Hi there,
have been playing a bit with the demo under http://novosibpano.ru/VT/sc/ and I think there might be a problem.
If you hide the bottom menu by clicking the hide button (2nd from the right)
or
disable the thumbnail preview (2nd button from the left)
then change the grouping category via the grouping menu (top left on screen) the thumbnail bar (at the bottom) will come up empty until you close/open it manually.
Hope I explained it in a way that it makes sense
Windows 10 and Chrome
I have put up an example of my version of a panoramic object VR
What does that mean ?
It is 32 full panoramic images layered and depending on where you look you will get to see the new panorama layer - a bit like a rotation controlled 360 timelapse.
You can choose different projections and pan around - this results in quite nice effects for little planet view.
Let me know what you think.
If there is any interest in the xml and/or the batch file to create the different layers I will post them.
The example can be seen under http://pano-timelapse.created-by.me/
Cheers,
Bernd
Yes, I think you are right - it really is more object VR than panorama.
Only "problem" will be that for full-screen and looking up/down I need the front/up/down cube face in decent quality which makes the image size (in terms of data) quite big.
Well hey - I might as well give it a go.
Thanks for the pointers.
Cheers,
Bernd
Your tour is blending 2 panoramas by really loading them - right . So you load a second panorama.
Sorry if my example doesn't really show what I would like to achieve and I know now that I picked the wrong images/panoramas.
My idea was to sort of do what panomoments ( https://www.panomoments.com/ ) does or what photosynth did.
So the images should be about 180 degrees vertical but only about 90 degrees wide. Taken in a rotating motion (not necessarily around to nodal point) you just convert those images to cubefaces which have a front, top and bottom - no stitching them together. Then you upload those cubefaces and the script positions them next to each other and when you "move" the panorama it will visualise movement.
Sorry for choosing such a bad example - will try to post something which shows better what I mean next week.
The problems with loading a new panorama would be that the old one is gone so if you go back and forth you would always need to reload (even though most will come out of cache this is not what I wanted).
That is why I used distorted hotspots because they allow me to have them all loaded and manipulate the alpha value or zorder. The idea with alpha value was that I could have a small blend phase not the hard cut only.
What I can't understand is why there is the stutter even though all the data is there ( I checked the network log of the chrome developer tools - all images are loaded to hotspots in the beginning) ?
Why would changing the alpha value affect the movement that much - but only the first time?
As I said - I will try to come up with a better example next week.
And thanks for the multires/preview image idea - will look into it.
Cheers
OK - I will give it one more go before the weekend
First try (first xml posted) setting hotspot alpha - stutters when going over the 90,180... boundaries when a new hotspot becomes visible - http://pano.5gbfree.com/cubeswitch/cubeswitch.html
Second try (second xml) using zorder to make hotspots visible -
tried to improve scripting - only do something if there is a change .....
works on panning without stutter but on first load - or in developer mode with empty cache and hard reload - the images overlap on loading.
Thought I set the zorder but perhaps not - http://pano.5gbfree.com/cubeswitchzord…itchzorder.html
Hope it works on that server for you.
I can certainly understand that you would need to see it and I have to say - I am confused. 
000webhostapp.com is a free hosting service based on hostinger.
I use it mainly for WebGL stuff and I have shared links to the site before with people.
Had the account for a couple of years now but only used it to share small projects.
I tried to reach the site via the tor browser and choose a couple of different countries to connect to the internet from and the site was always found.
Just asked some friends in Germany and it works there.
Well - but all that doesn't help if you can't see it.
I do not have my own domain/server so I need to sort that one out first - even though I'm not sure what to do about it.
Could post a screen video but that is just not the same as actually trying it.
Just a couple of things - pretty sure no HW problem NVidia 970 and as I said - no matter how small the tiles it always happens.
krpano version krpano 1.19-pr8 and I am forcing html5:only - works on my phone as well.
Will update the issue once I think I sorted out the 
hosting problem 
Thanks for trying anyway.
OK, tried several things.
Changes the script so only when actually going over a "border" and action will be called - no better.
Used visible instead of changing alpha value - no better.
Used zorder - and it works - panning without a stutter BUT when loading the images at the beginning it seems the zorder is not used?? The images come up one after another and then the one with the highest zorder comes to the top again. Changed order there or tried to make them visible afterwards but that didn't change anything.
In Chrome with developer tools switched on it makes a big difference if I do a "Empty Cache and Hard Reload" - doing that it properly cycles through all images (which is not nice).
So all in all - alpha change or visible change cause a "performance" hit which makes the panning stutter but just changing zorder does not???
But why then does it work OK with visible and alpha change when you panned around 360 degrees once?? Is it then all cached which speeds things up ??
I am still at a loss.
