Constructor Detail

Shape3D

public Shape3D()

Constructs a new Shape3D object with a null geometry component and a null appearance component.

Shape3D

public Shape3D(Geometry geometry)

Constructs a new Shape3D object with specified geometry component and a null appearance component.

Shape3D

public Shape3D(Geometry geometry,
               Appearance appearance)

Constructs a new Shape3D object with specified geometry and appearance components.

Method Detail

setModListener

public void setModListener(ScenegraphModificationsListener modListener)

Overrides:

setModListener in class Node

setVisible

public void setVisible(boolean visible)

Sets this Shape3D is visible or invisible.

isVisible

public final boolean isVisible()

Checks, whether this Shape3D is visible.

If the Appearance or the Appearance's RenderingAttributes is null or the RenderingAttributes are set to invisible false is returned.

setBounds

public final void setBounds(org.openmali.spatial.bounds.Bounds bounds)

Sets the bounds for this object.

Overrides:

setBounds in class Node

updateBoundsCheap

protected void updateBoundsCheap(boolean onlyDirty,
                                 boolean childrenToo,
                                 boolean parentToo,
                                 boolean onlyWorld)

Update bounds sets the bounds and virutal world bounds of all nodes recursively.

Overrides:

updateBoundsCheap in class Node

Parameters:

onlyDirty - Only update those nodes which have been marked as dirty.

childrenToo - if false, the children bounds are not updated

parentToo - if false, the parent Node will not be updated

onlyWorld - if true, only the vworld bounds are updated

updateBounds

public void updateBounds(boolean onlyDirty)

Update bounds sets the bounds and virutal world bounds of all nodes recursively.

Overrides:

updateBounds in class Node

Parameters:

onlyDirty - Only update those nodes which have been marked as dirty.

updateWorldTransform

public final void updateWorldTransform()

If this is a TransformGroupm then it will multiply the transform against the parent transform and store it into the world-transform matrix. Never use this method on your own! It's just for internal use.

Overrides:

updateWorldTransform in class Node

setLive

public final void setLive(boolean live)

Sets to live/not live. A shape is not live when it is no longer in the scenegraph.

Overrides:

setLive in class SceneGraphObject

setGeometry

public void setGeometry(Geometry geometry)

Sets the geometry for this object.

Parameters:

geometry - The new geometry

getGeometry

public Geometry getGeometry()

Returns:

the Geometry for this object.

setAppearance

public final void setAppearance(Appearance appearance)

Sets the appearance for this object.

getAppearance

public final Appearance getAppearance()

Returns:

the appearance for this object.

getAppearance

public Appearance getAppearance(boolean forceExistance)

Returns this shape's Appearance, if it exists. If it doesn't exist, it is created depending on the forceExistance parameter.

Parameters:

forceExistance - if true, a new Appearance is created and attached, if it doesn't already exist.

Returns:

the appearance for this object

newAppearance

public Appearance newAppearance()

Creates a new appearance for this Shape3D and returns it.

Returns:

A new appearance for this Shape3D

verifyAppChange

public final boolean verifyAppChange(OpenGLCapabilities glCaps)

setBumpMappingEnabled

public final void setBumpMappingEnabled(boolean enabled,
                                        Texture normalMapTex)

setBumpMappingEnabled

public final void setBumpMappingEnabled(boolean enabled,
                                        java.lang.String normalMapTex)

isBumpMappingEnabled

public final boolean isBumpMappingEnabled()

setIsShadowReceiver

public final void setIsShadowReceiver(boolean isSR)

isShadowReceiver

public final boolean isShadowReceiver()

sharedCopy

public Shape3D sharedCopy(CopyListener listener)

Creates a shared copy of this Node. A shared copy is one where the geometry and appearance is shared, but everything else is copied. This is a replacement for shared groups because of performance considerations. If you are loading the same model many times then this can save on memory and load times. The only allowable within the subtree are groups and shapes. This also copies a shapes bounds and turns autocomute off so that it is fast to insert the model into the scene.

Overrides:

sharedCopy in class Node

Returns:

a shared copy of this Node

See Also:

Node.absorbDetails(Node)

sharedCopy

public Shape3D sharedCopy()

Creates a shared copy of this Node. A shared copy is one where the geometry and appearance is shared, but everything else is copied. This is a replacement for shared groups because of performance considerations. If you are loading the same model many times then this can save on memory and load times. The only allowable within the subtree are groups and shapes. This also copies a shapes bounds and turns autocomute off so that it is fast to insert the model into the scene.

Overrides:

sharedCopy in class Node

Returns:

a shared copy of this Node

See Also:

Node.absorbDetails(Node)

absorbDetails

public void absorbDetails(Node node)

Turns the receiver into a shared copy of the node parameter. This is precisely the inverse operation of sharedCopy; i.e., shared copy creates a new node, but absorbDetails turns the current node into a copy exactly equivalent to what would be returned, if you created a new copy via the sharedCopy() method.

Overrides:

absorbDetails in class Node

Parameters:

node - the node to copy.

See Also:

Node.sharedCopy()

freeOpenGLResources

public void freeOpenGLResources(CanvasPeer canvasPeer)

This method frees OpenGL resources (names) for all Nodes in the traversal of this Node(-Group).

Specified by:

freeOpenGLResources in class Node

traverse

public boolean traverse(DetailedTraversalCallback callback)

Traverses the scenegraph from this node on. If this Node is a Group it will recusively run through each child.

Overrides:

traverse in class Leaf

Parameters:

callback - the listener is notified of any traversed Node on the way

Returns:

if false, the whole traversal will stop
