Loading Times and that black screen

I would like to compare load speeds and discuss how we can change things in the xml or the html file to make krpano load faster and how to kill that black screen on load

Here are 3 examples with 3 differant flash players

not completely on topic but here is a list of all pano players for comparison.

Here is the start of some load time testing.

I wish we could prioritize loadin ourselves somewhy besides preload=true it would be nice to assign values to plugins and hotspots that would allow them to be loaded in the order we chose. the important ones could load first and the others later.

Hi,
so can anybody suggest how to speed up the visual load or have something to show loading on the black screen
the loading order is as follow:
- krpano.swf
- the xml
- the preview image / parallel to that it starts loading the plugins/hotspots
- after the preview image the pano image/tiles will starting

but when you get an black screen, then the loading of the html, swf and xml and the preview image already takes too long...

the following things could speed up the loading:
- optimize the filesizes (compression) of the images (as small as possible)
- optimize the tilesizes
- maybe try using cubes (will give faster and better rendering too)

- disable autorotation while loading:

Source code

1
2
<autorotatate enabled="false" ... />
<events onloadcomplte="set(autorotate.enabled,true);"/>


- use more parallel downloads, e.g.:

Source code

1
<network downloadqueues="6" decodequeues="2" />



I wish we could prioritize loadin ourselves somewhy besides preload=true it would be nice to assign values to plugins and hotspots that would allow them to be loaded in the order we chose. the important ones could load first and the others later.
partially that can be already done:
- in the kprotect tool by sorting the files
- or by dynamically adding plugins/hotspots (via. addplugin(), addhotspot() and maybe using delayedcall())
- let the url="" empty and set it 'later' (via some events or delayed calls) to start the loading

best regards,
Klaus

If you need to edit the tiles, you have a choice of these (and possibly more choices too).
-sphere to cube tiff.bat
-sphere to cube jpg.bat
-ktransform.exe (Michel wrote a good explaination to the use of this tool, just search the forum)

If you don't have to edit the cubes, you can use this just like you used kmakemultires.bat

-SPHERE to CUBE MULTIRES droplet.bat
