我想通過使用osgGA :: AnimationPathManipulator將osg :: AnimationPath應用到我的osgViewer :: Viewer實例的攝像機。我的問題是,AnimationPathManipulator只適用於旋轉的變化,而不會改變相機的位置。所以它只能旋轉但不翻譯。OSG:使用AnimationPathManipulator進行攝像機飛行
我正在使用OpenSceneGraph庫3.0.1。
爲了更好的洞察力,這是我當前的代碼:
void CameraFlyTest::animateCamera(osgViewer::Viewer* viewer) {
osg::AnimationPath* path = new osg::AnimationPath();
path->setLoopMode(osg::AnimationPath::SWING);
osg::AnimationPath::ControlPoint cp1;
cp1.setPosition(osg::Vec3d(-200,-450,60));
cp1.setRotation(osg::Quat(M_PI_2, osg::Vec3(1,0,0)));
osg::AnimationPath::ControlPoint cp2;
cp2.setPosition(osg::Vec3d(2000,-500,60));
cp2.setRotation(osg::Quat(M_PI_4, osg::Vec3(1,0,0)));
path->insert(1.0f,cp1);
path->insert(3.0f,cp2);
osgGA::AnimationPathManipulator* apm = new osgGA::AnimationPathManipulator(path);
viewer->setCameraManipulator(apm);
}
