Hi,
just out of interest: the source code for Viewer shows lots of TODOs in the
Constructor!? Why that? Not that I am in need of the features that are left to
do, but I was wondering if the class-files are missing this feature as well or
if it is implemented there.
/**
* Creates a default viewer object. The default values are used to create
* the PhysicalEnvironment. The View is created
* with a front clip distance of 0.1f and a back clip distance of 10.0f.
*
* @param userCanvas The Canavs3D object to render to. If this object is
* null a single RGB, double buffered and depth buffered Canvas3D
* object is created.
* @param userConfig The URL of the user configuration file used to
* initialize the PhysicalBody object. If null, the default PhysicalBody
* values are used.
*/
public Viewer(Canvas3D userCanvas, URL userConfig) {
// Only one PhysicalBody per Universe.
if (physicalBody == null) {
physicalBody = new PhysicalBody();
if (userConfig != null) {
// TODO:open config file and set PhysicalBody attr's here
}
}
// Only one PhysicalEnvironment per Universe.
if (physicalEnvironment == null) {
physicalEnvironment = new PhysicalEnvironment();
// TODO:open system config file and set PhysicalEnvironment here
}
// Create Canav3D object if none was passed in.
if (userCanvas == null) {
// Canvas3D should be array, determined by GraphicsEnvironment
// and config files
GraphicsConfiguration config =
SimpleUniverse.getPreferredConfiguration();
canvas = new Canvas3D(config);
// If no canvas was provided need to also create the Frame
// and Panel for the Canvas3D.
j3dFrame = new Frame();
j3dFrame.setLayout(new BorderLayout());
// TODO: want config option to allow for full screen.
j3dFrame.setSize(256, 256);
// Put the Canvas3D into a Panel.
j3dPanel = new Panel();
j3dPanel.setLayout(new BorderLayout());
j3dPanel.add("Center", canvas);
j3dFrame.add("Center", j3dPanel);
j3dFrame.show();
// Add windowListener to detect window close event.
j3dFrame.addWindowListener(new WindowAdapter()
{
public void windowClosing(WindowEvent winEvent)
{
System.exit(0);
}
});
}
else
canvas = userCanvas;
// Create a View and attach the Canvas3D and the physical
// body and environment to the view.
view = new View();
view.addCanvas3D(canvas);
view.setPhysicalBody(physicalBody);
view.setPhysicalEnvironment(physicalEnvironment);
}
