这里参照的是OgreWiki初级教程，用的是网上提供的 Ogre Wiki Tutorial Framework。用的cmake编译执行。
先看最终效果：
核心代码：
void TutorialApplication::createScene(void)
{
mSceneMgr->setAmbientLight(Ogre::ColourValue(1.0, 1.0, 1.0));
Ogre::Entity* ogreHead = mSceneMgr->createEntity("Head", "ogrehead.mesh");
Ogre::SceneNode* headNode = mSceneMgr->getRootSceneNode()->createChildSceneNode("HeadNode");
headNode->attachObject(ogreHead);
headNode->yaw( Ogre::Degree( -90 ) );
Ogre::Entity* ogreHead2 = mSceneMgr->createEntity( "Head2", "ogrehead.mesh" );
Ogre::SceneNode* headNode2 = mSceneMgr->getRootSceneNode()->createChildSceneNode( "HeadNode2", Ogre::Vector3( 100, 0, 0 ) );
headNode2->attachObject( ogreHead2 );
headNode2->pitch( Ogre::Degree( -90 ) );
headNode2->scale( 1, 2, 1 );
Ogre::Entity* ogreHead3 = mSceneMgr->createEntity( "Head3", "ogrehead.mesh" );
Ogre::SceneNode* headNode3 = mSceneMgr->getRootSceneNode()->createChildSceneNode( "HeadNode3", Ogre::Vector3( 200, 0, 0 ) );
headNode3->attachObject( ogreHead3 );
headNode3->roll( Ogre::Degree( -90 ) );
}
几个重要的概念：
1． SceneManager：所有屏幕上可见的东西都由SceneManager来管理；有多种类型的SceneManager，分别用来渲染Terrain、BSP等等。
2． Entity：初步的理解一个Entity代表一个Mesh（可以含有动画），Light，Camera，Particle，Billboard不用Entity表示。Entity不能直接加到场景中，必须先attach到一个SceneNode上，SceneNode管理位置和方向。
3． SceneNode：SceneNode管理位置和方向；需要注意子节点的是在父节点的空间中；一个SceneNode可以管理多个对象。
4． OGRE中的Entity和SceneNode都必须指定全局唯一的名称。
CMakeFiles.txt也需要一些改动:
