Description

Interface Summary

InputRequester	An interface to start and stop the various input events available.
InteractiveOverlay	An extended version of the overlay that would like to have interactive input from the mouse and/or keyboard.
Overlay	An overlay is rectangular texture which is aligned with the image plate giving the illusion of an image drawn onto the canvas rather than in the scene.
ScreenComponent	A representation of something that can be seen on screen.
ScrollEventListener	A listener for scroll events.
UpdatableEntity	A representation of an entity that requires periodic updates.
UpdateManager	A representation of a manager that processes updates.

Class Summary

ImageButtonOverlay	An overlay with a clickable image that acts like a button.
ImageOverlay	An overlay that draws an image on screen at the given position.
InteractiveOverlayBase	An implementation of the interactive overlay.
InteractiveTextureOverlay	An texture overlay extension that allows input events to be captured.
LabelOverlay	An overlay that renders a text label.
MouseOverlay	An overlay that is used like an ordinary drawing canvas that interacts with the mouse.
OverlayBase	An implementation of the overlay and screen component interfaces to provide a ready-made overlay system.
OverlayManager	The overlay manager keeps track of all the overlay's on the screen and makes sure they are updated with the view transform once a frame.
OverlayUtilities	Utility functionality for creating parts of the overlay system.
ScribbleOverlay	An overlay allows the user to scribble on the screen, over the top of the 3D display.
ScrollEvent	An event describing a scroll action or request.
TextureOverlay	An overlay implementation that uses a Java3D Texture2D object for the renderable surface.
UpdateControlBehavior	An implementation of an update manager that uses the Java3D behaviour system.

Package org.j3d.renderer.java3d.overlay Description

Classes for providing 2D screen overlays for a 3D canvas.

Overlays provide an application with the ability place a 2D set of rendered images over the top of the 3D scene. This has come about because of the dismal performance of the standard Java3D capability provided by the Canvas3D class. These overlays are oriented as part of the 3D and always consistent with any drawn parts to provide an invisible overlay capability to the application code.
