Java3d：移动相机和动画

In my game I move the camera in my KeyBehavior (extends ViewPlatformBehavior) This works fine but I'd like to be able to move the camera in a more fluid way. Currently these moves are about 1 meter each and look like a "step". Any idea how to animate the camera move between the 2 vectors? In my game I move the camera in my KeyBehavior
