I think it is important to think about the future, for me it is important to offer products (VT) that function longer then 6 months, without the client having to pay extra for updates/upgrades.
1: about Flash, I personally like Flash very much no doubt about that. But as an internet consulter the theme is for some time now already, do not use flash (this is not my idea).
And this despite the fact that there is no standard multi-browser compliant alternative. That's why that 'do not ever use Flash' idea is so foolish at this time. I think perhaps people were perhaps overly influenced by the anti-Flash crusade of the late megalomaniac Steve Jobs.
So websites, shops, portals, videos, etc, made the switch to html5 and CSS3 or are thinking about doing this, this is the standard, (un)fortunatly.
That's obviously nonsense because HTML5 is not yet formal standard - so it cannot be 'the standard' can it? I'm not saying it won't be. I'm saying it cannot be yet.
I don't know about you but I still see lots of major sites using Flash.
2. Mobiles & Tablets: about 15% in different categories and business are using a mobile (tablet) today to visit a company website, shop, etc, say iPhone/iPad: 55% - Android 35% - rest 5%, (these figures are in general and my experience) these figures will be rising of course for the future
3. For many years already in companies networks, flash is not installed and/or blokked because of security reasons, also here the numbers are rising (my experience today: 30%). How do you want to sell this to the manager to invest in a product that is based mainly on Flash, how do you imagine to do a professional prasentation of your VT?
Well you can't tell him you can provide an HTML5-compliant tour because there's no HTML5 standard to comply with.
As far as I know at present there's no single alternative to Flash that you can guarantee will work on any system - desktop, laptop, tablet, or phone regardless of harware, browser and operating sytem. Probably at present the best you can offer as a Flash alternative is to support various specific combinations of hardware, browser and operating system. Are the managers you sell to smart enough to understand the subtleties of that idea?
4. Adobe is no longer supporting Flash for mobiles anymore (35% of the mobile users today (Android) will not be able to see the panoramas in Flash anymore, very soon)...what is next?
I'd suggest non-Flash Android-compatible alternatives. Will you be able to guarantee that stuff will work on any Android system? I don't expect so. There is too much variation betwen Android-based platforms unlike the rigid control Apple is able to exert over the hardware and software of iOS products.
My point of view these are important facts one has to know if you want to do a serious (longtime) business. The main thing is not about extra possibilities which funktion in 1 version but in the other version not the same.
The main issue is Flash/non Flash...and I really hope PTP2 comes with a good possibility, can not wait...
krpano already has the capbility to deliver different tour versions to different platforms - the challenge right now as I understand it is to be able to detect and identify the precise capabilities of the viewing platform (hardware and software) so as to be able to load the appropriate version.
I believe that krpano was the first to offer a Panorama Viewer for i-Devices and I see no reason why krpano (and Kolor) won't continue to innovate and lead the field.
