public class DepthComponentNative
extends DepthComponent

A 2D array of depth (Z) values stored in the most efficient format for a particular device. Values are not accessible by the user and may only be used to read the Z values and subsequently write them back.

DepthComponentNative

DepthComponentNative()

Package scope defualt constructor for use by cloneNodeComponent

DepthComponentNative

public DepthComponentNative(int width,
                    int height)

Constructs a new native depth (z-buffer) component object with the specified width and height.

Parameters:

width - the width of the array of depth values

height - the height of the array of depth values

Method Detail

getDepthData

void getDepthData(int[] depthData)

Copies the depth data from this object to the specified array.

Parameters:

depthData - array of ints that will receive a copy of the depth data

createRetained

void createRetained()

Creates a retained mode DepthComponentIntRetained object that this DepthComponentInt component object will point to.

Overrides:

createRetained in class NodeComponent

cloneNodeComponent

public NodeComponent cloneNodeComponent()

Creates a new DepthComponentNative object. Called from a Leaf node's duplicateNode method.

Overrides:

cloneNodeComponent in class NodeComponent

Returns:

a duplicate of the DepthComponentNative object.

See Also:

Node.duplicateNode(javax.media.j3d.Node, boolean), Node.cloneTree(), NodeComponent.setDuplicateOnCloneTree(boolean)

duplicateAttributes

void duplicateAttributes(NodeComponent originalNodeComponent,
                       boolean forceDuplicate)

Copies all node information from originalNodeComponent into the current node. This method is called from the duplicateNode method. This routine does the actual duplication of all "local data" (any data defined in this object).

Overrides:

duplicateAttributes in class NodeComponent

Parameters:

originalNodeComponent - 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.
