I have spent a few days with Ryan's 64bit build of hugin, and I think "wow!" is the best way to summarize the experience so far. Here are a few observations:
I set the memory usage for enfuse and enblend to 7GB. Both went upto the limit while stitching a large project with no issues. I also noticed nona got upto about 5GB and hugin itself got to 3GB, even though I had the image cache set to 500MB. A 17k wide 360x180 blended/enfused equirectangular projection from 125, 70MB, 16bit TIFF files stitched in 72min! Previous projects took about 5hrs. I tried one autopano-sift-c test case for 15 images with --maxdim 4000 set and it found over 3000 control points. Typically, I have found the previous versions have issues adding control points when -- maxdim is set to > ~1200. I also tried adding a Nadir with these settings, and ~10 control points were found for all adjacent images, which never happened in previous runs. The optimizer really didn't seem much faster. Still only used about 12% of cpu resources. Overall hugin interface was a bit perkier, especially when dealing with control point editing and cropping. Both preview windows were more responsive. I had issues with every previous build where I would get a boost thread resource error about 1 in 5 times when adjusting the projection in the regular preview screen. For this build, I could not make it crash! Not a single crash since I started testing on large projects! At times, I have had a project active over days, without closing or re- starting. Definitely a much improved user experience for large projects. It looks like from the discussion threads that not many people in the user community are dealing with such large projects, but that is all I work with. This build certainly makes that work more pleasant! I understand that it should not be critical path for 0.8.0, but it would be a great enhancement for the next release.
