How to add antialiasing to Polylines

[Coen de Jong]

My polylines on the map now look pretty ugly because the lines are not smoothened. Does anyone know how I can achieve that? Look at an example here: http://labs.shifthappens.nl/vagabond/pilot/

I can see smooth dashed curves in IE. Is your problem browser
dependent, or am I looking at the wrong thing?

Ditto Firefox 3.6.21. There's a kink in A-B, but the lines are rendered well.

Hmm. I just updated the website to show solid lines. That might clarify the issue a bit more. I agree that somehow, after a reset of my Chrome browser the lines do look better. It might also be the drawing algorithm that is flawed in this case.

Does anybody know a good way to draw arcs (curved lines) from point A to B on a google map?

Are you looking for geodesic lines?

or just curves:

Hi there! Yes actual curves, arcs from point to point. Geodesic lines only work on a very long distance, and I want to give the viewer the impression of a journey, with bows from destination to destination. Also for small distances.

Your 3rd example therefore seems very promising. I'll look into it to implement it into my own project. The lines look very detailed as well, much more than mine are now. Is it OK to return to this thread to ask you questions in case I get stuck?
