Hallo, When i want to render a onscreen canvas i use the command renderOnce() to make sure that the frame that i want is rendered. If i use an offscreen canvas i use the comand waitForOffScreenRendering();
the explication in the java 3d API: http://java.sun.com/products/java- media/3D/forDevelopers/J3D_1_2_API/j3dguide/ViewModel.doc.html #55510 -public void renderOnce() This method renders one frame for a stopped View. Functionally, this method is equivalent to startView() followed by stopview(), except that it is atomic, which guarantees that only one frame is rendered -public void waitForOffScreenRendering() This method waits for this Canvas3D's off-screen rendering to be done. This method will wait until the postSwap method of this off-screen Canvas3D has completed. If this Canvas3D has not been added to an active view or if the renderer is stopped for this Canvas3D, this method will return immediately. This method must not be called from a render callback method of an off-screen Canvas3D So, onscreen canvas 3d: canvas3D.getView().stopView(); canvas3D.getView().renderOnce(); canvas3D.getView().startView(); offscreen canvas 3d offCanvas.renderOffScreenBuffer(); offCanvas.waitForOffScreenRendering(); I dont know if this is the best approach but it works good for me. I would not use a thread to do it too, but if you need to do with a thread, i hoppe that this will work. Tiago > Hi Java 3D fans > > I do a simulation.
