iOS Flickering Pano

Hi
I have exported my Pano using KRPano 1.0.8.14 and I have full licences to use the iPhone/iPad plugin.

The problem is that my Panos flicker and jump around when viewed on the iPad and the iPhone (as well as in Safari on Mac when rendering as iOS)

Please go to http://www.bettondesignwork.co.uk/scarbo…sle01/pano.html to see what I mean.

Any help would be appreciated.

Thanks

Tuur

for mobile devices you better set vfov but that restriction also goes at the top.

*question*

better first do:
<view hlookat="100" vlookat="0" limitview="range" fovtype="MFOV" fov="90" hfov="360" vfov="120" maxpixelzoom="2.0" fovmin="60"
fovmax="120" vlookatmin="-60" vlookatmax="+60" />

or so..
just that.. and see..

http://www.krpano.com/docu/xml/#view seems outdated info..

i also see camroll.. thats a gyro plugin thing isn't it? i'm not sure if you can put that there..

Hi,

your fovmin is larger then your fovmax setting:

Quoted

fovmin="100" fovmax="80"
This is wrong and causes the constant jumping between these values every frame.

Btw - you can also update to the latest krpano version, there the fovmin/fovmax settings were checked for correctness and this will not happen anymore too.

Best regards,
Klaus
