Entire high of flat pano

bazaar · September 19, 2009 at 8:12 PM

Hello,

i has a question about flat partial panoramas i export in multires with krmultires..

All panos i export are configured to see the entire large seen. excellent for horizontal panoramas.

But i wondered for vertical panoramas, where are the lines to change to have all the high of vertical panoramas?

Thank you!!

Greets,

Xavier

Hi bazzar,

I am not absolutely sure but, looking at the doc, it seems that the vfov is automatically calculated if not set manualy.

Quote from krpano 1.0.8 beta (Flash10, QTVR, Zoomify, Partials Panos, ...)

Partial and cylindrical panos:
krpano supports now also partial spherical and cylindrical panos.
the view is automatically limited to the area of the image (limitview="auto"), but it's necessary to set "fisheye" to "0" for correct limiting.
new parameters for the image tag:

"hfov" - hortizontal field of view of the image (default=360)
"vfov" - vertical field of view of the image (default=automatically calculated)
"voffset" - vertical offset (default=0)

If I am not on mistake, this is possible because three datas are known: the image width, height and the hfov....

Then, try the same way as always you do.

Hope this can help.

Salut.

Thank you Michel,

but this doesn't work... if spherical if selected, this ask you for hov, but both 5° or 50° answer return bad results, and only entire larger of vertical panorama..

And for flat pano, nothing is asked...

Bye,
Salut :)

OK,

this should be those parameters:

Quote

limitview
possible values:
"off" - no limiting
"auto" - automatic limiting (default)
"range" - limit to the area set by "hlookatmin","hlookatmax","vlookatmin","vlookatmax"
"lookat" - limit the lookat angle to "hlookatmin","hlookatmax","vlookatmin","vlookatmax"
(when using range limiting the fisheye effect should be set to 0)

But i haven't found yet the exact parameters to see all higher of the pano, and to see it in the center of screen...

So,

i think this could seem that:

Quote

<view hlookat="0"
vlookat="0"
fov="5"
maxpixelzoom="1.00"
fovmax="5"
limitview="range"
hlookatmin="-5"
hlookatmax="+5"
vlookatmin="-1,5"
vlookatmax="+1,5"
/>

Display More

But i have a problem: when i go out of the picture at screen, i can't come back into it...
Someone have any solution?

Thanks,

Xavier

Hi bazaar,

Can you give a link to see what is going wrong? I am confusing in trying to understand the problem.

here is the kind of panorama:

http://www.xavierspertini.com/demo/vitrail/

with this code:

Quote

<view hlookat="0"
vlookat="0"
fov="5"
maxpixelzoom="0.75"
fovmax="5"
limitview="true"
hlookatmin="-2.5"
hlookatmax="+2.5"
vlookatmin="-1.3"
vlookatmax="+1.3"
/>

Hi bazaar,

I have found this about simulating a flat/2D pano (hfov=1):

Quote from krpano 1.0.8 beta (Flash10, QTVR, Zoomify, Partials Panos, ...)
XML example - simulating a flat/2D pano (hfov=1):
Code
<krpano>
    <view fisheye="0" fovmin="0.01" />
    <image type="SPHERE" hfov="1">
        <shpere url="flatpano.jpg" />
    </image>
</krpano>

Perhaps this can help.
Anyway, waiting see your link.

Salut.

Hi Xavier,

The better <view> code I have found was this one:

Code

<view hlookat="0"
vlookat="0"
fov="2.61"
maxpixelzoom="0.75"
fovmax="2.61"
fovmin="0.01"
limitview="lookat"
hlookatmin="-0.4"
hlookatmax="0.4"
vlookatmin="-1.25"
vlookatmax="+1.25"
/>

Display More

fov="2.61" is from the aspect ratio of your image. ratio = 1 : 2.61
hlookatmin + hlookatmax would sum 1 ...... hlookatmin="-0.5" hlookatmax="0.5"
vlookatmin + vlookatmax would sum 2.61 .. vlookatmin="-1.3" vlookatmax="1.3"
To avoid extreme zoom pan left right up down to be centred, I have reduced a little each value.
I my opinion, it would be better to disable the mouse usercontrol giving some buttons to navigate.
I do not know if something better is possible.
Better would be to limit the view on a hfovmax and vfovmax basis. (do not know if I explain well here)

Hope this can help.

Salut.

Hi,

just to let know - the next krpano 1.0.8 beta 9 - has an automatic mode for displaying the pano at full height (size),

best regards,
Klaus
