ParsingErrorException

Method Detail

getParent

int getParent()

Returns parent of the camera object

createJava3dObject

void createJava3dObject(int loadBehaviors)

Creates Java3D items from the camera data. These objects consist of: a TransformGroup to hold the view platform, and the behaviors (if any) that act upon the view's TransformGroup.

getObjectNode

public TransformGroup getObjectNode()

Returns TransformGroup of camera

Specified by:

getObjectNode in interface LwsPrimitive

getObjectBehaviors

public java.util.Vector getObjectBehaviors()

Returns animation behaviors for camera

Specified by:

getObjectBehaviors in interface LwsPrimitive

printVals

void printVals()

This is a debuggin utility, not currently activated. It prints out the camera values
