3.scaling

接下来就是形变。注意这里出现了一个创建子节点的新方法。这里只贴出createScene()。另外有一个setScale()，和scale()差不多。

void createScene()
{
Ogre::Entity* ent = mSceneMgr ->createEntity("MyEntity", "Sinbad.mesh");
Ogre::SceneNode* node = mSceneMgr ->createSceneNode("Node1");
node ->setPosition(10, 10, 0);
mSceneMgr ->getRootSceneNode() ->addChild(node);
node ->attachObject(ent);

Ogre::Entity* ent2 = mSceneMgr ->createEntity("MyEntity2", "Sinbad.mesh");
Ogre::SceneNode* node2 = node ->createChildSceneNode("Node2");
node2 ->setPosition(10, 0, 0);
node2 ->attachObject(ent2);
node2 ->scale(2.0f, 2.0f, 2.0f);

Ogre::Entity* ent3 = mSceneMgr ->createEntity("MyEntity3", "Sinbad.mesh");
Ogre::SceneNode* node3 = node ->createChildSceneNode("Node3", Ogre::Vector3(20, 0, 0));
node3 ->attachObject(ent3);
node3 ->scale(0.2f, 0.2f, 0.2f);
}
