Ogre场景管理器：
分块地形和四叉树场景管理
Ogre默认没有提供四叉树场景管理器？
提供了class _OgreOctreePluginExport OctreeSceneManager : public SceneManager
// Initializes the manager to the given box and depth.
init();
// Cascade down the graph updating transforms & world bounds
// In this implementation, just update from the root
// Smarter SceneManager subclasses may choose to update only
// certain scene graph branches
updateSceneGraph();
/** Walks through the octree, adding any visible objects to the render queue.
@remarks
If any octant in the octree if completely within the view frustum,
all subchildren are automatically added with no visibility tests.
*/

// 创建一个Entity，定义物体的形状（3D网格）、是否可见等
Entity *ent2 = mSceneMgr->createEntity( "Robot2", "robot.mesh" );
// 创建一个Node（这个Node挂在Root Node下，偏离了根SceneNode50个单位），定义物体的方向、坐标、变换、旋转等
SceneNode *node2 = mSceneMgr->getRootSceneNode()->createChildSceneNode( "RobotNode2", Vector3( 50, 0, 0 ) );
// 将Entity挂载到Node上
node2->attachObject( ent2 );
