public Vector3f getCenter() {
        return center;
    }
Constructs a dome. Use this constructor for half-sphere, pyramids, or cones.
All geometry data buffers are updated automatically. <br>
For a cone, set planes=2. For a pyramid, set radialSamples=4 and planes=2.
Setting higher values for planes and radialSamples increases
the quality of the half-sphere.

@param center
           Center of the dome.
@param planes
           The number of planes along the Z-axis. Must be &gt;= 2.
           Influences how round the arch of the dome is.
@param radialSamples
           The number of samples along the radial.
           Influences how round the base of the dome is.
@param radius
           The radius of the dome.
@param insideView
           If true, the dome is only visible from the inside, like a SkyDome.
           If false, the dome is only visible from the outside.
