,Steppable
Display3D's constructor takes a height and width, which is the height and width of the underlying display area (not including the button bar at-top). Display3D can be placed in a JFrame; indeed it provides a convenience function to sprout its own JFrame with the method createFrame(). You can put Display3D in your own JFrame if you like, but you should try to call Display3D.quit() when the frame is disposed.
The viewing area is by default set to roughly encapsulate a 2 by 2 by 2 cube centered at the origin. The user's eye is on the positive Z axis outside of the cube area and is looking down the negative Z axis.
Display3D can have both SimplePortrayal3Ds and FieldPortrayal3Ds attached. Once the Portrayals are attached, the you can transform them (rotate, scale, translate, etc.) all together as one scene via a Global Model Transform. Various Display3D functions are provided to manipulate this Transform (such as rotate(...)). Java3Ders in-the-know can also provide the actual Transform3D if they're feeling lucky.
Display3D provides the optional ability for the user to show axes and a backdrop. Axes are in the X, Y, and Z directions for one unit in length, and are added to the scene after the Global Model Transform has been applied. Thus if you've used the Global Model Transform to scale down your simulation into the space of a 2 by 2 by 2 cube centered at the origin, for example, the axes will just touch the edges of the cube. The backdrop is an optional feature that the programmer must add. You can provide either a spherical backdrop which rotates with the world (like a star field) or a flat backdrop which is always behind the environment and which fills the window exactly. Spherical backdrops can be wrapped with images (use a spherical projection) or -- for the daring Java3Ders -- Apperance objects. Flat backdrops can have images or flat colors.
Display3D and Java3D
Display3D uses Java3D to do its magic. Java3D is a sophisticated scene graph library, but we have done our best to hide this from you if you don't wish to know anything about how Java3D works. For those experienced in Java3D, we describe here the top-level scene graph used by the Display3D.
The Unverse is a SimpleUnverse called universe, the top BranchGraph is root, and the Canvas3D is a special subclass (CapturingCanvas3D) called canvas. A CapturingCanvas3D contains some additional machinery to make possible snapshots and movies. If you wish to add some scene graph material outside of Portrayal3Ds, and you don't want it to be transformed by the Global Model Transform, nor do you want it to be auto-spinnable, hanging it off of root is a good location. Note that even so, the user will be able to rotate, zoom, magnify, and translate the world with the mouse, and that includes this extra scene graph material.
Hanging off of root are two pairs of TransformGroups and RotationInterpolators responsible for auto-spinning the scene graph and a spherical backdrop (a Background object, if one exists), respectively. Auto-spinning happens in concert in these two TransformGroups, so the backdrop will always appear to be auto-spinning with the scene graph.
One of these TransformGroups (autoSpinTransformGroup) is public and holds the scene graph. The other TransformGroup is private. autoSpinTransformGroup is a good place to hang extra scene graph stuff you wish to add, if you don't want that stuff to be transformed along with the Portrayal3Ds, but you'd like it to be auto-spun along with the Portrayal3Ds.
Hanging off of autoSpinTransformGroup are two items: a private Switch which turns on and off the optional axes and backdrop; and globalModelTransformGroup, the TransformGroup responsible for transforming all of the Portrayals in the scene according to the global model transform. Additionally, globalModelTransformGroup is a good place to hang extra scene graph stuff you wish to add that you want to be transformed by the global model transform along with the rest of the Portrayal3Ds.
The globalModelTransformGroup in turn holds a private Switch which in turn holds the scene graph material supplied by each of the Portrayal3Ds in the scene. This Switch turns the Portrayals on and off according the layers menu choice the user makes on the button bar.
The LightSwitch, which resides in a BranchGrouop hanging of the ViewPlatform's TransformGroup node (where the camera is), holds two lights, a PointLight and an AmbientLight, which may be turned on or off by the user. You can change these lights if you like.
The right place to add scene graph material, or make other changes to the Java3D environment, is in the sceneGraphCreated() hook. This function is called for your benefit after the Display3D has created its scene graph material but just before the renderer has been started -- thus the graph is not yet online and is still modifiable.
If you add extra scene graph material to the Display3D outside of a Portrayal3D context, you should set it to be unpickable, or otherwise you will get errors when the user tries to select it from the scene (Display3D uses geometry-based picking for its object selection). The easiest way for you to do this to a given node is to call the utility function sim.display3d.SimpleDisplay3D.clearPickableFlags(node)

scale
public void scale(double sx, double sy, double sz) Modifies the internal transform by scaling it in a nonuniform fashion. Note that this is less efficient than a uniform scale. Has nothing to do with the setScale(...) and getScale(...) methods. -
destroySceneGraph
public void destroySceneGraph()Eliminates the existing scene graph. This ought to be called when starting a simulation prior to creating any new Portrayal3Ds. The reason is simple: if the Portrayal3Ds use shared geometry objects underneath, then creating them may create new shared geometry objects, which isn't permitted if there are existing shared geometry objects in a live scene graph. So destroy the scene graph, create the new objects, and recreate the scene graph, and you're set. -
createSceneGraph
public void createSceneGraph()Recreates the entire scene graph, including the universe, root, and canvas3d. This is an expensive procedure and generally should only be called when starting a simulation (in GUIState's start() or load() methods). Just before the renderer is started and the scene goes online, the hook sceneGraphCreated() is called in case you'd like to add anything to the scene graph. -
sceneGraphCreated
protected void sceneGraphCreated()A hook for people who want to modify the scene graph just after it's been created (when the user pressed the start button usually; or if the user dynamicallly attaches or detaches portrayals) but before the root has been attached to the universe and before the canvas has started rendering. Override this as you see fit. The default does nothing at all. -
setScale
public void setScale(double val) Changes the value of the scale (magnification). Usually done by the user through changing the value of the Scale text field. This has nothing to do with the scale() method. -
getScale
public double getScale()Returns the value of the scale (magnification). This has nothing to do with the scale() method. -
getSelectionBehavior
-
getToolTipBehavior
-
setSelectsAll
public void setSelectsAll(boolean selection, boolean inspection) Sets whether mouse-clicking results in selecting all picked elements (true) or just the closest one (false). This can be done independently of selection and inspection. By default these values are both TRUE. -
paintComponent
Updates the scene graph- Overrides:

-
takeSnapshot
public void takeSnapshot()Takes a snapshot of the Display3D's currently displayed simulation. Ought only be done from the main event loop. -
startMovie
public void startMovie()Starts a Quicktime movie on the given Display3D. The size of the movie frame will be the size of the display at the time this method is called. This method ought to be called from the main event loop. Most of the default movie formats provided will result in a giagantic movie, which you can re-encode using something smarter (like the Animation or Sorenson codecs) to put to a reasonable size. On the Mac, Quicktime Pro will do this quite elegantly. -
stopMovie
public void stopMovie()Stops a Quicktime movie and cleans up, flushing the remaining frames out to disk. This method ought to be called from the main event loop. -
quit
public void quit()Quits the Display3D. Called by the Display3D's frame if the Display3D made the frame itself. Also called by finalize(). Otherwise you should call this method before destroying the Display3D. -

setCullingMode
public void setCullingMode(int mode) -
