I have the following Branch group for the View Platform side of the
scene graph:
VP ------------ Viewa ----------- Canvas3Da
|
|
Viewb ---------- Canvas3Db
|
|
Canvas3Dc (Off screen canvas)
The Canvas3Da node and its View node represents an alternative view
of the 3D world is created thus:
// Create a second view on the second canvas, attach it to
// the viewing platform
View viewb = new View();
viewb.setWindowResizePolicy( View.VIRTUAL_WORLD );
View view0 = canvas3Db.getView();
viewb.setPhysicalBody( view0.getPhysicalBody() );
viewb.setPhysicalEnvironment( view0.getPhysicalEnvironment() );
viewb.attachViewPlatform( canvas3Db.getViewPlatform() );
viewb.addCanvas3D( canvas3Da );
The Canvas3Db is the "main" view of the world and Canvas3Dc is an
off screen canvas to support screen capture.
The Canvas3Dc is attached to the Canvas3Db View with:
canvas3Db.getView().addCanvas3D(canvas3Dc);
I am attempting to capture a snapshot of the canvas3Db using the off screen
canvas, canvas3Dc, with :
BufferedImage image = new
BufferedImage(width,height,BufferedImage.TYPE_INT_ARGB);
ImageComponent2D buffer = new
ImageComponent2D(ImageComponent.FORMAT_RGBA, image);
buffer.setCapability(ImageComponent2D.ALLOW_IMAGE_READ);
canvas3Dc.setOffScreenBuffer(buffer);
canvas3Dc.renderOffScreenBuffer();
canvas3Dc.waitForOffScreenRendering(); <-- At this point my
program goes CPU hog and never returns.
Can any one see any problems in what I'm trying to do?
Brad.
