Constructor Details

OGLVisibilitySensor

public OGLVisibilitySensor()

Construct a new visibility sensor object

OGLVisibilitySensor

public OGLVisibilitySensor(VRMLNodeType node)

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

Parameters:

node - The node to copy

Throws:

IllegalArgumentException - The node is not the right type

Method Details

setEnabled

public void setEnabled(boolean state)

Set the sensor enabled or disabled.

Specified by:

setEnabled in interface VRMLSensorNodeType

Overrides:

setEnabled in class BaseSensorNode

Parameters:

state - true if the sensor is to be enabled

getSceneGraphObject

public org.j3d.aviatrix3d.SceneGraphObject getSceneGraphObject()

Get the OpenGL scene graph object representation of this node. This will need to be cast to the appropriate parent type when being used.

Specified by:

getSceneGraphObject in interface OGLVRMLNode

Returns:

The OGL representation.

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 AbstractNode

visibilityStateChange

public void visibilityStateChange(boolean visible,
 javax.vecmath.Point3f position,
 javax.vecmath.AxisAngle4f orientation,
 javax.vecmath.Matrix4f localPosition)

Invoked when the user enters or leaves an area.

Specified by:

visibilityStateChange in interface OGLVisibilityListener

Parameters:

visible - true when the user enters the area

position - The position of the user on entry/exit

orientation - The orientation of the user there

localPosition - The vworld transform object for the class that implemented this listener

viewPositionChanged

public void viewPositionChanged(javax.vecmath.Point3f position,
 javax.vecmath.AxisAngle4f orientation,
 javax.vecmath.Matrix4f localPosition)

Notification that the object is still visible, but that the viewer reference point has changed. Ignored for this implementation.

Specified by:

viewPositionChanged in interface OGLVisibilityListener

Parameters:

position - The new position of the user

orientation - The orientation of the user there

localPosition - The vworld transform object for the class that implemented this listener

setVRMLClock

public void setVRMLClock(VRMLClock clk)

Set the vrmlClock that this time dependent node will be running with.

Specified by:

setVRMLClock in interface VRMLTimeDependentNodeType

Overrides:

setVRMLClock in class BaseVisibilitySensor

Parameters:

clk - The vrmlClock to use for this node

setSize

protected void setSize(float[] val)

Update the size of the sensor. May be overridden by derived classes but should make sure to call this as well

Overrides:

setSize in class BaseVisibilitySensor

Parameters:

val - The new size to use

setCenter

protected void setCenter(float[] val)

Update the center of the sensor. May be overridden by derived classes but should make sure to call this as well

Overrides:

setCenter in class BaseVisibilitySensor

Parameters:

val - The new center to use

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.

Specified by:

allEventsComplete in interface FrameStateListener

Overrides:

allEventsComplete in class AbstractNode

updateNodeBoundsChanges

public void updateNodeBoundsChanges(Object src)

Notification that its safe to update the node now with any operations that could potentially effect the node's bounds.

Specified by:

updateNodeBoundsChanges in interface org.j3d.aviatrix3d.NodeUpdateListener

Parameters:

src - The node or Node Component that is to be updated.

updateNodeDataChanges

public void updateNodeDataChanges(Object src)

Notification that its safe to update the node now with any operations that only change the node's properties, but do not change the bounds.

Specified by:

updateNodeDataChanges in interface org.j3d.aviatrix3d.NodeUpdateListener

Parameters:

src - The node or Node Component that is to be updated.
