Directional Lights

• DirectionalLight extends the Light class

• Light rays are parallel and aim in one direction

• Use directional lights to simulate distant lights, like the Sun

void setDirection( Vector3f dir )

0.0, 0.0, -1.0 

TransformGroup group = new TransformGroup( );
. . .
DirectionalLight light = new DirectionalLight( );
light.setEnable( true );
light.setColor( new Color3f( 1.0f, 1.0f, 1.0f ) );
light.setDirection( new Vector3f( 1.0f, 0.0f, 0.0f ) );
. . .
light.setInfluencingBounds( bounds );
group.addChild( light );
