry as a wireframe.

Code Example

const geometry = new THREE.SphereGeometry( 100, 100, 100 );

const wireframe = new THREE.WireframeGeometry( geometry );

const line = new THREE.LineSegments( wireframe );

line.material.depthTest = false;

line.material.opacity = 0.25;

line.material.transparent = true;

scene.add( line );
