osg2.99 版本中"euler"运动怎么实现？2.99版本examples中的osganimationsolid程序中有平移和旋转的代码（绿色部分），但编译出来的exe中只有平移功能，没有旋转功能。

以下是osganimationsolid.cpp中的部分程序代码：


osg::ref_ptr<osg::MatrixTransform> trans = new osg::MatrixTransform();

trans->setName("AnimatedNode");

trans->setDataVariance(osg::Object:YNAMIC);

osgAnimation::UpdateMatrixTransform* updatecb = new osgAnimation::UpdateMatrixTransform("AnimatedCallback");

updatecb->getStackedTransforms().push_back(new osgAnimation::StackedTranslateElement("position"));

trans->setUpdateCallback(updatecb);
    trans->setMatrix(osg::Matrix::identity());
    trans->addChild (geode.get());

    root->addChild (axe.get());
    root->addChild (trans.get());

    // Define a scheduler for our animations
    osg::Group* grp = new osg::Group;
    osgAnimation::BasicAnimationManager* mng = new osgAnimation::BasicAnimationManager();
    grp->setUpdateCallback(mng);

    grp->addChild(root);

    // And we finaly define our channel
    osgAnimation::Vec3LinearChannel* channelAnimation1 = new osgAnimation::Vec3LinearChannel;
    channelAnimation1->setTargetName("AnimatedCallback");
    channelAnimation1->setName("position");
    channelAnimation1->getOrCreateSampler()->getOrCreateKeyframeContainer()->push_back(osgAnimation::Vec3Keyframe(0, osg::Vec3(0,0,0)));
    channelAnimation1->getOrCreateSampler()->getOrCreateKeyframeContainer()->push_back(osgAnimation::Vec3Keyframe(2, osg::Vec3(1,1,0)));
    osgAnimation::Animation* anim1 = new osgAnimation::Animation;
    anim1->addChannel(channelAnimation1);
    anim1->setPlayMode(osgAnimation::Animation:PONG);


    osgAnimation::Vec3LinearChannel* channelAnimation2 = new osgAnimation::Vec3LinearChannel;
    channelAnimation2->setTargetName("AnimatedCallback");
    channelAnimation2->setName("euler");
    channelAnimation2->getOrCreateSampler()->getOrCreateKeyframeContainer()->push_back(osgAnimation::Vec3Keyframe(0, osg::Vec3(0,0,0)));
    channelAnimation2->getOrCreateSampler()->getOrCreateKeyframeContainer()->push_back(osgAnimation::Vec3Keyframe(1.5, osg::Vec3(2*osg::PI,0,0)));
    osgAnimation::Animation* anim2 = new osgAnimation::Animation;
    anim2->addChannel(channelAnimation2);

求助！osg2.99中怎么实现旋转功能？
    anim2->setPlayMode(osgAnimation::Animation:OOP);

array

就是osganimationsolid例子，它很明显地同时实现了平移和旋转
