Time for action – no frills, just color

First we create an illuminated sphere with a blue material, using a normal geometry with a material based on the Lighting.j3md material definition:

1. Make a copy of Main.java and name the class MaterialColor.java. Remember to also refactor the first line of the main() method to MaterialColor app = new MaterialColor ();.
2. Replace the blue cube code in the simpleInitApp() method with the following:

   Sphere sphereMesh = new Sphere(32,32, 1f); Geometry sphereGeo = new Geometry("Colored lit sphere", sphereMesh); Material sphereMat = new Material(assetManager, "Common/MatDefs/Light/Lighting.j3md"); sphereMat.setBoolean("UseMaterialColors", true); sphereMat.setColor("Diffuse", ColorRGBA.Blue ); sphereMat.setColor("Ambient", ...
