Inverted cone view

[ecs1749]

For some unknown reason, after correcting a number of issues, the Quicktime VR movie I created becomes like an inverted cone view (imagine standing at the bottom of an inverted cone looking up):

as oppose to the far more pleasant street view:

I have no clue what I did to cause this. The jpg was created by using Hugin, and the Quicktime conversion was created using Pano2QTVR.  The jpeg appears to be normal:

So, I am assuming I selected something when stitching that caused this.  Anybody?

I wonder if this is caused by missing nadir...but shouldn't that be just a patch of black area?

Have you tried one of those viewers to see the jpg directly?

  Hi ecs1749!

   Have you checked the vfov (vertical field of view) of the image? Perhaps the interactive viewer is set with a wrong value.

Both are displayed wrong. Both don't cover 180� vertical field of view.
The first one is stretched to the nadir, the second is stretched to both
nadir and zenith. Your source images apparently are cylindrical ones.
Just check "Cylindrical"on Pano2QTVR Project tab (IIRC - it's some years
now since I used it last...).

In Hugin, I clicked "Calculate" and it gave me the values of HFOV 360 and VFOV of 180.

I used Hugin and stitched using Equirectangular - not Cylindrical.

You're image is obviously not a 360x180, you're missing both zenith
and nadir. If you give this image to PanoCube, it will simply tell you
that the ratio is incorrect (should be 2x1).
Just add data up and down so that you have the correct ratio (usually
if I'm missing some sky I just choose some blue for the top, and
usually some dark colour for the bottom). Then run again PanoCube or
Pano2QTVR.

Thanks.  That is indeed the problem.  Dealing with the sky continues to be a headache.
