从OGRE纹理到CEGUI纹理 —— 使用RTT实现3D角色预览

//创建嵌入CEGUI组建中的画中画

TexturePtr rttTex = TextureManager::getSingleton().createManual("RttTex", ResourceGroupManager::DEFAULT_RESOURCE_GROUP_NAME, TEX_TYPE_2D, 512, 512, 1, 0, PF_R8G8B8, TU_RENDERTARGET);
{
Camera* rttCam = mSceneMgr->getCamera("pictureCerame");

Viewport *v = rttTex->getBuffer()->getRenderTarget()->addViewport( rttCam );
v->setOverlaysEnabled(false);
v->setClearEveryFrame( true );
v->setBackgroundColour( ColourValue::Black );
}

CEGUI::Texture* rttTexture = mGUIRender->createTexture(rttTex);

CEGUI::Imageset* rttImageSet = CEGUI::ImagesetManager::getSingleton().createImageset("RttImageset", rttTexture);

rttImageSet->defineImage("RttImage", CEGUI::Point(0.0f, 0.0f),
CEGUI::Size(rttTexture->getWidth(), rttTexture->getHeight()),CEGUI::Point(0.0f,0.0f));

CEGUI::Window* sheet = CEGUI::WindowManager::getSingleton().createWindow( "DefaultWindow", "root" );
mGUISystem->setGUISheet(sheet);

CEGUI::Window* fWnd = (CEGUI::FrameWindow*)CEGUI::WindowManager::getSingleton().createWindow( "TaharezLook/StaticImage", "testWindow" );

fWnd->setProperty("Image", CEGUI::PropertyHelper::imageToString(&rttImageSet->getImage((CEGUI::utf8*)"RttImage")));
