I believe that Andreas has updated a function that would help in this
regard called "tween", I think
Unaware of that, I built a rather complex animation tool. You can see a
temporary example at http://track.pacificcup.org/track.php?race=transpac
Select a boat from the left of the screen and then use the vcr controls
at the top to animate.
It works by maintaining an array of points that parallels the points in
the linestring. At selected intervals, I add a point from the array to
the linestring. Then I clear the linestring at the end.
To do fancier stuff, like go in reverse, I added a time attribute to
each point, so I can count backwards through the vertices (points) of
the linestring till I get to one that is older than the new cutoff time,
deleting the newer ones.
The code is, well, complex, because the page is doing a bunch of other
things. I keep meaning to extract an example, and perhaps I should!
Meantime, it IS possible.

Hi,
This page contains a broken ink to an animated polyine example (Line

Does anyone have a copy of this example? I would like to know if ti
would be possible to create an effect like this using openlayers:
http://econym.org.uk/gmap/example_cartrip2.htm (click start).
I actually don't need the map panning or to follow driving directions
as my use case requires a generic world map with the polylines linking
major cities. A closer example would be animated flight paths.
I would be extremely grateful if anyone could provide the missing
example or offer any advice on how to achieve this. I've been playing
with the cloudmade leaflet maps here:
http://jsfiddle.net/codecowboy/XkShV/22/ ( I want to animate the red
line - I will need to dynamically add lines to the map based on
lat/longs and distance covered by users)
Many thanks,
Luke Mackenzie
