Hi,
It may be a simple one, but I am struggling since two days. I am using a osg::Switch to load multiple models. It loads OSG models for some options time and videos for some options. When I loaded models the model displayed in the middle of the screen. If I display the video it is not in the scope of the screen. I took transformation matrix and did some rotations and transilations but i am unable to place the video at the center of the screen. can any one help me how to bring the video to the center of the screen. My Viewer Settings Code: viewer = new osgViewer::Viewer(); viewer->setUpViewInWindow (200, 200, videoXRes, videoYRes); viewer->getCamera()->setViewport(0,0,videoXRes,videoYRes); viewer->setLightingMode(osg::View::HEADLIGHT); viewer->addEventHandler(new CSimpleWndSizeHandler(videoXRes,videoYRes)); /*p is projection matrix from camera*/ viewer->getCamera()->setProjectionMatrix(osg::Matrix(p)); When I switch from model to video my code is as follwos Code: modelSwitch->setAllChildrenOff(); modelSwitch->setChildValue(videoTransMat,1); /*Here i am doing some rotationa and transform operations on "videoTransMAt". but i am unable to center to it*/ As in the OsgMovie example i created a 2d Texture and playing movie. It is as follows Code: img = osgDB::readImageFile(filename); videoStrm = dynamic_cast<osg::ImageStream*>(img); videoStrm->setLoopingMode(osg::ImageStream::LoopingMode::LOOPING); mVideoTexture = new osg::Texture2D; geode = new osg::Geode; mVideoTexture->setImage(videoStrm.get() ); geode->addDrawable(osg::createTexturedQuadGeometry( osg::Vec3(0, 0, 0), osg::Vec3(videoWidth, 0, 0), osg::Vec3(0, 0, videoHeight) )); geode->getOrCreateStateSet()->setTextureAttributeAndModes(0, mVideoTexture, osg::StateAttribute::ON ); videoTransMat = new osg::MatrixTransform(); videoTransMat->addChild(geode.get()); modelSwitch->addChild(videoTransMat); ... I am getting error when the video reaches to the end. My video is not in loop. But I set looping mode to osg::ImageStream::LoopingMode::LOOPING Can you please help me how to play the video in the center of the screen and set the video in loop. Thank you!
