A class for generating cone geometries.

Code Example

const geometry = new THREE.ConeGeometry( 5, 20, 32 ); const material = new THREE.MeshBasicMaterial( {color: 0xffff00} ); const cone = new THREE.Mesh( geometry, material ); scene.add( cone );


[name]([param:Float radius], [param:Float height], [param:Integer radialSegments], [param:Integer heightSegments], [param:Boolean openEnded], [param:Float thetaStart], [param:Float thetaLength])

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:CylinderGeometry] 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.


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