geomData

protected org.j3d.geom.GeometryData geomData

Userdata kept in the triangle geometry

Constructor Details

BaseTriangleGeometryNode

protected BaseTriangleGeometryNode(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 Details

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 propagate 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

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

Description copied from interface: VRMLNodeType

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.

Overrides:

setNormalNode in class BaseComponentGeometryNode

Parameters:

node - The node to use

fieldChanged

public void fieldChanged(VRMLNodeType node,
 int index)

Description copied from interface: VRMLNodeComponentListener

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

updateCoordinateArray

protected void updateCoordinateArray()

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

updateNormalArray

protected void updateNormalArray()

Update the normal array in geomData based on the normal node and normalPerVertex flag.

updateColorArray

protected void updateColorArray()

Update the normal array in geomData based on the normal node and normalPerVertex flag.
