Ogre笔记（2）

创建平面：

Ogre::Plane plane(Vector3::UNIT_Y, -10);        // 通过法线创建一个平面
Ogre::MeshManager::getSingleton().createPlane("plane",
    ResourceGroupManager::DEFAULT_RESOURCE_GROUP_NAME, plane,
    1500,1500,20,20,true,1,5,5,Vector3::UNIT_Z);    // Vector3::UNIT_Z定义了面的正向


Ogre::Entity* ent = mSceneMgr->createEntity("LightPlaneEntity", "plane");
mSceneMgr->getRootSceneNode()->createChildSceneNode()->attachObject(ent);
ent->setMaterialName("Examples/BeachStones");    // 设定材质

点光源：

Ogre::Light* light1 = mSceneMgr->createLight("Light1");
light1->setType(Ogre::Light::LT_POINT);
light1->setPosition(0,20,0);
light1->setDiffuseColour(1.0f,1.0f,1.0f);

聚光源：

Ogre::Light* light = mSceneMgr->createLight("Light1");
light->setType(Ogre::Light::LT_SPOTLIGHT);
light->setDirection(Ogre::Vector3(1,-1,0));
light->setSpotlightInnerAngle(Ogre::Degree(5.0f));
light->setSpotlightOuterAngle(Ogre::Degree(45.0f));
light->setSpotlightFalloff(0.0f);
light->setDiffuseColour(Ogre::ColourValue(0.0f,1.0f,0.0f));
node2->attachObject(light);

方向光源：

Ogre::Light* light = mSceneMgr->createLight("Light1");
light->setType(Ogre::Light::LT_DIRECTIONAL);
light->setDirection(0,1,1);
light->setDiffuseColour(Ogre::ColourValue(1.0f,1.0f,0.0f));

设置阴影：

mSceneMgr->setShadowTechnique(SHADOWTYPE_STENCIL_ADDITIVE);

设置线框格式：

void createCamera()
{
    mCamera = mSceneMgr->createCamera("MyCamera1");
    mCamera->setPosition(0,100,200);
    mCamera->lookAt(0,0,0);
    mCamera->setPolygonMode(Ogre::PM_WIREFRAME);
}

设置镜头和视口：

void createCamera()
{
    mCamera = mSceneMgr->createCamera("MyCamera1");
    mCamera->setPosition(0,100,200);
    mCamera->lookAt(0,0,0);
    mCamera->setNearClipDistance(5);
}

void createViewports()
{
    Ogre::Viewport* vp = mWindow->addViewport(mCamera);
    vp->setBackgroundColour(ColourValue(0.0f,0.0f,1.0f));
    mCamera->setAspectRatio(Real(vp->getActualWidth()) / Real(vp->getActualHeight()));    
}
