Hi, i usually do 360 degree virtual tours for customers, however i have had a customer who wanted approx a 160 degree panorama taken and then inputed to look like a virtual tour, once you get to one side you scroll back the other way (ie 359 degrees). I have stretched the image a little to give the ratio of 3:1 however when inputed i get severe distortion. The only way can get it to look relatively normal is when i use a Input FOV Horizontal 60 and Vertical about 20 with a default view of approx 40 degrees using Speherical projection and then ir pretty much looks like a planar projection

Can anyone please point me in the right direction on how to make this 160 degree pano look like a traditional (or as close as possible) VR tour.

Any help ASAp would be appreciated!

Thanks in advance!

(image 1 attached is source file unedited but stitched together - Stretched)
(image 2 attached source file unedited straight out of the panorama editor)

Cheers

I used the following script:

1) Take the picture and drop it in the KRPANO droplet MAKE (NORMAL) pano droplet.bat. If you don't have KRPANO, get it if you have Panotour Pro you allready have a license.

2) The KRPANO droplet askes you to fill in the HFOV of the pano......type in 180 and press <ENTER>

3) Look at the Pano by opening the appropriat just created HTML.....

4) Be disgusted since the horizon is not on in the centre and curved

5) Open the .xml saved with the name of the pano

6) Change the setting voffset to 20 and save

7) The horizon is now straight.

Next time when a client asks you a question like this you have to shoot a full 180 degrees vertical sphere (and a 180 degrees horizontal sphere) and then do the same trick as I explained in steps 1 and 2.

Advantages:

1) Youre horizon will be in the middle
2) Youre builings won't be distorted due to the voffset change
3) You will have the desired half sphere effect you are after

I am 'lost' - why not just input it in Panotour as a partial panorama?

Stitch and render the pano using a spherical projection (panotour obnly handles images with spehrical or planar projections).

You can get the precise pano HFOV, VFOV, and vertival offset values - for entry in Panotour - from the Kolor EXIF tag in the stitched pano image, Panotour will reda this data automatically from the EXIF unless you have lost it by pre-processing the image prior to input to panotour.

When viewed the partial pano will go/'scroll' back and forth automatically if you have set autorotate.

Hi Mediavets, maybe i am missing something here. I simply open Panotour Pro, press the add panorama image and it gives me a unusable tour, with a severely distorted horizon.

I have used the stretched version and the version with the black on top. I am unsure of what to do to get a useable result.

Any help would be greatly appreciated.

I should add, this was stitched in PTgui

actually, i think i just worked it out. Use the Image with the black, then use the crop funtion in PanotourPro and works.

I am only using the low res file i have uploaded as i have left the full res at the office but it seems to be working

You have to enter the correct Input Field of View data if your pano does not have a pano FOV of 36x180.

If you had stitched the pano you could have found the values in the Kolor EXIF tag - see screenshot.

If you stitch with PTGui you'll have to obtain the values some other way.

I guess you are aware that you cannot produce iDevice compatible tours using PTP 1.8 unless all the panos in the tour have a HFOV of 360 degrees and min. VFOV of more than 45 degress?

Yes, you could force the pano FOV to 360x180 when stitching, and then crop in PTP 1.8.

But you have to use a 'hack' to crop on the H axis of a pano with a HFOV of 360.

And as I recall - with tours created using PTP 1.8 - the H crop will not be acknowledged by the HTML5/javascript Panorama Viewer when you view on an iDevice, only the V axis crop.

ahhh damn i tried to export for a idevice and it wont let me tick the Ipad option (which is what the client needs)

So what your saying is that pretty much the only way to get this to work is if i purchase AutoPano Pro??

No; what I'm telling you is that all panos used in a tour built with PTP 1.8 that you wish to view with an iDevice must have a HFOV of 360 and a VFOV of more than 45 degrees - see screenshot from PTP 1.8.

The krpano HTML5/javascript Panorama Viewer 1.0.8.14 incorporated in PTP 1.8 - used when viewing iDevice compatible tours - does not support panos with a HFOV of less than 360 and a VFOV of less than 45 degrees.

It may be different with PTP 2.x.

As I mentioned before you could froce the stitch to a 360x180 panoFOV then crop in PTP 1.8.

The crop is virtual it doesn't actually cahnage the dienmsnion s of the pani image, instead sets viewer limts.

However to crop on the H axis of a ano witha 360 HFOV you have to use a simple 'hack' - change the HFOV to 359 in the Field of View settings manually, then crop on the H axis then change HFOV back to 360.

However as I recall when viewed on an iDevice the V crop is honoured but not the H crop.

You could find out for yourself.

Ask Kolor via the Contact form to register you on the Kolor VIProom forum set up to support pre-release testing and use of PTP 2.x. There you will find download links and can obtain peer support with developer input.

Ok good news, we are getting closer. I have used your "hack" and it loads fine on a idevice, te H Crop is honoured. Instead of it being a 359 degree pano how i would like it (not spining around on itself)it is a 360. I have edited the xml and input 359 and this doesnt work, i have tried to keep it as 359 in program and it wont let me save for a idevice.

we are getting very close, any ideas would be great!

I think you mean the V(ertical FOV) crop is honoured?

If the H(orizontal FOV) crop was honoured there would be no problem.

yes you are correct, sorry was a typo.

Any ideas on how to get it to 359 and not 360? It is so close to complete...

Have a look at this - it was created with PTP 2.x alpha 18:

http://www.three60views.org.uk/2a18-partial/2a18-partial.html

It displays a partial pano that was forced to 360x180 when stitched and then cropped on both axes in PTP 2.x. - yes, it stll requires a variant of that 'hack - see screenshot

If it displays correctly when viewed with an iPad then you have the answer to whether PTP 2.x is the solution.

I don't have access to any iDevices to test it myself.

thanks for all your help, i really do appreciate it. I have found a solution using pano2vr. Not the best solution, it is a little messy but the result will suffice.

The link you provided does work on a ipad.

If using partial panos in Pano2VR you will still have to enter the correct pano FOV data for it to display correctly.

Then why not upgrade to PTP 2.x?

It's currently at Alpha 18 status, still not quite complete and with some remaining bugs - but quite usable for many purposes and it offers alot more support for mobile devices - and not just iDevices - and many other new features.

You can upgrade from your Kolor web shop account.
