public class NRViewpoint
extends BaseViewpoint
implements NRVRMLNode

Null renderer implementation of a Viewpoint node.

VRML requires the use of a headlight from the NavigationInfo node. For convenience, we provide a headlight here that binds with the same transform as the view platform.

Viewpoints cannot be shared using DEF/USE. They may be named as such for Anchor purposes, but attempting to reuse them will cause an error. This implementation does not provide any protection against USE of this node and attempting to do so will result in Java3D throwing exceptions - most probably in the grouping node that includes this node.

Constructor Details

NRViewpoint

public NRViewpoint()

Construct a default viewpoint instance

NRViewpoint

public NRViewpoint(VRMLNodeType node)

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

Parameters:

node - The node to copy

Throws:

IllegalArgumentException - The node is not the same type
