<DL>
<DD>Sets this Morph node's morph weight vector. The Morph node "weights"
 the corresponding GeometryArray by the amount specified. 
 The weights apply a morph weight vector component that creates
 the desired morphing effect.

 of the array with which this Morph node was created, otherwise
 an IllegalArgumentException is thown.

<DL>
<DD>Copies all node information from <code>originalNode</code> into
 the current node.  This method is called from the
 <code>cloneNode</code> method which is, in turn, called by the
 <code>cloneTree</code> method.
 <P>
 For any <code>NodeComponent</code> objects
 contained by the object being duplicated, each <code>NodeComponent</code>
 object's <code>duplicateOnCloneTree</code> value is used to determine
 whether the <code>NodeComponent</code> should be duplicated in the new node
 or if just a reference to the current node should be placed in the
 new node.  This flag can be overridden by setting the
 <code>forceDuplicate</code> parameter in the <code>cloneTree</code>
 method to <code>true</code>.
 <br>
 NOTE: Applications should <i>not</i> call this method directly.
 It should only be called by the cloneNode method.
