The cone is centered in its local coordinate system. For example, the upper surface of a cone whose top radius is
5 extends from
5 along the x- and z-axes.
If either the top or bottom radius is zero, the geometry forms a cone that tapers to an apex point at that end. If both top and bottom radii are nonzero, the geometry forms a frustum that tapers (or expands) from a circular base to a circular top. If both top and bottom radii are zero or less, or either if the top or bottom radius is less than zero, the geometry is empty. The default top radius is
You can animate changes to this property’s value. See Animating SceneKit Content.
