CartoonEdge, Posterization, and CrossHatch (from the com.jme3.post.filters package) are three examples of artistic filters. In contrast to the other photo-realistic filters, artistic filters make the 3D scene look flat and untextured, as if painted or printed.

The following screenshot shows how a toon shader makes the fiercest dinosaur look cute:

The toon effect is activated just like any other filter:

  1. Make a copy of Main.java and name the class Cartoon.java. Remember to also refactor the first line of the main() method to Cartoon app = new Cartoon().

  2. Add three class fields: one for the scene, one for the FilterPostProcessor, and one for the CartoonEdgeFilter (from the com.jme3.post.filters package):

    private Spatial sceneGeo;
    private FilterPostProcessor fpp;
    private CartoonEdgeFilter toon;
  3. Initialize fpp and toon in the simpleInitApp() method. Add the FilterPostProcessor to the viewPort, and add the CartoonEdgeFilter to the FilterPostProcessor:
