Arrow flow animation in B4W

It's made with two modifiers Array and Curve. First modifier make multiple copies of a small piece of tube and shift it by one of the axis. Second modifier bend this geometry by simple spline curve. Look at this artile.

As always I have luck on my side, the tutoriallink is broken.. Shrinkwrap

And what do you mean exactly with "shift it by one of the axis"?

Just type in Google "Blender Encyclopedia: Modifiers" and second link will be the link that you need.

I mean that Array modifier not only just make a copy of the mesh but also shift it a little, look more closely on how the Array modifier works.

I'll keep trying. Thank you
