ConeGeometry constructor
      
      ConeGeometry([])
     
    
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 32
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.
