com.jme3.post.Filter

com.jme3.post.filters.CrossHatchFilter

All Implemented Interfaces:

com.jme3.export.Savable

public class CrossHatchFilter
extends com.jme3.post.Filter

A Post Processing filter that makes the screen look like it was drawn as diagonal lines with a pen. Try combining this with a cartoon edge filter to obtain manga style visuals. Based on an article from Geeks3D: http://www.geeks3d.com/20110219/shader-library-crosshatching-glsl-filter/
