    public class Morph

extends Leaf

The Morph leaf node permits an application to morph between multiple GeometryArrays. The Morph node contains a single Appearance node, an array of GeometryArray objects, and an array of corresponding weights. The Morph node combines these GeometryArrays into an aggregate shape based on each GeometryArray's corresponding weight. Typically, Behavior nodes will modify the weights to achieve various morphing effects.

The following restrictions apply to each GeometryArray object in the specified array of GeometryArray objects:

- All N geometry arrays must be of the same type (that is, the same subclass of GeometryArray).

- The vertexFormat, texCoordSetCount, and validVertexCount must be the same for all N geometry arrays.

- The texCoordSetMap array must be identical (element-by-element) for all N geometry arrays.

- For IndexedGeometryArray objects, the validIndexCount must be the same for all N geometry arrays.

- For GeometryStripArray objects, the stripVertexCounts array must be identical (element-by-element) for all N geometry arrays.

- For IndexedGeometryStripArray objects, the stripIndexCounts array must be identical (element-by-element) for all N geometry arrays.

- For indexed geometry by-reference, the array lengths of each enabled vertex component (coord, color, normal, texcoord) must be the same for all N geometry arrays.

For IndexedGeometryArray objects, the vertex arrays are morphed before the indexes are applied. Only the indexes in the first geometry array (geometry[0]) are used when rendering the geometry.

### setWeights

    public void setWeights(double[] weights)

  Deprecated.
  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. The length of the `weights` parameter must be equal to the length of the array with which this Morph node was created, otherwise an IllegalArgumentException is thown.

  Parameters:

  Throws:
    `CapabilityNotSetException` - if appropriate capability is not set and this object is part of live or compiled scene graph

### cloneNode

    public Node cloneNode(boolean forceDuplicate)

  Deprecated.
  Creates a new instance of the node. This routine is called by `cloneTree` to duplicate the current node.

  Overrides:
    `cloneNode` in class `Node`
  Parameters:
    `forceDuplicate` - when set to `true`, causes the `duplicateOnCloneTree` flag to be ignored. When `false`, the value of each node's `duplicateOnCloneTree` variable determines whether NodeComponent data is duplicated or copied.
  See Also:
    `Node.cloneTree()`, `Node.cloneNode(boolean)`, `Node.duplicateNode(javax.media.j3d.Node, boolean)`, `NodeComponent.setDuplicateOnCloneTree(boolean)`

### duplicateNode

    public void duplicateNode(Node originalNode,
                              boolean forceDuplicate)

  Deprecated.
  Copies all node information from `originalNode` into the current node. This method is called from the `cloneNode` method which is, in turn, called by the `cloneTree` method.

  For any `NodeComponent` objects contained by the object being duplicated, each `NodeComponent` object's `duplicateOnCloneTree` value is used to determine whether the `NodeComponent` 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 `forceDuplicate` parameter in the `cloneTree` method to `true`.
  NOTE: Applications should not call this method directly. It should only be called by the cloneNode method.

  Overrides:
    `duplicateNode` in class `Node`
  Parameters:
    `originalNode` - the original node to duplicate.
    `forceDuplicate` - when set to `true`, causes the `duplicateOnCloneTree` flag to be ignored. When `false`, the value of each node's `duplicateOnCloneTree` variable determines whether NodeComponent data is duplicated or copied.
  Throws:
    `java.lang.ClassCastException` - if originalNode is not an instance of `Morph`
  See Also:
    `Node.cloneTree()`, `Node.cloneNode(boolean)`, `NodeComponent.setDuplicateOnCloneTree(boolean)`
