I am using a new approach now.. I am creating all of the tiles in offline mode and save it on disk, and then use those tiles in the runtime. The runtime performance became amazingly good... But the process of building tiles takes relatively long time. Although it is acceptable since it is done only once. but I think it could be dramatically reduced... The source code and discussion about it can be access here http://forum.worldwindcentral.com/showthread.php?t=16651&page=3 it is a multi-threaded queue based tile builder, it gave me the following results: total number of tiles: 760 tile size: 512x512 number of threads: 5 time: 1224203 ms (about 20 minute) total size of tiles: 38.2 MB I don't know it this is an acceptable timing... I looking for you suggestions and comments Please note: I am using gt-2.3.... gt-2.5 gave less performance for me... --- On Mon, 3/24/08, Jody Garnett <jod...@gm...> wrote: From: Jody Garnett <jod...@gm...> Subject: Re: [Geotools-gt2-users] WWJ integration To: "Ahmad Al-Obaidy" <ah...@wa...> Cc: geo...@li... Date: Monday, March 24, 2008, 12:32 AM I wrote the geotools tile module; it makes the WW servers available as a series a Colleciton<GridCoverage> which can be used with the streaming renderer. I implemented a queue for requests and a really simple in memory cache; you can see the results in my community module for uDig. > I working to integrate geotools with WWJ (open source Google earth written in Java) > > you can read about the integration in this thread > http://forum.worldwindcentral.com/showthread.php?t=16651 > > Currently, I am using StreamingRenderer, but I think I should switch to something else. > The renderer should be thread-safe and give performance advantages for subsequent paint calls. > > what is your recommendations? > > ------------------------------------------------------------------------ > > ------------------------------------------------------------------------- > This SF.net email is sponsored by: Microsoft > Defy all challenges.
