Qt에 OGRE 1.7을 통합

Question

Qt 4에서 Ogre 3d를 통합해야합니다. 불행히도 구식 인 몇 가지 코드와 제안을 발견했습니다. 나는이 튜토리얼

그것은 오우거 1.4.9 (Eihorn)와 함께 작동하지만 최근 버전 1.7.0로 좋아했다. 최근 앱으로 컴파일하면

이 문제의 원인은 무엇이며 어떻게 해결할 수 있습니까?

Answer 1

OgreBuildSettings.h의 메모리 할당자는 아마 Ogre가 실제로 빌드 된 메모리를 반영하지 않습니다. 당신이 오우거를 구축 (또는 #define OGRE_MEMORY_ALLOCATOR의 숫자와 함께 연주 할 때 사용되는로 변경합니다. 당신이 오우거를 업데이트하고 대안에 OgreBuildSettings.h을 대체하는 것을 잊지 (경로를 포함 어쩌면 프로젝트의).

Answer 2

QT4를 사용하는 예 때 발생 및 ogrewidget.cpp에서 오우거 Eihort http://www.ogre3d.org/tikiwiki/QtOgre

는 대체 ....

// setup a renderer 
    Ogre::RenderSystemList *renderers = mOgreRoot->getAvailableRenderers(); 
    assert(!renderers->empty()); // we need at least one renderer to do anything useful 

    Ogre::RenderSystem *renderSystem; 
    renderSystem = chooseRenderer(renderers); 

    assert(renderSystem); // user might pass back a null renderer, which would be bad! 

으로 ....

// setup a renderer 
    Ogre::RenderSystemList::const_iterator renderers = mOgreRoot->getAvailableRenderers().begin(); 
    while(renderers != mOgreRoot->getAvailableRenderers().end()) 
    { 
     Ogre::String rName = (*renderers)->getName(); 
     if (rName == "OpenGL Rendering Subsystem") 
      break; 
     renderers++; 
    } 

    Ogre::RenderSystem *renderSystem = *renderers; 

그리고 그것은 사용하기

오우거 1.7.3와 함께 작동 ...

OgreWidget * ogreWidget = 새로운 OgreWidget();
