Fluidity in the display's functions ?

    Hi,

    I'm not really convinced by the fluidity and the comfort of vision when i "move" in my virtual-multires-tour (not from one to another, just in the current picture). I've got some kind of "skipped frames" when i move, even when i've done a complete turn.

    http://www.mitconseil.eu/FTPMIT/Public/…vtour/tour.html

    So i''ve created a "display" part in my xml and changed the settings (specially the move quality), no success. (Any display paragraph in the generated xml when editing on local ? Why ? there's one when xml's editing in the browser !)

    So i thought may be my pictures were too heavy ? 1.4 Go
    Then i've tried with lighter's panoramas and a different droplet, no changes either.!

    In those examples, when you move again on an area already seen, the fluidity is perfect. Does that mean the browser keeps the tiles, or whatever, in memory ? If so, do i have to change something in my config file, template or xml ?

    Hi,

    I think that what you mean with 'skipped frame' is this case:

    when the flashplayer has downloaded a image file (e.g. a jpeg),
    this image must be decode into its pixels,

    this decoding process is unfortunately not asynchronous, that means
    the whole flashplayer is blocked for a short time during that decoding,

    this is a limitation of the flashplayer itself,
    you can only control that effect a bit by the tilesize and the number
    of images to be decoded at the same time,

    e.g.
    try a decodequeues setting of 1:

    Code
    <network decodequeues="1" />

    and maybe a larger tilesize (change the tilesize setting in the .config file from auto to a higher value, e.g. 1000),
    the larger the tile the more screen space it covers and the viewer tiles must be decoded,

    best regards,
    Klaus

    Hi Klaus,

    Thanks for your time.
    I understand the specifity of multires (many tiles etc..). Indeed, i've tried with the "normal" droplet instead of the "multires" and with 6 tiles, it works really better. The movement is clean, no "jerks" (until cube size=3600, upon it begins to be too heavy).

    But in your example (also a multires) :

    https://krpano.com/krpano.html?pano=panos/owens/owens.xml

    once it loaded, wherever you move it's fluid ! How could i reproduce this ? Less tiles in your example ? Larger, as you said ?

    I try to change the .config settings and come back to you.

    Thanks. *g*

    these are the settings, klaus used in the example:

    <display details="22"/>
    <network downloadqueues="6" decodequeues="2"/>
    <image type="CUBE" multires="true" tilesize="1000">
    4 levels with 2 steps (8000-4000-2000-1000)

    alsoo decoding is performed by the cpu I think (maybe flash10 does with gpu) which means, if you have lots of actions or other stuff on your pc running, it can take some time.

    Hi Zephyr,

    Thanks for your answer.
    I'm gonna try it. Last days i tried to set a good "normal" virtual tour with hotspots textfield etc.. so i forget the "multires" for a few more days and then come back to let you know.

    I think my CPU and Gpu are ok. I've got an i5 and ATI Radeon HD 4800, saphyr i think. And i tried with nothing else running on my PC, doesn't change. I think it's a matter of settings..

    Thanks.
    Later. *g*
