Thread:


I looked at your postproduction file and I liked it a lot. It is a 
fascinating video and I am interested in similar works.
Anyway I found two problems:
- files are too large and take forever to download. I suspect that 
really few people had the patience to wait so much.-
- the image is too wide to fit in my screen (1280x1024) so I can only 
see the central part and I cannot control the movie.

Surely handling the whole project is a very heavy task for ptgui. I am 
working at a similar (but smaller) work: a single photo taken handheld 
almost every day from the same location.
Letting ptgui create control points among all the photos is makes the 
program run too slow, so I create control points between two consecutive 
photos only. Then I sometimes add control points between a photo and the 
first one, just to avoid a progressive shift in the photo positions.
In this way I can also load only a limited number of images: I only need 
to always load the very first one for control points creation. So I can 
load the first image and all the images taken in a month, optimize and 
save them. Then I can load the same first image and the following month 
images, optimize and save them being sure that they will match.

Maybe you can work in a similar way: create control points among the 
images of the same pano and those of the previous one only, then 
sometimes create control points among a pano and the first one. Load 
only some images at a time, to save time.

I suspect that you will have to review the control points created by 
ptgui looking for wrong ones, mainly in the near field.

Good luck!
