Dear all,
I have a scene structure like this:
rootNode -> matrixTranformNode -> objectNode
I modify the position and orientation of the object by setting the
matrix of the matrixTranformNode and it works well. But the problem
appears when I try to use animation path. I create an animation path
like this:
osg::AnimationPath* animationPath = new osg::AnimationPath;
animationPath->setLoopMode(osg::AnimationPath::NO_LOOPING);
//initialize startPoint, endPoint, rotation
animationPath->insert(0.0,osg::AnimationPath::ControlPoint(startPoint
, rotation));
animationPath->insert(0.0,osg::AnimationPath::ControlPoint(endPoint
, rotation));
matrixTranformNode->setUpdateCallback(new
osg::AnimationPathCallback(animationPath));
The animation looks as expected. But after the animation I try to
update the matrix of matrixTranformNode, it doesn't work properly. The
object is still in the place of the last frame of animation, and it
won't change its position and orientation no matter how I try to
change the matrix. When I try to call getMatrix method of
matrixTransformNode, the matrix is changed as I set it. But the object
isn't displayed correctly.
Could any of you tell me what happens with the matrixTransformNode
after the animation? How can I manipulate the object again after the
animation?
Note that I did try to replace the matrixTransformNode by a new one
(so the scene structure is rootNode -> newMatrixTransformNode ->
objectNode), and then I could manipulate the object again. But this
doesn't work smoothly when you want to have continuous motion between
the animation created by AnimationPath and the animation created by
your manipulation.
Thanks,
Dat
