As of Java 3D version 1.4.

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.

• Type of geometry array object (subclass of GeometryArray)
• vertexFormat
• texCoordSetCount
• texCoordSetMap
• validVertexCount
• validIndexCount, for IndexedGeometryArray objects
• stripVertexCounts array, for GeometryStripArray objects
• stripIndexCounts array, for IndexedGeometryStripArray objects

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(org.jogamp.java3d.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
