here is another example with animation and OpenLayers http://gis.ibbeck.de/ginfo/apps/Pentominoes/pentominoes.html click 'starten' or 'start' to begin the animation. Arnd Wippermann

I've got a little project that requires an "eye-catching" display of flow through a network of gas pipelines. I'm using MapServer 5.0.3 (with AGG) on Fedora Core 9 and I want to stick with open source technology if possible. Are there any examples out there of MapServer showing animation effects along a linear feature (i.e. road, river, pipeline, information flowlines, etc.) that I could look at to get some ideas? The first thought I had was to move colored dots along a pipeline in the direction of flow and use a timer to pace the animation. Each dot would represent the day's load from a source and they would move based on pipe diameter, pressure and other parameters that affect flow. This works, but the down side is that eventually you have a lot of objects to juggle and performance goes to heck. Then I thought of using a series of textures for each pipeline segment and swapping them iteratively to simulate an animating. What won't work is rendering the entire map image each time; that would go from eye-catching to mind-numbing pretty fast. So is there a way with MapServer to display a map base, but allow for objects to be "floated" on top in such away that I don't have to re-render the the entire map each time? (like an AJAX tool for mapserver?) If anyone has any ideas or knows of examples they could point me to, I'd appreciate it. - Bill Thoen
