示例1: clear
void rtt::clear(unsigned buffers, const colour &c, float d, unsigned s)
{
assert(_viewport);
Ogre::RenderSystem *rs = Ogre::Root::getSingleton().getRenderSystem();
rs->_setViewport(_viewport);
rs->clearFrameBuffer(buffers, c, d, s);
}示例2: end
void OgreRTTexture::end()
{
Ogre::RenderSystem* system = Ogre::Root::getSingleton().getRenderSystem();
system->_setViewport(mSaveViewport);
#if OGRE_VERSION >= MYGUI_DEFINE_VERSION(1, 7, 0) && OGRE_NO_VIEWPORT_ORIENTATIONMODE == 0
Ogre::OrientationMode orient = mSaveViewport->getOrientationMode();
system->_setProjectionMatrix(Ogre::Matrix4::IDENTITY * Ogre::Quaternion(Ogre::Degree(orient * 90.f), Ogre::Vector3::UNIT_Z));
#else
system->_setProjectionMatrix(Ogre::Matrix4::IDENTITY);
#endif
}示例3: begin
void OgreRTTexture::begin()
{
Ogre::RenderTexture* rtt = mTexture->getBuffer()->getRenderTarget();
if (mViewport == nullptr)
{
mViewport = rtt->addViewport(nullptr);
mViewport->setClearEveryFrame(false);
