Looking at the full stitched version vs. the full morphed version, the stitching error in the full morphed version (where the silver pole crosses the boundary between the top and second to top window of the glass windowed cabinet) is surprising for the described method, though I expect a few control points could fix it. The overall shape differences are more concerning. That specific scene is one in which broad shape differences are hard to visually parse. So I can't validate my guess that in other examples the shape change of that method would be too big. Both the big shape change and the issues of chaining the methodt across more photos are reasons that I was thinking of the morph as a fine tune on top of existing methods, rather than as a replacement. For many examples, just the morph would be a lot better than the existing methods, so it is sad that you didn't have time to pursue that as another choice within the Hugin GUI. >From that discussion: > Panotools also uses a not-very-nice distortion where it splits the image up into triangles and performs an affine transformation on each triangle separately That is certainly what I had in mind (possible just because I don't know better ways). I expect that using this as a fine tune, rather than as the primary method, would eliminate the problems with that method. Anyway, thanks for providing a lot more information on this topic than I expected to get (even though I have significant learning to do before I can try using any of that). -- A list of frequently asked questions is available at: http://wiki.panotools.org/Hugin_FAQ --- You received this message because you are subscribed to the Google Groups "hugin and other free panoramic software" group.
