how to limit the pitch in 360x180 tour while making the tour?

by digipano » Mon Oct 25, 2010 8:20 am

Sometimes the room is not so good looking or has some unwanted details in zenith or nadir which we would not want to show but the whole tour is actually done as 360x180.

I was thinking if while making the tour can we restrict the pitch parameters by locking vertical FOV so the viewer does not see the zenith & nadir?

Only thread I found Renan say that I have to manually crop the image but that does change the horizon line & add some extra work to guess, where as doing that in APT should be easy but I find no such option of doing so within APT.

The Crop tool in the Hotspot Editor - in fact a virtual crop tool - does just that.

Just crop to the limits of what you wish the viewer to be able to see.

You need to be using the latest beta of APT or Panotour:

Hi digi!

If you want to make it in an individual node:

Just go to your xml - like this one:
<view fisheye="0" limitview="lookat" vlookatmin="-90" vlookatmax="90" fovmin="30" fovmax="90" fov="90" hlookat="33.25" vlookat="-0.08"/>

and set: vlookatmax="25" or what you need.

("-" means "up" here - so if you look down it´s without "-").

If you want to make if global use Andrew´s advise.

best, Klaus

The Autopano Tour/Panotour Crop tool is not 'global' it's per-'node' (to use your terminolgy).

In other words you can crop, or not crop, each image in a tour separately and independently.

I see - but how to set it in a way it only limits the downward angle? How do you calculate the vertical offset to do so?
And how would you make it after you already built a tour? You can´t - you have to generate the tour again.

You see: it´s VERY simple do do it afterwards by changing just ONE number in the xml file related to the dedicated pano in the tour . . . . :cool:

Thanks to Mediavets & klaus
both method works but restricting the nadir also restrict the zenith at +90 pitch,
after cropping in APT zenith cannot be viewed beyond +90 pitch,
uncropped version allows to view full zenith upwards beyond +90.

Any way out so the cropping works in any one side not restrict both?

That's always the case whether cropped or not - unless you change things by editing the XML.
uncropped version allows to view full zenith upwards beyond +90.

No it doesn't - well not for me with Panotour Pro beta 2 on Windows XP SP3 and viewing tour with latest Firefox. I can see the zenith (+90) centre screen, but I cannot go 'over the top'. Can you?

Sorry I meant I see exact zenith center with uncropped version whereas after cropping it goes upto +80pitch.

Again I can't agree - if I crop at the nadir to avoid viewing the tripod area then I can still centre the zenith on the screen.

Can you post a screenshot of your crop? Could it be that you are (unintentionally) also cropping at the upper edge of the pano?

Here's mine - this rather nasty 360x180 has a particularly 'dirty' zenith so it's obvious in screenshots.:

Editing the xml in my eyes definitely is preferable. You can set Nadir completely independent from Zenith.
So if you have shot a Zenith but not a Nadir you can just restrict the downlook-angle without affecting the
uplook-angle.

And as I keep telling you, so you can using the crop tool - it is not a symmetrical crop you can adjust every edge separately, as my example above shows.

Oh and of course you can't edit the XML if (unfortunately) you only have Panotour, and not Panotour Pro!

Klaus I agree with mediavets that doing that in GUI is better so you know the precise FOV (in some cass each tour may need different VFOV) & can see it happening within gui.

Mediavets I was only seeing in GUI & it seems there is a bug (or may its intended to work like that) that shows a restricted zenith within the application but on your insistence I actually exported the whole multinode tour & yes I confirm that in the exported tour the zenith is fully visible & only the nadir is restricted

See screenshot of panoour pro APT does the same too

The whole purpose of GUI should be to show us the "Real" preview of our tour settings which in the present case it does not do so, infact I would like to see even the buttons/html template/ & the drop down menu or whatever output its going to give us based on the settings.

Aaah...now I see - I'd never tried viewing the zenith in the 3D Editor after cropping in the Hotspots Editor.

I'd call that an 'undesirable feature' at the very least - I suggest you post it as a bug here:
