Tour too Slow

by fsimao222 » Sat Mar 22, 2014 11:18 am

Hi,
I'm new to virtual tours and hope someone can help me.
I've made one big virtual tour (21 (360x180) panoramas, 49 hotspots, 21 floor plan spots) with multi-resolution, incremental build, Flash and HTML5, JPG quality 12 and when I upload it to my server to see it online it is too slow to open and to change between panoramas, you even can see it rendering the panorama slowly.
I should be doing something wrong.

My panoramas size are: 3840x1920px at 300pixels/inch

here is the virtual toul to you can see.

Thanks

It doesn't seem that slow to me - viewing with latest Firefox on Windows 7 Pro 64-bit - and my Net connection is typically less than 3Mbps.

You could try reducing the JPEG quality to 8, 9 or 10.

Having a Little planet intro always slows initial load I think.

Switching between scenes seems acceptable to me.

Your pano images are rather small if they really are 3840x1920px.

6k x 3k would normally be considered the minimum for reasonable detail I believe, unless you are only ever going to display the pano is a small window on web page.

Much too high. Use 8. I did it here: http://www.360impressions.de/Lichtturm (700MPx per pano).

Yes: too much data-size due to JPG12.

Very small pixel-size - minimizes view-quality. 300dpi is ONLY needed for offset-printig in magazines and so.
Set your APG rendering to 72dpi (default) and set JPG to max. 8 in PTP.

best, Klaus

Regarding that more and more screens today have around 1920x1080px i suggest at least 10000 x 5ooopx for interactive panos being displayed in fairly good quality.

Sorry for the late reply.
Thanks for the help.
I'll test with lower quality, 72DPI and 10000x5000px.
Thanks again

question
if im exporting in autopano should i still export at max quality (12) then set it to 8 in panotour or can i use 8 for both? or will that reduce quality further since panotour would export a lower quality pano at at quality of 8?

I suggest to use TIFF for APG output and then 7 or 8 for JPG in PTP.
