Hi, i think the right way to go would be to use grid strategy:
http://dev.openlayers.org/sandbox/vector-behavior/examples/strategy-grid.html Unfortunetely I think there should be some work done on it still (i dont know the current state of it, maybe somebody else knows more) http://openlayers.org/pipermail/dev/2009-February/004479.html Cheers On Thu, Nov 19, 2009 at 8:25 PM, Andreas Hocevar <ahoce...@opengeo.org> wrote: > Hey- > > what you want would require a redesign of how vector layers are drawn. > Right now, only the visible area is drawn.
