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.


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

     SoType              SoPtSetGetClassTypeId()
          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.
