Hi Tom, I do think that is is one (of many) ways to get pleasing flat pictures from spherical panoramas. If it could be included within Panini that would be great; at the moment I either need to use mathmap where the image is too small to see what I am doing or I need to use a two step process which is slow.
Let me know what I can do to help. Best wishes, Peter. From: Tom Sharpless <[email protected]> Subject: [hugin-ptx] Re: Recentred equirectangular projections.
