PV3D虽然没有直接定义接口，但是在org.papervision3d.core.proto包里定义的已Object3D结尾的类，有几个属于顶级基类，其他的类都派生于此。
1。PV3D核心类如下：
1.1 显示对象容器类:
DisplayObjectContainer3D直接继承自flash内部的EventDispatcher类，支持事件派发。
1.2 材质对象类：
MaterialObject3D直接继承自flash内部的EventDispatcher类，支持事件派发。
1.3 场景对象类：
SceneObject3D继承自DisplayObjectContainer3D，是3维场景对象类。
CameraObject3D继承自DisplayObject3D，是摄像机对象类。
PV3D的DisplayObject3D是继承自DisplayObjectContainer3D的，这个容易和flash的内置继承层次混淆，flash内置的DisplayObject不是容器，而PV3D的DisplayObject3D是容器。
flash的内置继承层次是DisplayObjectContainer是继承自InteractiveObject –> DisplayObject，flash的DisplayObjectContainer是支持鼠标交互的。
而PV3D的Mesh3D是不直接支持和鼠标交互的，如果需要和鼠标交互，需要在传给场景构造的参数container上订阅鼠标事件。
2。PV3D在日志和缓动部分引用其他开源的包，如下：
com.blitzagency.xray.logger
caurina.transitions
