This is the [page:BufferGeometry] port of [page:ConeGeometry].
const geometry = new THREE.ConeBufferGeometry( 5, 20, 32 );
		const material = new THREE.MeshBasicMaterial( {color: 0xffff00} );
		const cone = new THREE.Mesh( geometry, material );
		scene.add( cone );
		
		
		radius — Radius of the cone base. Default is 1.
		height — Height of the cone. Default is 1.
		radialSegments — Number of segmented faces around the circumference of the cone. Default is 8
		heightSegments — Number of rows of faces along the height of the cone. Default is 1.
		openEnded — A Boolean indicating whether the base of the cone is open or capped. Default is false, meaning capped.
		thetaStart — Start angle for first segment, default = 0 (three o'clock position).
		thetaLength — The central angle, often called theta, of the circular sector. The default is 2*Pi, which makes for a complete cone.
		
See the base [page:CylinderBufferGeometry] class for common properties.
An object with a property for each of the constructor parameters. Any modification after instantiation does not change the geometry.
See the base [page:CylinderBufferGeometry] class for common methods.
