Time for action – let the sun shine in

The light scattering filter is another example of an effect that uses the post-processor that we are already familiar with from a previous chapter.

1. Make a copy of Main.java and name the class SunLight.java. Remember to also refactor the first line of the main() method to the following:

   SunLight app = new SunLight();

2. Specify the direction of the sunlight as a vector.

     private Vector3f lightDir = new Vector3f(-0.39f, -0.32f, -0.74f);

3. Create one FilterPostProcessor per game, and a LightScatteringFilter.

     private FilterPostProcessor fpp;
     private LightScatteringFilter sunLightFilter;

4. Use the lightDir vector to create a DirectionalLight and add it to the rootNode.

    public void simpleInitApp() { DirectionalLight sun = new ...
