Try JSTS. It integrates very well with OpenLayers and contains the
Buffer-function client side in javascript. That means it works on
features in a vector-layer. I'm not sure if that is what you're looking
for though.

Good luck!

Hi,
I need to implement a "simple" buffer tool. The tool should simply
place a Buffer zone around the position clicked in the map when the
tool is activated.
...the tool should work like this...
1. Activate tool in toolbar
2. Set Radius in map units
3. Click in map
4. buffer polygon based on the set radius is created and rendered in
the map
My system is Geoserver 2.1.2 / Postgis 1.5
I have done this with an sld and also in postgis ...but I really need
the real-time effect in the map!
any help or examples would be great,
yours,
Robert
