這是使用蓋莫游戲引擎2.1.1做的簡(jiǎn)單球面映射
比較簡(jiǎn)單的不說(shuō)什么
獻(xiàn)上貼圖:
再上代碼
1 using namespace std;
2 using namespace core;

5 {
6 //! 初始化引擎設(shè)備并得到設(shè)備指針
7 RefPtr<Device> device = core::InitDevice("球面映射");
8 //! 得到引擎場(chǎng)景指針
9 RefPtr<SceneManager> scenemanager = device->GetSceneManager();
10 //! 得到引擎資源指針

16 //! 獲取引擎視頻驅(qū)動(dòng)器
17 RefPtr<VideoDriver> videodriver = device->GetVideoDriver();

26 background->Generate();
27 reflect->Generate();

題外話:截止目前引擎支持2d紋理,球面映射和立方體紋理
其它相關(guān)的映射和紋理會(huì)陸續(xù)加入
