Class TestRenderToMemory

java.lang.Object

com.jme3.app.LegacyApplication

com.jme3.app.SimpleApplication

jme3test.post.TestRenderToMemory

All Implemented Interfaces:

Application, SceneProcessor, SystemListener

public class TestRenderToMemory
extends SimpleApplication
implements SceneProcessor

This test renders a scene to an offscreen framebuffer, then copies the contents to a Swing JFrame. Note that some parts are done inefficiently, this is done to make the code more readable.
