不用BasicView 时：

package {
import flash.display.Sprite;// 在以后的程序中，我们将会让文档类继承pv3d内置的BasicView类。
import flash.events.Event;
import org.papervision3d.cameras.Camera3D;
import org.papervision3d.objects.primitives.Sphere;
import org.papervision3d.render.BasicRenderEngine;
import org.papervision3d.scenes.Scene3D;
import org.papervision3d.view.Viewport3D;
public class FirstApplication extends Sprite {
  private var scene:Scene3D;
  private var viewport:Viewport3D;
  private var camera:Camera3D;
  private var renderEngine:BasicRenderEngine;
  private var sphere:Sphere;
  public function FirstApplication() {
   stage.frameRate=40;//在pv3d 帧频要设置为40 ，这为最佳！此句一般放在构造函数的第一句
   scene = new Scene3D();
   camera = new Camera3D();
   sphere = new Sphere();
   scene.addChild(sphere);
   viewport = new Viewport3D();
   addChild(viewport);
   renderEngine = new BasicRenderEngine();
   this.addEventListener(Event.ENTER_FRAME,handleEnterFrame);

  }
  private function handleEnterFrame(e:Event):void {
   sphere.localRotationY+=2;
   sphere.localRotationX+=2;
   sphere.localRotationZ+=2;//实现旋转
   renderEngine.renderScene(scene,camera,viewport);//其作为渲染用，只执行一次！故放在enterFrame事件中。
  }
}
}

使用BasicView <可以把下面的代码当做模板使用，简洁代码> ：

package {
import flash.events.Event;
import org.papervision3d.objects.primitives.Sphere;
import org.papervision3d.view.BasicView;
public class BasicViewExample extends BasicView {
  private var sphere:Sphere;
  public function BasicViewExample() {
   /* super.BasicView(width=640,height=480,scaleToStage(是否让viewPort3D视窗为舞台大小));
                当想改变大小时可以用它

*/
            /*
    * @ author :夜梦惊魂
    */
   stage.frameRate=40;
   //下面只需定义3D对象，在将其add到scene中
   sphere = new Sphere();
   scene.addChild(sphere);
   startRendering();//创建secne3D basicRenderEngine viewPort3D camera3D
  }
  // 重写 onRenderTick 及其调用父类onRenderTick ;
  override protected function onRenderTick(e:Event=null):void {
   sphere.localRotationY+=1;//旋转轴
   super.onRenderTick();//开始渲染
  }
}
}
