• derived nodes inherit all messages from their base classes
  
• see reset method for default settings
  
• lower depth values result in higher visual priority
  
• you must add the following to your .ygrc file in order to use this node:
  
  • setenv YG_PRELOAD_CLASSES visualPriority
    

constructor visualPriority

1 allocate shared memory data structure for pre and post callbacks
2 distribute the off state of the visualPriority buffer
3 distribute the visualPriority depth

destructor ~visualPriority

method reset

1 clear nodeNames string

method message

1 set the visual priority
2 turn the priority on
3 turn the priority off

method preDrawFunc

1 cast the traversal data as the priorityData structure
2 if the plane is active then

method postDrawFunc
