In this animation I use a red rectangle that is moving along a line. The way how the animation was created is exactly the same as in first two examples.
The anim02.*.jvx files created by utility xvc2jvx were used as keyframes for JavaView animation. JavaView applet uses default parameters with
<param name=Animation.firstKey value=1>
<param name=Animation.lastKey value=21>
<param name="Animation.framesPerSecond" value=12>
