I'll try and explain where this is going... A long time ago Pablo figured-out that the best interface for passing input to a control point generator is to give it a .pto file and for it to return the same .pto file with control points added. This is because there is potentially a huge amount of information that can be passed: lens parameters, stacks and positions can all be useful for generating control points. Up until now, the only tool that supports this interface is autopano-sift-c, but we didn't have a tool for creating these input .pto files. So this is what match-n-shift now is, at its most basic you give it a list of photos and it creates an unaligned .pto project for those photos. e.g. you can now select some photos in a file manager, right-click, and instantly create a .pto project: http://www.flickr.com/photos/36383...@n00/4238784980/ This project can be used as input for autopano-sift-c, or just open it with Hugin; Align... and Stitch... Alternatively you can now use 'ptoanchor' to add control points to this project. ptoanchor actually does everything that the Hugin Align.. button does, plus it intelligently deals with both kinds of bracketed panoramas. ptoanchor is just a wrapper around all sorts of other command-line tools, it runs so many sub-processes, many of them potentially in parallel, that is uses a Makefile and gnu 'make' to do it. This is analogous to the current Hugin stitching system which uses 'make' to manage the stitching process - Actually it is so similar that it wouldn't be difficult to plug this into the Hugin Batch Processor and have end-to-end alignment and stitching. So although these tools are fully usable as they are, this is actually a prototype design for a more flexible way of dealing with the Hugin Align step: to make it scriptable, distributable, parallel, batchable and debuggable, but still work within the GUI as it does now.
