How to use PointLight E-mail
User Rating: / 3
PoorBest 

The PointLight is the conceptual opposite of a DirectionalLight. It is an omni-directional light source whose intensity attenuates with distance and has location. (A DirectionalLight source has no location, just a direction.) PointLight objects approximate bare light bulbs, candles, or other light sources without reflectors or lenses.

public class PointLightExample extends JFrame{

        //Define the PointLight object
    private PointLight light=new PointLight();
    
    ...
  
    BranchGroup createScene() {
        BranchGroup scene=new BranchGroup();
    
        scene.addChild(new Sphere(0.4f));
    
        // Config the light
         light.setCapability(PointLight.ALLOW_POSITION_WRITE);
        light.setColor(new Color3f(Color.RED));
        light.setPosition(0.0f,1.0f,0.0f);
        light.setInfluencingBounds(new BoundingSphere());
        // Add the light
        scene.addChild(light);
    
        scene.compile();
    
        return scene;
    }
    
    ...
}
