Constructs a new cone geometry.

@param {number} [radius=1] - Radius of the cone base.
@param {number} [height=1] - Height of the cone.
@param {number} [radialSegments=32] - Number of segmented faces around the circumference of the cone.
@param {number} [heightSegments=1] - Number of rows of faces along the height of the cone.
@param {boolean} [openEnded=false] - Whether the base of the cone is open or capped.
@param {number} [thetaStart=0] - Start angle for first segment, in radians.
@param {number} [thetaLength=Math.PI*2] - The central angle, often called theta, of the circular sector, in radians.
The default value results in a complete cone.
