DESCRIPTION

       This  node  represents  a  set  of  points  located  at  the  coordinates specified by the
       vertexProperty field (from  SoVertexShape)  or  the  current  inherited  coordinates.  For
       optimal performance, the vertexProperty field is recommended.

       SoPointSet  uses  the  coordinates  in  order,  starting with the first one. The number of
       points in the set is specified by the numPoints field.

       The coordinates of the point set are transformed by the current cumulative transformation.
       The points are drawn with the current light model and drawing style (drawing styles FILLED
       and LINES are treated as POINTS).

       Treatment of the current material and normal binding is as  follows:  PER_PART,  PER_FACE,
       and  PER_VERTEX  bindings  bind one material or normal to each point. The default material
       binding is OVERALL. The default normal binding is PER_VERTEX.

FIELDS

     SoSFInt32           numPoints
          Number of points.

METHODS

                         SoPointSet()
          Creates a point set node with default settings.

     static SoType       getClassTypeId()
          Returns type identifier for this class.

ACTION BEHAVIOR

       SoGLRenderAction
          Draws points based on the current coordinates, normals, materials, drawing  style,  and
          so on.

     SoRayPickAction
          Picks  points  based  on  the current coordinates and transformation. Details about the
          intersection are returned in an SoPointDetail.

     SoGetBoundingBoxAction
          Computes the bounding box that  encloses  all  points  in  the  set  with  the  current
          transformation  applied  to  them. Sets the center to the average of the coordinates of
          all points.

     SoCallbackAction
          If any point callbacks are registered with the action, they will be  invoked  for  each
          point in the set.

FILE FORMAT/DEFAULTS

          vertexProperty  NULL