Put the second example also up - hope it works - cubeswitchzorder <-- loading "problem" cycles through images but panning all the way around is smooth with image change
The first example is still out - cubeswitch <-- problem there is that once you try panning past 90,180,270,0 it stutters the first time round - second time round everything is fine.
xml of cubeswitchzorder is attached
All my tries of using alpha, visible or force visibility are in but commented out.
Has anybody an idea why alpha/visible would create the stutter??
And - I don't mind going down the zorder route but how do I prevent the images from cycling trough at the beginning.
The idea is to have 16 or 32 images - not fully equirectangular but only "slices" (180 degrees vertical and perhaps 30 degrees wide) so any cycling through all whilst loading is not wanted - neither the stutter.
Again - any ideas welcome.
Cheers.

</krpano>Hmm, strange - it is for me.
Yes, they are not the most reliable and the occasional tile doesn't load but generally it should be fine. Just clicked it and it worked in Chrome and Edge.
It is not fast - so it might have the black window with "krpano Demo" for about 3 seconds before it loads the tiles.
Hope it works
Hi,
I am trying to use krpano to do something to PanoMoments or Photosynth.
I am loading (in this example/ configurable) 4 panoramas as cube faces and depending on panning (where you look) it switches every 90 degrees (360/4) from one panorama to the next.
Everything is working fine - all the cube faces are loaded on startup and I can drag the pano with the mouse
So far so good
BUT
The first time one of the 90 degree pans is reached there is a delay when it switches to the other panorama - ONLY THE FIRST TIME.
I checked with the network monitor but there is no loading happening.
Tried to figure it out with the performance monitor in Chrome and that shows that the first time there is a spike in "painting"
Once all the borders have been "painted" once it is all smooth but not the first time round.
As I said - the example is only 4 panoramas but I wanted to use it with 16/32 and then the stutter the first time round makes it quite unusable 
I have tried smaller tiles but it doesn't make a difference (smallest I tried was 512x512 and it still had this delay).
Anybody any idea?
You can see the example here under https://playingwithstuff.000webhostapp.com/cubeswitch/cubeswitch.html
The 4 images are the same pano just getting darker - so if you look around at 90 degrees the first time it will "hang" - from then on there is no problem.
I have attached the XML - perhaps I am doing something silly ??
Any ideas are appreciated.
Cheers.

so you might have solved that issue already 
Well the toursler tour is 36 panoramas which should I guess be more streetview style - like I can stand in one of the rows on the left, in the middle or on the right.
Yes, it is nice but- and that is just my opinion - I think it is over the top.
You don't spend much time looking at one panorama because there are so many of them.
So far I heard that the feedback of the tour is quite OK and it is live on
http://www.oum.ox.ac.uk/tour/tour.html
That looks quite nice.
I guess the problem is that the gyroscope with the browser is a bit - well - not so smooth.
It looks a bit like the Orbulus android app in terms of selection process and so on but it work on the web browser.
Full screen would be nice but there is this 'needs to be initiated by touch' problem.
Overall - really nice.
Thanks for the feedback!!
I have 'delivered' the tour last Wednesday so not much I can do about it any more.
Making the map inactive when small - yes, should have done that.
i button inconsistent - I know, should have created a new icon set instead of just adding something -
Nadir - well hey, don't have a Nadir adapter and HDR in fairly dark environment isn't going to work properly handheld.
Info screen fixed size - I tried resizeable but when the screen get small you can't read it any more so I decided to just keep it fixed.
I could not find the unnatural distortions.
Again thanks you for the detailed feedback.
It was/is a freebie for the museum and I know I should probably have spent more time with the krpano settings but for them it really is all about the images and the feedback there si far is that they like it.
I will try to be more consistent next time round.
Cheers.
Thanks for - well - literally nothing.
I mean - I know it is a bulk standard tour, nothing special so I guess no comment means nothing is really wrong with it - that is the way I take the silence.
So thanks for that.
I know, there are things with the images and the xml that could be improved and I will be working on it on my next tour but so far I take the absence of negative comments as a positive thing.
After all - I am not a glass half full or glass half empty person - I am just a person for whom the glass is double the size it needs to be. 
Cheers,
Bernd
This is my first 'proper' virtual tour which might actually end up on somebodies web site .
Any feedback is appreciated.
At the moment the tour is hosted on my google drive which is not the fastest so loading times should improve when the tour is moved to its proper home.
I tested it with Firefox, Chrome, Safari and IE11 as well as smartphone Chrome.
Things seem to be working OK.
Only IE11 never seems to show the intro image but that could be down to loading time
Cheers, Bernd
Wow - absolutely amazing.
Work like that shows that interactive panoramas can be more than just big images.
And thinking about the amount of work that went into that project - respect !!
