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.

METHODS

                         SoSphere()
          Creates a sphere node with default settings.

     static SoType       getClassTypeId()
          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
     }
