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
     }
