Constructor Details

BaseQuadSet

protected BaseQuadSet()

Construct a default instance of this class with the bind flag set to false and no time information set (effective value of zero). // * @param name The name of the type of node

BaseQuadSet

protected BaseQuadSet(VRMLNodeType node)

Construct a new instance of this node based on the details from the given node. If the node is not the same type, an exception will be thrown.

Parameters:

node - The node to copy

Throws:

IllegalArgumentException - Incorrect Node Type

Method Details

hasLocalColors

public boolean hasLocalColors()

Specified whether this node has color information. If so, then it will be used for diffuse terms instead of materials.

Specified by:

hasLocalColors in interface VRMLGeometryNodeType

Overrides:

hasLocalColors in class BaseComponentGeometryNode

Returns:

true Use local color information for diffuse lighting.

addLocalColorsListener

public void addLocalColorsListener(LocalColorsListener l)

Add a listener for local color changes. Nulls and duplicates will be ignored.

Specified by:

addLocalColorsListener in interface VRMLGeometryNodeType

Overrides:

addLocalColorsListener in class BaseComponentGeometryNode

Parameters:

l - The listener.

removeLocalColorsListener

public void removeLocalColorsListener(LocalColorsListener l)

Remove a listener for local color changes. Nulls will be ignored.

Specified by:

removeLocalColorsListener in interface VRMLGeometryNodeType

Overrides:

removeLocalColorsListener in class BaseComponentGeometryNode

Parameters:

l - The listener.

addTexCoordGenModeChanged

public void addTexCoordGenModeChanged(TexCoordGenModeListener l)

Add a listener for texture coordinate generation mode changes. Nulls and duplicates will be ignored.

Specified by:

addTexCoordGenModeChanged in interface VRMLGeometryNodeType

Overrides:

addTexCoordGenModeChanged in class BaseComponentGeometryNode

Parameters:

l - The listener.

removeTexCoordGenModeChanged

public void removeTexCoordGenModeChanged(TexCoordGenModeListener l)

Remove a listener for texture coordinate generation mode changes. Nulls will be ignored.

Specified by:

removeTexCoordGenModeChanged in interface VRMLGeometryNodeType

Overrides:

removeTexCoordGenModeChanged in class BaseComponentGeometryNode

Parameters:

l - The listener.

isSolid

public boolean isSolid()

Specifies whether a geometry object is a solid opject. If true, then back-face culling can be performed

Specified by:

isSolid in interface VRMLGeometryNodeType

Overrides:

isSolid in class BaseComponentGeometryNode

Returns:

The current value of solid

isCCW

public boolean isCCW()

Get the value of the CCW field. If the node does not have one, this will return true.

Specified by:

isCCW in interface VRMLGeometryNodeType

Overrides:

isCCW in class BaseComponentGeometryNode

Returns:

true if the vertices are CCW ordered

isLightingEnabled

public boolean isLightingEnabled()

Specifies whether this node requires lighting.

Specified by:

isLightingEnabled in interface VRMLGeometryNodeType

Overrides:

isLightingEnabled in class BaseComponentGeometryNode

Returns:

Should lighting be enabled

getFieldIndex

public int getFieldIndex(String fieldName)

Get the index of the given field name. If the name does not exist for this node then return a value of -1.

Parameters:

fieldName - The name of the field we want the index from

Returns:

The index of the field name or -1

getNodeFieldIndices

public int[] getNodeFieldIndices()

Get the list of indices that correspond to fields that contain nodes ie MFNode and SFNode). Used for blind scene graph traversal without needing to spend time querying for all fields etc. If a node does not have any fields that contain nodes, this shall return null. The field list covers all field types, regardless of whether they are readable or not at the VRML-level.

Returns:

The list of field indices that correspond to SF/MFnode fields or null if none

getFieldDeclaration

public VRMLFieldDeclaration getFieldDeclaration(int index)

Get the declaration of the field at the given index. This allows for reverse lookup if needed. If the field does not exist, this will give a value of null.

Parameters:

index - The index of the field to get information

Returns:

A representation of this field's information

getNumFields

public int getNumFields()

Get the number of fields.

Returns:

The number of fields.

fieldChanged

public void fieldChanged(VRMLNodeType node,
 int index)

Notification that the field from the node has changed.

Parameters:

node - The component node that changed

index - The index of the field that has changed
