Time for action—managing animation channels

To achieve the same animation effect that the animation path example has already done, we have to create two channels, one with a position animation target and the other with a rotation one.

The createAnimationPath() function, which generates a circular path around the origin point, can be reused. But instead of just combining the position and rotation values into a control point structure, these two kinds of key frames should be added to separate containers that belong to different animation channels.

1. Include the necessary headers:

   #include <osg/MatrixTransform> #include <osgAnimation/BasicAnimationManager> #include <osgAnimation/UpdateMatrixTransform> #include <osgAnimation/StackedTranslateElement> #include ...
