Bump Map uses colors in the image to imitate small displacement on the surface of a 3D object. It's a great way to add small texture details to 3D objects. It saves you the great effort of describing them in 3D terminology.
For example, take a look at the next bump map image and the 3D object affected by it:
To achieve that, you need to call material.setBumpMap(Image bumpImage):
PhongMaterial material= new PhongMaterial();material.setBumpMap(new Image( "https://upload.wikimedia.org/wikipedia/commons/8/86/IntP_Brick_NormalMap.png"));Box box = new Box(100, 100, 100);box.setTranslateX(250);box.setTranslateY(100);box.setTranslateZ(400); ...
