The SDK allows you to create combinations of filters and preview them on a loaded scene.
To create a new filter:
To see a loaded filter, you have to load some model or scene and press the "show filter" button in the OpenGL window.
You can add a new filter by right-clicking the filter root node. Select a filter to see its properties in the properties window.
To load a filter in a game and add it to a viewport add the following to your games simpleInit() method or some other place:
FilterPostProcessor processor = (FilterPostProcessor) assetManager.loadAsset("Filters/MyFilter.j3f"); viewPort.addProcessor(processor);
