Constructor Detail

BaseIndexedTriangleGeometryNode

protected BaseIndexedTriangleGeometryNode(java.lang.String name)

Construct a default instance of this class with the bind flag set to false and no time information set (effective value of zero).

Parameters:

name - The name of the type of node

Method Detail

copy

protected void copy(VRMLComponentGeometryNodeType node)

Set the fields of the binadble node that has the fields set based on the fields of the passed in node. This directly copies the bind state, so could cause some interesting problems. Not sure what we should do with this currently.

Overrides:

copy in class BaseComponentGeometryNode

Parameters:

node - The bindable node to copy info from

buildImpl

protected abstract void buildImpl()

Build the render specific implementation.

allEventsComplete

public void allEventsComplete()

Notification that the rendering of the event model is complete and that rendering is about to begin. Used to update the transformation matrix only once per frame. If the derived class needs to propogate the changes then it should override the updateMatrix() method or this and make sure this method is called first.

Specified by:

allEventsComplete in interface FrameStateListener

Overrides:

allEventsComplete in class AbstractNode

getFieldValue

public VRMLFieldData getFieldValue(int index)
                            throws InvalidFieldException

Get the value of a field. If the field is a primitive type, it will return a class representing the value. For arrays or nodes it will return the instance directly.

Specified by:

getFieldValue in interface VRMLNodeType

Overrides:

getFieldValue in class BaseComponentGeometryNode

Parameters:

index - The index of the field to change.

Returns:

The class representing the field value

Throws:

InvalidFieldException - The field index is not known

sendRoute

public void sendRoute(double time,
                      int srcIndex,
                      VRMLNodeType destNode,
                      int destIndex)

Send a routed value from this node to the given destination node. The route should use the appropriate setValue() method of the destination node. It should not attempt to cast the node up to a higher level. Routing should also follow the standard rules for the loop breaking and other appropriate rules for the specification.

Specified by:

sendRoute in interface VRMLNodeType

Overrides:

sendRoute in class BaseComponentGeometryNode

Parameters:

time - The time that this route occurred (not necessarily epoch time. Should be treated as a relative value only)

srcIndex - The index of the field in this node that the value should be sent from

destNode - The node reference that we will be sending the value to

destIndex - The index of the field in the destination node that the value should be sent to.

setValue

public void setValue(int index,
                     int[] value,
                     int numValid)
              throws InvalidFieldException,
                     InvalidFieldValueException,
                     InvalidFieldAccessException

Set the value of the field at the given index as an array of integers. This would be used to set MFInt32 field types.

Specified by:

setValue in interface VRMLNodeType

Overrides:

setValue in class AbstractNode

Parameters:

index - The index of destination field to set

value - The new value to use for the node

numValid - The number of valid values to copy from the array

Throws:

InvalidFieldException - The index does not match a known field

InvalidFieldValueException - The value provided is out of range for the field type.

InvalidFieldAccessException - The call is attempting to write to a field that does not permit writing now

setupFinished

public void setupFinished()

Notification that the construction phase of this node has finished. If the node would like to do any internal processing, such as setting up geometry, then go for it now.

Specified by:

setupFinished in interface VRMLNodeType

Overrides:

setupFinished in class BaseComponentGeometryNode

notifyExternProtoLoaded

public void notifyExternProtoLoaded(int index,
                                    VRMLNodeType node)
                             throws InvalidFieldValueException

Notify a node that an ExternProto has resolved. This will verify the objects type and add it to the render sceneGraph.

Specified by:

notifyExternProtoLoaded in interface VRMLNodeType

Overrides:

notifyExternProtoLoaded in class AbstractNode

Parameters:

index - The field index

node - The node resolved

Throws:

InvalidFieldValueException - If the proto contains he wrong type

setValue

public void setValue(int index,
                     VRMLNodeType child)
              throws InvalidFieldException,
                     InvalidFieldValueException

Set the value of the field at the given index as a node. This would be used to set SFNode field types.

Specified by:

setValue in interface VRMLNodeType

Overrides:

setValue in class BaseComponentGeometryNode

Parameters:

index - The index of destination field to set

child - The new value to use for the node

Throws:

InvalidFieldException - The field index is not known

InvalidFieldValueException - The node does not match the required type.

setCoordinateNode

protected void setCoordinateNode(VRMLCoordinateNodeType node)

Notification of the coordinate node being set. If the passed value is null then that clears the node. The node passed is the actual geometry, not any proto wrapper, that will have been previously stripped. The default implementation does nothing.

Overrides:

setCoordinateNode in class BaseComponentGeometryNode

Parameters:

node - The node to use

setColorNode

protected void setColorNode(VRMLColorNodeType node)

Notification of the color node being set. If the passed value is null then that clears the node. The node passed is the actual color, not any proto wrapper, that will have been previously stripped. The default implementation does nothing.

Overrides:

setColorNode in class BaseComponentGeometryNode

Parameters:

node - The node to use

setTextureCoordinateNode

protected void setTextureCoordinateNode(VRMLTextureCoordinateNodeType node)

Notification of the coordinate node being set. If the passed value is null then that clears the node. The node passed is the actual geometry, not any proto wrapper, that will have been previously stripped. The default implementation does nothing.

Parameters:

node - The node to use

setNormalNode

protected void setNormalNode(VRMLNormalNodeType node)

Notification of the color node being set. If the passed value is null then that clears the node. The node passed is the actual color, not any proto wrapper, that will have been previously stripped. The default implementation does nothing.

node - The node to use

fieldChanged

public void fieldChanged(VRMLNodeType node,
                         int index)

index - The index of the field that has changed

setIndex

protected void setIndex(int[] value,
                        int numValid)

Set the index field. Override to provide.renderer-specific behaviour, but remember to also call this implementation too.

Parameters:

value - The list of index values to use

numValid - The number of valid values to copy from the array

updateCoordinateArray

protected void updateCoordinateArray()

Update the coordinate array in geomData based on the coordinate data.

updateNormalArray

protected void updateNormalArray()
