II.USE

1).創(chuàng)建與釋放

ET::TerrainManager* mTerrainMgr;
ET::SplattingManager* mSplatMgr;

mTerrainMgr = new ET::TerrainManager(mSceneMgr);
mSplatMgr = new ET::SplattingManager("ETSplatting", "ET", 128, 128, 3);

  delete mTerrainMgr;
  delete mSplatMgr;

2).設(shè)置相關(guān)細(xì)節(jié)

// create a fresh, mid-high terrain for editing
ET::TerrainInfo terrainInfo (129, 129, std::vector<float>(129*129, 0.5f));

// create a manual lightmap texture
TexturePtr lightmapTex = TextureManager::getSingleton().createManual( "ETLightmap", "ET", TEX_TYPE_2D, 128, 128, 1, PF_BYTE_RGB);

Image lightmap;
ET::createTerrainLightmap(terrainInfo, lightmap, 128, 128, Vector3(1, -1, 1), ColourValue::White,ColourValue(0.3, 0.3, 0.3));

// load the terrain material and assign it
MaterialPtr material (MaterialManager::getSingleton().getByName("ETTerrainMaterial"));
mTerrainMgr->setMaterial(material);

III.扯淡

地形的本質(zhì)是

class Tile : public Ogre::Renderable, public Ogre::MovableObject

TerrainImpl::createTerrain創(chuàng)建地形的時(shí)候，用設(shè)置信息創(chuàng)建tile:TerrainImpl::createTiles

node = mTerrainNode->createChildSceneNode(name);

mTiles[i][j] = new Tile(name, mSceneMgr, this, mIndexHandler, mInfo, mOpt, i*(mOpt.tileSize-1), j*(mOpt.tileSize-1));
node->attachObject(mTiles[i][j]);

mTerrainNode(OGRE::SceneNode型)是地形的根，命名規(guī)則是“mInstanceName + "/Terrain"” 當(dāng)然mTerrainNode的父節(jié)點(diǎn)是root。 tile合成了地形，玩啥就和tile玩吧。都整到這一部了，那該干嘛干嘛。

IV.淺嘗輒止

deform地形的時(shí)候，還是有些復(fù)雜處理的。貼圖的時(shí)候，也有處理的。還聽(tīng)人說(shuō)有裂縫一說(shuō)。還是有些技巧的。雖然沒(méi)有OGRE1.7.2新地形那么負(fù)責(zé)，ETM還是值得一玩的。
