I've made something similar, but without openlayers, so: no overlays, and no baselayer either... but it does the trick, this is how i've done it:
i grab the current extent, and the parameters of the current layer (luckilly i have only one...), and i build my own wms - getmaprequest. Then i've created an imagepreloader, that (surprise surprise) preloades all my images, and stores them in the memory of the browser. When they're all loaded, i loop over them (setinterval), and that's it, i have my animation!! grtz, Wouter Schaubroeck Geo Solutions www.geosolutions.be On Wed, Jun 18, 2008 at 2:53 PM, alinux <[EMAIL PROTECTED]> wrote: > > > Barend Kobben <[EMAIL PROTECTED]> writes: > >> >> HI, >> >> We actually have an MSc student just started on seeing how to do this using >> WMS-T and SVG.
