Hi Dennis!

Even with zooming the jaggies must not be seen. They must be interpolated in the browser´s engine in a very short time so they´re invisible running on a fast system.

Zooming always means scaling pixels. We need to differ pixels in the image-data from pixels displayed on the screen.
Scaling the screen is related to the pixel-pitch of the display and the rendering in the browser.

Zooming to more than 100% on a display and complaining about jaggies would be ridiculously amateurish.

So given there are no jaggies in the IMAGE - and there are none as you can see @100% - the quality of rendering while zooming depends on the quality of the system you´re displaying the panorama on.

I only can recall it over and over: NONE of our - high profile - clients ever complained about jaggies.
NONE of my - also high profile - professional collegues over here told me about seeing jaggies displaying my panoramas on their systems.

Be absolutely sure i would not show panoramas at all having such heavy kind of jaggies as we see them here from John and Burake - and as it seems ONLY from them.

wink cool

best, Klaus

PS:

again: the only explanation coming to my mind is whether Burak´s and John´s browsers for some reason take the html5/JS data instead of the Flash data.
HTML5/JS cannot display multiresolution - but a 700mpx pano of course can only work as it should using multiresolution.

A related article
en.wikipedia.org/wiki/Mipmap

Also bare in mind that some graphic cards and maybe some displays have their own antialiasing filter available or ON by default.

Thanks to everyone for the input here. Meanwhile I've tested my tour on different devices (1 desktop and 1 laptop) with different browsers and all show these jaggies. This is not about your tour Klaus, I tested my own tours that I create in PTP. My own computer and the other two devices are all quite expensive with a relative good standard. Relative to other devices that the viewers in my country will use. This is merely a problem of mine; I am not interested in an endless discussion, but I am having the problem at least here on the test devices. I don't think the normal viewer will ever notice it either, but as I said I don't have it in pano 2VR. No I am not affliated with pano2VR smile and nor do I have a 700 MP tour and not planning to shoot one in near future smile It isn't about the 700 mp tours it is about what I create (10000x5000 panos) with PTP 1.8 and sell to my customers.
Regards
Burak

Hey Burak!

" I am not interested in an endless discussion, but I am having the problem at least here on the test devices."

Nor am i.

But i take such an issue seriously. That´s why i´m looking for a reason why it happens at you and John´s hardware alone.

Meanwhile i sent his thread to some professional collegues here and in the US.

Not a single one of them has these jaggies in my tour. Not in THIS tour and not in other panos or tours i made with PTP.
And i also can´t see any jaggies in THEIR panos and tours which THEY make using PTP.

So - as long the jaggies appear only with you and John it doesn´t really move me . . wink

Makes me simply wonder in technical terms where you and John get them from . . .

best, Klaus

Hey Klaus,
Will you be so kind and check this tour of mine (just the first panorama)?. I had already posted the jaggies I see here in my screenshot. One has to move a little in the direction "left" from the opening position (no zooming-in, just the deafult FOV! )

Thanks in advance and best regards

Hi Burak!

Under some angles there are minor jaggies on the blue window frames.
That´s quite normal especially for low-res panos.
There´s some "smearing" in the structures on the ceiling - which looks like noise-reducing the shots.

best, Klaus
