DESCRIPTION
     This node represents a sphere. By default, the sphere is centered at the
     origin and has a radius of 1. The sphere is transformed by the current
     cumulative transformation and is drawn with the current lighting model,
     drawing style, material, and geometric complexity.

     A sphere does not have faces or parts. Therefore, the sphere ignores
     material and normal bindings, using the first material for the entire
     sphere and using its own normals. When a texture is applied to a sphere,
     the texture covers the entire surface, wrapping counterclockwise from the
     back of the sphere. The texture has a seam at the back on the yz-plane.

FIELDS
     SoSFFloat           radius
          Radius of sphere. This must be greater than 0.


FUNCTIONS
     SoSphere *          SoSphereCreate()
          Creates a sphere node with default settings.

     SoType              SoSphereGetClassTypeId()
          Returns type identifier for this class.


ACTION BEHAVIOR
     SoGLRenderAction
          Draws sphere based on the current coordinates, materials, drawing
          style, and so on.

     SoRayPickAction
          Intersects the ray with the sphere. No details are created for
          intersections.

     SoGetBoundingBoxAction
          Computes the bounding box that encloses the sphere.

     SoCallbackAction
          If any triangle callbacks are registered with the action, they will
          be invoked for each successive triangle that approximates the
          sphere.

FILE FORMAT/DEFAULTS
     Sphere {
          radius  1
     }
