 Light3D

（1）首先：设置舞台背景的默认光色

scene.clearColor.setTo( 0, 0, 0 );　　　　//舞台的背景色

scene.lights.ambientColor.setTo( 0, 0, 0 );　　//场景光色

scene.defaultLight = null;　　//关闭引擎默认灯光
 

（2）注册灯光：a.可以获得模型内已有的灯    b.也可以自己new一个Light3D

var light1:Light3D = new Light3D();   

scene.addChild( light );

light2 = scene.getChildByName( "Omni032" ) as Light3D;

light.setPosition( 1000, 1000, -1000 );

（3）要确定灯光的类型： PointLight 或者 DirectionalLight

scene.lights.maxPointLights = 0;  

scene.lights.maxDirectionalLights = 0;　　　 

（4）// swith between diferent light configurations. 
if ( Input3D.keyHit( Input3D.NUMBER_1 ) ) scene.lights.techniqueName = LightFilter.NO_LIGHTS;
if ( Input3D.keyHit( Input3D.NUMBER_2 ) ) scene.lights.techniqueName = LightFilter.PER_VERTEX;
if ( Input3D.keyHit( Input3D.NUMBER_3 ) ) scene.lights.techniqueName = LightFilter.LINEAR;
if ( Input3D.keyHit( Input3D.NUMBER_4 ) ) scene.lights.techniqueName = LightFilter.SAMPLED;
