public class ViewPlatform
extends Leaf
The ViewPlatform leaf node object controls the position, orientation and scale of the viewer. It is the node in the scene graph that a View object connects to.

Variable Index

o ALLOW_POLICY_READ
Specifies that the ViewPlatform allows read access to its view attach policy information at runtime.
o ALLOW_POLICY_WRITE
Specifies that the ViewPlatform allows write access to its view attach policy information at runtime.

Constructor Index

o ViewPlatform()

Method Index

o getActivationRadius()
Get the ViewPlatform's activation radius.
o getViewAttachPolicy()
Returns the current coexistence center in virtual-world policy.
o setActivationRadius(float)
Set the ViewPlatform's activation radius which defines an activation volume around the view platform.
o setViewAttachPolicy(int)
Sets the coexistence center in virtual world policy.

Variables

o ALLOW_POLICY_READ 
 public static final int ALLOW_POLICY_READ
Specifies that the ViewPlatform allows read access to its view attach policy information at runtime.

o ALLOW_POLICY_WRITE 
 public static final int ALLOW_POLICY_WRITE
Specifies that the ViewPlatform allows write access to its view attach policy information at runtime.

Constructors

o ViewPlatform 
 public ViewPlatform()

Methods

o setViewAttachPolicy 
 public final void setViewAttachPolicy(int policy)
Sets the coexistence center in virtual world policy. This setting determines how Java 3D places the user's eye point as a function of head position. The variable can contain one of NOMINAL_SCREEN, NOMINAL_HEAD, or NOMINAL_FEET.

Parameters:
policy - the new policy, one of NOMINAL_SCREEN, NOMINAL_HEAD, or NOMINAL_FEET
Throws: CapabilityNotSetException
if appropriate capability is not set and this object is part of live or compiled scene graph
o getViewAttachPolicy 
 public final int getViewAttachPolicy()
Returns the current coexistence center in virtual-world policy.

Returns:
one of: NOMINAL_SCREEN, NOMINAL_HEAD, or NOMINAL_FEET
Throws: CapabilityNotSetException
if appropriate capability is not set and this object is part of live or compiled scene graph
o setActivationRadius 
 public final void setActivationRadius(float activationRadius)
Set the ViewPlatform's activation radius which defines an activation volume around the view platform.

Parameters:
activationRadius - the new activation radius
o getActivationRadius 
 public final float getActivationRadius()
Get the ViewPlatform's activation radius.

Returns:
the ViewPlatform activation radius
