如何把Papervision3d物体加到 flex中(附 立方体例子)

本文介绍怎么在flex项目中使用Pv3d。

需要你对flex有一定的了解。

方法1 直接在mxml文件中加入Pv3D组件

 

１。下载pv3组件，(Papervision3d 最新源代码和swc库文件：http://code.google.com/p/papervision3d/)

 

 

２。把Papervision3D_2.0.883.swc和header.swc加入工程。

 

３。源程序如下：

    xmlns:mx="http://www.adobe.com/2006/mxml"

    applicationComplete="applicationComplete()">

            bitmapMaterial.smooth=true;
            bitmapMaterial.interactive=true;
            var shader:Shader = new PhongShader(light, 0xffffff, 0x333333, 10, bitmap.bitmapData, bitmap.bitmapData);
            var shadedMaterial:ShadedMaterial = new ShadedMaterial(bitmapMaterial, shader);
           
            return shadedMaterial;
        }
       
       //滚动鼠标中间轮，进行缩放
       private function onWheels(event:MouseEvent):void
       {
               basicView.camera.moveForward(10*event.delta);
       }

        <mx:Label text="Label" id="testLabel"/>
    </mx:Panel>
</mx:Application>

 

４。运行效果如下：

 

 

 

方法２：使用自定义控件，把3d窗体封装到自定义控件中， 在主应用中引入这个自定义控件。

根据方法１进行自定义，源程序略。
