Using JPEG2000 won't work in this case. If you use one HUGE image for the whole world, then you have to download the whole image if you zoom in. If you lots of small images, then you have to download LOTS of images if you zoom out. Even if those become small when you zoom out, that would still be very inefficient (and slow) to do via HTTP. -- Carlo Wood <[email protected]> _______________________________________________ Policies and (un)subscribe information available here: http://wiki.secondlife.com/wiki/SLDev Please read the policies before posting to keep unmoderated posting privileges
