public class CameraNode
- extends Node
CameraNode
defines a node that contains a camera object. This
allows a camera to be controlled by any other node, and allows the camera to
be attached to any node. A call to updateWorldData
will adjust
the camera's frame by the world translation and the world rotation. The
column 0 of the world rotation matrix is used for the camera left vector,
column 1 is used for the camera up vector, column 2 is used for the camera
direction vector.

CameraNode
public CameraNode()
CameraNode
public CameraNode(java.lang.String name,
Camera camera)
- Constructor instantiates a new
CameraNode
object setting
the camera to use for the frame reference.
- Parameters:
name
- the name of the scene element. This is required for
identification and comparision purposes.camera
- the camera this node controls.
updateFromCamera
public void updateFromCamera()
- Forces rotation and translation of this node to be consistant with the
attached camera. (Assumes the node is in world space.)
setCamera
public void setCamera(Camera camera)
setCamera
sets the camera that this node controls.
- Parameters:
camera
- the camera that this node controls.
getCamera
public Camera getCamera()
getCamera
retrieves the camera object that this node
controls.
- Returns:
- the camera this node controls.
updateWorldData
public void updateWorldData(float time)
updateWorldData
updates the rotation and translation of
this node, and sets the camera's frame buffer to reflect the current
view.
- Overrides:
updateWorldData
in class Node
- Parameters:
time
- the time between frames.
