I work on a fairly large object movie which I'd like to present in full detail. Input files are over 4000px wide so this will create over 1GB of data. I need to maintain this resolution on mobile devices so I will create a a few multi resolution outputs, etc.
Now I wonder how to maintain pleasant user experience vs initial loading time vs stability across platforms.
My biggest issue is the object being blurred while rotating. This is because player use low-res layer and as soon as you stop rotate it will load higher res. It has been asked in this thread and I understand how it works. It makes sense and it is logical all hi res layers couldn't be preloaded. However I would prefer if higher resolution would be loaded only when user zoom-in. So in that case we could maintain same resolution for rotating and viewing but higher res would be loaded if user hit zoom-in button.
I was thinking to have default layer cache at start up and maybe only one hi-res layer for zoom. Also have a few different outputs for various screen resolutions. So for example for users with 1200x900 screen res, there will be two multires layers, one 1024px loaded at the start up and another full res 4000px. For people with old mobile phones there will be 600px layer cache at start up and then perhaps another two layers (1600px and 4000px).
What I would like to achieve is to load low res (cache at start up) first without loading hi-res until user hit zoom-in button. Is there any way to control when multires layers are loaded? If not, is there a way to find out how it works in the player, I mean how exactly different layers are loaded and when?
I hope my description is understandable
Many thanks
Kind regards
