Starts traversing this view, and starts the renderers associated with all canvases attached to this view.

Usage

From source file:OffScreenTest.java

public void init() {
    setLayout(new BorderLayout());
    GraphicsConfiguration config = SimpleUniverse.getPreferredConfiguration();

    BufferedImage bImage = new BufferedImage(200, 200, BufferedImage.TYPE_INT_ARGB);

    ImageComponent2D buffer = new ImageComponent2D(ImageComponent.FORMAT_RGBA, bImage);
    buffer.setCapability(ImageComponent2D.ALLOW_IMAGE_READ);

    Raster drawRaster = new Raster(new Point3f(0.0f, 0.0f, 0.0f), Raster.RASTER_COLOR, 0, 0, 200, 200, buffer,
            null);/*from ww  w .j av  a 2  s .co m*/

    drawRaster.setCapability(Raster.ALLOW_IMAGE_WRITE);

    // create the main scene graph
    BranchGroup scene = createSceneGraph(drawRaster);

    // create the on-screen canvas
    OnScreenCanvas3D d = new OnScreenCanvas3D(config, false);
    add("Center", d);

    // create a simple universe
    u = new SimpleUniverse(d);

    // This will move the ViewPlatform back a bit so the
    // objects in the scene can be viewed.
    u.getViewingPlatform().setNominalViewingTransform();

    // create an off Screen Canvas

    OffScreenCanvas3D c = new OffScreenCanvas3D(config, true, drawRaster);

    // set the offscreen to match the onscreen
    Screen3D sOn = d.getScreen3D();
    Screen3D sOff = c.getScreen3D();
    sOff.setSize(sOn.getSize());
    sOff.setPhysicalScreenWidth(sOn.getPhysicalScreenWidth());
    sOff.setPhysicalScreenHeight(sOn.getPhysicalScreenHeight());

    // attach the same view to the offscreen canvas
    View v = u.getViewer().getView();
    v.addCanvas3D(c);

    // tell onscreen about the offscreen so it knows to
    // render to the offscreen at postswap
    d.setOffScreenCanvas(c);

    u.addBranchGraph(scene);
    v.stopView();
    // Make sure that image are render completely
    // before grab it in postSwap().
    d.setImageReady();
    v.startView();
