Speeding up QT images for web. What r sub tiles?
Posted: Wed Sep 26, 2007 8:44 am
Hi, I've copied the setting from the pano2 VR samples page for a basic cubic QT file (tilesize is 1201 pixels quality is 75, subtiles 3). And have created some of my own QT files and posted them. Two problems.
1. My posted file is VERY slow to load. Over 1 minute! File size is only 860kb. BUT the pano2 vr site's sample loads MUCH faster (and I've cleared my cache to make sure I'm doing the proper comparison). What am I doing wrong? If I reduce much more quality will suffer.
The image was created in PTGui (equirectangular, is a cylindrical view with significant cropping "limits."
2. My image does not get cached on Safari or Firefox, but the sample does! Why?
3. Also can someone explain what sub tiles are? I didn't follow this from the tutorial.
Thanks,
