Ok, I've looked at Stefan's killer bear lines. 8^) (Those grizz sure get around...) I see the very slow performance in OJ. I also tried this in the JTS Test Builder app, which *doesn't* do an intersection() to clip the geometries to the viewport. The rendering is lightning fast using this

@white space when zooming out: Maybe you can use the drawing algorithm that draw the geometries like a pencil sketch when zooming with the slidebar (and then rerender the geometries at a given time interval). Screenshot: http://www.imagebanana.com/img/91inbax/pencil_sketch.jpg --Benjamin

So one thoughts is that maybe there's no point in clipping linear features? I think Swing is pretty good at rendering lines and clipping them by itself. Nice work Martin! I just couldn't bear (8^) the the thought of slow linestring rendering, so I added (and committed) a check for linear

Great! I dunno why we (ahem - Jon) didn't notice this way back when we first wrote this code. Always easier not to check for special cases, I guess... 8^) I'm betting this should be faster across the board for linear features. The intersection() method is very slow (for use in situations
