Pannini Again

Pannini as intended, 230°

Pannini as intended, 230°

After I published samples of the new libpano projections in Hugin, Bruno found that Daniel’s implementation in libpano does not perform like his original Mathmap implementation. Daniel started a thread to unify the opinions on what the projection should look like, and the result is that Hugin now has two new projections instead of just one: Pannini (Bruno’s) and Equirectangular Pannini (Daniel’s). The name will be corrected to reflect the correct spelling of Giovanni Pannini, the Italian painter who inspired Bruno’s research. As of SVN revisions 921 (libpano) and 3577 (Hugin) this is not yet the case, but the functionality is not affected.

Another interesting finding is that Pannini’s projection is the same as the Recti-Perspective projection that Max Lyons will introduce in the next version of PTAssembler, the most advanced of the proprietary stitchers in terms of post-processing projections.
