截圖：
參考對比下純D3D的實現：
《精通DirectX 3D》第十二章 高級紋理應用 06_SphericalEnvMapping
原理都是一樣的，都是有個環境貼圖，假的環境映射！
實現很簡單，override createScene成員函數就可以了
// Just override the mandatory create scene method
void createScene(void)
{
// Set ambient light
mSceneMgr->setAmbientLight(ColourValue(0.5, 0.5, 0.5));
// Create a point light
Light* l = mSceneMgr->createLight("MainLight");
// Accept default settings: point light, white diffuse, just set position
// NB I could attach the light to a SceneNode if I wanted it to move automatically with
// other objects, but I don't
l->setPosition(20,80,50);
Entity *ent = mSceneMgr->createEntity("head", "ogrehead.mesh");
// Set material loaded from Example.material
ent->setMaterialName("Examples/EnvMappedRustySteel");
// Add entity to the root scene node
mSceneMgr->getRootSceneNode()->createChildSceneNode()->attachObject(ent);
}
對應的材質腳本在
ogrenew\Samples\Media\materials\scripts\Example.material
里，如下：
material Examples/EnvMappedRustySteel
{
technique
{
pass
{
texture_unit
{
texture RustySteel.jpg
}
texture_unit
{
texture spheremap.png
colour_op_ex add src_texture src_current
colour_op_multipass_fallback one one
env_map spherical // hew:這里指明環境映射的類型是球形環境映射
}
}
}
}
