Awesome :) I tested on an iPhone 4 and on an "old" iPad. The 3d-accelerated version is a lot smoother on both. I've noticed that sometimes it lags for a bit just before you start panning, but I guess this is because the browser loads the tiles into memory or something. It also happens for the pinch-zoom trick I posted earlier. Despite the small delay, I still think the 3d-version is better. Also, I've tested pinch-zoom with translate3d on an iPad 2, and it's perfectly smooth with no delay at all :) So I guess the delay on some devices will slowly fade away as time passes.
This article has a bit more details about the effect of translate3d: http://www.html5rocks.com/tutorials/speed/html5/ Gregers On Fri, Apr 29, 2011 at 9:47 PM, Bart van den Eijnden <bart...@osgis.nl> wrote: > It's so much faster on my iphone4 that I sometimes get lost in the map! > > Great work Eric! > > Bart > > Sent from my iPhone > > On Apr 29, 2011, at 9:22 PM, Eric Lemoine <eric.lemo...@camptocamp.com> wrote: > >> Hi >> >> I've been experimenting using CSS3 translate3d transform for moving >> the layer container div when panning.
