org.piccolo2d.PNode

org.piccolo2d.PCamera

All Implemented Interfaces:

Printable, Serializable, Cloneable

public class PCamera
extends PNode

PCamera represents a viewport onto a list of layer nodes. Each camera maintains a view transform through which it views these layers. Translating and scaling this view transform is how zooming and panning are implemented.

Cameras are also the point through which all PInputEvents enter Piccolo. The canvas coordinate system and the local coordinate system of the topmost camera should always be the same.
