### SPHERE Files

The conventional suffix for `SPHERE` files is ``.sph'`.

    SPHERE
    Radius
    Xcenter Ycenter Zcenter

Sphere objects are drawn using rational Bezier patches, which are diced into meshes; their smoothness, and the time taken to draw them, depends on the setting of the dicing level, 10x10 by default. From Geomview, the Appearance panel, the `<N>ad` keyboard command, or a `dice nu nv` Appearance attribute sets this.
