sim.display3d.Display3D
Display3D holds, displays, and manipulates 3D Portrayal objects, allowing the user to scale them, rotate them, translate them, magnify them, change how often they're updated, take snapshots, and generate Quicktime movies. Display3D is Steppable, and each time it is stepped it updates and redisplays itself. Display3D also handles double-click events, routing them to the underlying portrayals as inspector requests.
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 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 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)
