SpotLight example code

  • Create a light 
    SpotLight myLight = new SpotLight( );
myLight.setEnable( true );
myLight.setColor( new Color3f( 1.0f, 1.0f, 1.0f ) );
myLight.setPosition( new Point3f( 0.0f, 1.0f, 0.0f ) );
myLight.setAttenuation( new Point3f( 1.0f, 0.0f, 0.0f ) );
myLight.setDirection( new Vector3f( 1.0f, 0.0f, 0.0f ) );
myLight.setSpreadAngle( 0.785f ); // 45 degrees
myLight.setConcentration( 3.0f ); // Unfocused

  • Set its influencing bounds 
    BoundingSphere myBounds = new BoundingSphere(
    new Point3d( ), 1000.0 );
myLight.setInfluencingBounds( myBounds );
