» » Maw | Hi,
first of all I wanna say Hi to the world of 360°
I´ve a pano-head here and made a panorama of 8 photos and stitched it with Stitcher 5.6.0 for Mac OSX.
I rendered the project as a spherical Image. (Better as a cylindrical image??)
It looks like this:

So i cut away the black room at the top. At the bottom I brushed the floor with the stamp tool and now it looks like this:

Than I opened this panorama in Stitcher and rendered it as a cylindrical QTVR. I thought that it would be a nice globe (of course not at the top but at the bottom I thought). But it has a black hole at the bottom where the tripod was.
But why is that? I stamped the floor and there is nothing black at the floor in my Image
So what´s the problem?
It looks like this, and the carpet isn´t straight anymore as you see:

And I also saw some time, that people makes their Logo in a circle at the bottom where the tripod stands. How can I do this?? Best regards,

Jim Scott | Hi MAW!
I think you best off using the spherical approach - you can limit the tilt of of your QTVR so you don't see the black hole in the top or the tripod head below (we'll get to the "logo at the bottom" in a bit).
Please refer to the Stitcher Manual for more details about specific steps.
You can accomplish this tilt restriction by using Stitcher's "QT Movie Settings" in the "Render" dialog.
Unfortunately, v5.6.x of Stitcher does not support the "QTVR Preview" function (in "QT Movie Settings" ) when rendering from stitched images. This makes it very tough to make accurate settings.
One workaround for this problem:
----------------------------------------
Render to spherical (or cubical) - then import the rendered spherical back into Stitcher using the "Load Panorama..." command ("File" menu). If you still have an open project you will first need to select "New" from the file menu. You can now convert the spherical into a QTVR. Under this rendering scenario the "QTVR Preview" function in "QT Movie Settings" does work.
Note: You can drag the image in the "QTVR Preview" dialog itself to the location you wish to be the "Default" (opening) view for your QTVR - as well as set it in the numeric entry boxes.
It is of course annoying to have to do this two step process if you simply wish to render straight to a QTVR after stitching.
==================================
And now we get to your "logo on the bottom" question which should mitigate the sting of the double render process described above.
In order to place a logo at the bottom (nadir) of a QTVR you need to render your fully stitched pano to "Cubical Image" (a collection of six faces - images - that make up a cubical projection).
Note: Use TIFF, not JPEG for this step; otherwise you'll compress your image twice - once in the cubical render and once again when creating the final QTVR, thereby losing image quality.
Select a location for these files (a separate folder is convenient) and render.
Open the bottom face in an image editor and paste in your logo. Save/Close this image.
Now in Stitcher select "Load Panorama..." (not "Open" ) from the "File" menu. If you still have an open project you will first need to select "New" from the file menu.
Select just one of the faces in the "Load Panorama..." dialog - the rest will import properly.
You can now adjust your rendering parameters - including use of the "QTVR Preview" - and render. Message edited by Jim Scott on 05-04-2008 at 07:17:41 AM ---------------

Maw | oh wow, dis works very good nice - thank you very much for writing this!
one question with the quicktime preview. I´ve loaded a one-row panorama image (spherical) and in the stitcher window and wanna render it as cylindrical QTVR. If I watch the preview, the black holes ar cropped away, so that I only see my panoramic image (it has straight borders because it is already croped). In the quicktime Preview I can move vertically from -14.225 till 14.356°.
If I want to only move vertically from -10° to 10 degrees, I replace the -90° to 90° in the Tilt min and max.
So it is now Tilt min: -10° and Tilt max: 10°
I press the preview again I am not able to move vertically. (default value is always at 0)
If I change min max values to -20 and 20 I can move from -9,99999 to 9,9999
Why´s that? I thought I can move now from -20 to 20? (but remember before I wrote, that normally I can only move from -14,... to 14.... (in the default field I saw this)
Funny... if I change from -30 to 30 I can move from -20 to 20 (so remember the 14,... I must see the black hole at bottom and top now, but that isn´t so. I only see a pretty small section.
I hope you understand my "problem" ;-)

Jim Scott | Hi Maw!
I am not fully able to understand your problem.
If you constrain (limit) tilt values too tightly the panorama will not tilt - the vertical field of view (VFOV) imposed by the tilt values is smaller than the VFOV in the QTVR window itself.
The best thing to do is experiment to find the tilt values that work for a particular QTVR, I do not have any more insights about these settings.
Also there is the "Define render area" setting (in the "Render" menu > "Render Area" tab) that might prove useful for your cylinder QTVR output. Check the Manual for more details about this setting. ---------------

Maw | okay thank you very much, I will check the manual for some detail problems - but the panoramas becoming better and better - Stitcher is really the nicest programm for panoramas I think - also because of the Workflow... |
