　　[b]使用TargetCamera： [/b]
　　Java代码
　　
　　
　　// 将camera锁定住对象mesh targetCamera = [b]new[/b] TargetCamera3D(10, 100, mesh); targetCamera.z = -1000; // 给view赋值：新的camera view.camera = targetCamera; // 将camera锁定住对象meshtargetCamera = new TargetCamera3D(10, 100, mesh);targetCamera.z = -1000;// 给view赋值：新的cameraview.camera = targetCamera;
　　[b]锁定摄像机视角： [/b]
　　Java代码
　　
　　
　　override [b]protected[/b] function onPreRender():[b]void[/b] { sphere1.x = 200*Math.sin(step); step += 0.1; target = isLookAt? sphere0 : sphere1; // flash.display.DisplayObject.tranform.matrix3D.position // 一个保存显示对象在转换参照帧中的 3D 坐标 (x,y,z) 位置的 Vector3D 对象。 camera.lookAt(target.transform.matrix3D.position); } override protected function onPreRender():void{ sphere1.x = 200*Math.sin(step); step += 0.1; target = isLookAt? sphere0 : sphere1; // flash.display.DisplayObject.tranform.matrix3D.position // 一个保存显示对象在转换参照帧中的 3D 坐标 (x,y,z) 位置的 Vector3D 对象。 camera.lookAt(target.transform.matrix3D.position);}

　　[b]遍历场景中的所有object： [/b]
　　Java代码
　　
　　
　　[b]protected[/b] override function onPreRender():[b]void[/b] { // 继承关系 Sphere -> AbstractPrimitive -> Mesh -> Object3D -> flash.display.Sprite [b]for[/b] each (var mesh:Mesh in scene.children) { mesh.rotationX++; mesh.rotationY++; mesh.rotationZ++; } } protected override function onPreRender():void{ // 继承关系 Sphere -> AbstractPrimitive -> Mesh -> Object3D -> flash.display.Sprite for each (var mesh:Mesh in scene.children) { mesh.rotationX++; mesh.rotationY++; mesh.rotationZ++; }}
　　[b]设置3D剪裁窗口大小： [/b]
　　Java代码
　　
　　
　　// 如果你在代码里设置view.width与view.height不会报错，但不会起作用 [b]private[/b] var clipping:RectangleClipping; clipping = [b]new[/b] RectangleClipping(); clipping.minX = -400; clipping.minY = -300; clipping.maxX = 400; clipping.maxY = 300; [b]private[/b] var view:View3D; view = [b]new[/b] View3D(); view.clipping = clipping; // 如果你在代码里设置view.width与view.height不会报错，但不会起作用private var clipping:RectangleClipping;clipping = new RectangleClipping();clipping.minX = -400;clipping.minY = -300;clipping.maxX = 400;clipping.maxY = 300;private var view:View3D;view = new View3D();view.clipping = clipping;
　　[b]设置layer：（同PV3D中的viewportLayer） [/b]
　　Java代码
　　
　　
　　// Plane plane = [b]new[/b] Plane([b]new[/b] BitmapFileMaterial("assets/earth.jpg"), 256, 128); plane.bothsides = [b]true[/b]; plane.rotationX = 45; plane.y = i*50 - 4*50/2; scene.addChild(plane); // Layer var layer:Sprite = [b]new[/b] Sprite(); view.addChild(layer); // Object3D.layer：An optional layer sprite used to draw into inseatd of the default view. plane.layer = layer; // Event plane.layer.addEventListener(MouseEvent.CLICK, onClick); [b]private[/b] function onClick(event:MouseEvent):[b]void[/b] { var layer:Sprite = event.target as Sprite; // 给layer添加滤镜 [b]if[/b](layer.filters.length==0) layer.filters = [[b]new[/b] GlowFilter(0xFF0000, 1, 4, 4, 16, 1)]; [b]else[/b] layer.filters = [b]null[/b]; } // Planeplane = new Plane(new BitmapFileMaterial("assets/earth.jpg"), 256, 128);plane.bothsides = true;plane.rotationX = 45;plane.y = i*50 - 4*50/2;scene.addChild(plane);// Layervar layer:Sprite = new Sprite();view.addChild(layer);// Object3D.layer：An optional layer sprite used to draw into inseatd of the default view.plane.layer = layer;// Eventplane.layer.addEventListener(MouseEvent.CLICK, onClick);private function onClick(event:MouseEvent):void{ var layer:Sprite = event.target as Sprite; // 给layer添加滤镜 if(layer.filters.length==0) layer.filters = [new GlowFilter(0xFF0000, 1, 4, 4, 16, 1)]; else layer.filters = null;}
　　[b]Cast类使用： [/b]
　　Java代码
　　
　　
　　// Cast：Helper class for casting assets to usable objects // Casts the given data value as a bitmapdata object. // 将一个图片class转化成一个bitmapdata shadeMaterial = [b]new[/b] BitmapMaterial(Cast.bitmap(Shade)); // Casts the given data value as a material object. // 将一个图片class转化成一个material对象 materialArray = [Cast.material(GreenPaint), Cast.material(RedPaint)]; // Cast：Helper class for casting assets to usable objects // Casts the given data value as a bitmapdata object.// 将一个图片class转化成一个bitmapdatashadeMaterial = new BitmapMaterial(Cast.bitmap(Shade));// Casts the given data value as a material object.// 将一个图片class转化成一个material对象materialArray = [Cast.material(GreenPaint), Cast.material(RedPaint)];
