DESCRIPTION
       This node is the	abstract base class for	all vertex-based shape (geome-
       try) nodes. It is used as a repository for  convenience	functions  for
       subclasses  and	to provide a type identifier to	make it	easy to	deter-
       mine whether a shape is vertex-based. It	contains one public field, the
       SoVertexProperty	field.

       All  subclasses of this node draw objects constructed from vertices. If
       the vertexProperty field	is non-null and	there are coordinates  in  the
       associated  vertex property node, then those coordinates	are used. Oth-
       erwise the objects are drawn  using  the	 current  coordinates  in  the
       state.  The  coordinates	 of  the  shape	are transformed	by the current
       transformation matrix and are drawn with	the current  light  model  and
       drawing style.

       Subclasses that construct polygons from vertices	may not	render or pick
       correctly if any	of their polygons are self-intersecting	or non-planar.

       All vertex shape	subclasses use the bounding box	of the shape to	deter-
       mine default texture coordinates. The longest dimension of the bounding
       box defines the S coordinates, and the next longest defines the T coor-
       dinates.	The value of the S coordinate ranges from 0 to 1, from one end
       of the bounding box to the other. The T coordinate ranges between 0 and
       the  ratio  of the second greatest dimension of the bounding box	to the
       greatest	dimension.

       When a vertex-based shape is picked with	an SoRayPickAction,  a	detail
       is  always returned. If the shape is composed of	faces (such as SoFace-
       Set or SoTriangleStripSet), an SoFaceDetail is returned.	 If the	 shape
       is  composed  of	 line segments (such as	SoLineSet), an SoLineDetail is
       returned. If the	shape is composed of points (such as  SoPointSet),  an
       SoPointDetail is	returned. Note that the	type of	detail returned	is not
       affected	by the current drawing style.

       Similarly, each class of	vertex-based shape invokes  appropriate	 call-
       backs  if  those	 callbacks  are	 registered with the SoCallbackAction.
       Shapes made of faces invoke triangle callbacks for each generated  tri-
       angle.	(Faces	may be triangulated to create these triangles.)	Shapes
       made of line segments invoke line segment callbacks for	each  segment,
       and shapes made of points invoke	point callbacks.

       The  subclass  SoIndexedShape  is  a base class for vertex-based	shapes
       that index into the current set of coordinates. The  subclass  SoNonIn-
       dexedShape is a base class for vertex-based shapes that use the current
       coordinates in order.
