bone节点如何实现动画控制

yugang2010

大家帮忙看看下面这段代码，是哪里出了问题，里面的模型不能实现动画。

1. 
   
2. 
   
3. [code]int _tmain(int argc, _TCHAR* argv[])
   
4. {
   
5. osg::ref_ptr<osg::Group> root;
   
6. root= new osg::Group;
   
7. 
   
8. osg::ref_ptr<osgAnimation::Bone> bone =new osgAnimation::Bone;
   
9. bone->setMatrixInSkeletonSpace(osg::Matrix::translate(1.0,0.0,0.0));
   
10. bone->setName("bone");
    
11. bone->setDefaultUpdateCallback("bone");
    
12. 
    
13. osg::ref_ptr<osg::Box>box=new osg::Box((osg::Vec3(1.0,0.0,0.0))*0.5,1,0.2,0.2);
    
14. osg::ref_ptr<osg::Geode> geode=new osg::Geode;
    
15. geode->addDrawable(new osg::ShapeDrawable(box.get()));
    
16. bone->addChild(geode.get());
    
17. 
    
18. osg::ref_ptr<osgAnimation::Skeleton> skelroot= new osgAnimation::Skeleton();
    
19. root->addChild(skelroot.get());
    
20. skelroot->addChild(bone);
    
21. 
    
22. osgAnimation::Animation* anim = new osgAnimation::Animation;
    
23. anim->setPlayMode(osgAnimation::Animation::LOOP);
    
24. {
    
25. osgAnimation::QuatKeyframeContainer* keys0 = new osgAnimation::QuatKeyframeContainer;
    
26. osg::Quat rotate;
    
27. rotate.makeRotate(osg::PI_2, osg::Vec3(0,0,1));
    
28. keys0->push_back(osgAnimation::QuatKeyframe(0,osg::Quat(0,0,0,1)));
    
29. keys0->push_back(osgAnimation::QuatKeyframe(3,rotate));
    
30. keys0->push_back(osgAnimation::QuatKeyframe(6,rotate));
    
31. osgAnimation::QuatSphericalLinearSampler* sampler = new osgAnimation::QuatSphericalLinearSampler;
    
32. sampler->setKeyframeContainer(keys0);
    
33. osgAnimation::QuatSphericalLinearChannel* channel = new osgAnimation::QuatSphericalLinearChannel(sampler);
    
34. channel->setName("quaternion");
    
35. channel->setTargetName("bone");
    
36. anim->addChannel(channel);
    
37. };
    
38. osg::ref_ptr<osgAnimation::BasicAnimationManager>manager=new osgAnimation::BasicAnimationManager;
    
39. manager->registerAnimation(anim);
    
40. manager->buildTargetReference();
    
41. manager->playAnimation(anim);
    
42. root->setUpdateCallback(manager.get());
    
43. osgViewer::Viewer viewer;
    
44. viewer.setSceneData(root.get());
    
45. return viewer.run();
    
46. }

我没有细看，不过粗看的话，没有发现您使用StackedTransform和UpdateBone。请参看osganimationskeleton
