Hi Helmut I would second (or is it third?) Terry's and Yuv's request.
I've long wanted to see 'morph-to-fit' -- meaning a more general mesh based warping engine -- added to Hugin's repertoire. If PTStereo showed the way to that, it would be a very good thing. In fact the 'fast transform' code now in libpano is almost a mesh warper, but restricted to a regularly spaced flat rectangular mesh. It would be great to have a general 3D triangular mesh, with an appropriate coordinate interpolator and perspective projection onto the picture plane, as in OpenGL. Of course some mesh generating functions would be needed too, but far less complex than what is now common in 3D modeling. As you know, my Panini warps images by projecting a mesh using OpenGL. After developing Panini, it has become clear to me that this would an excellent way to prepare images for stitching: very general, and, if implemented on 3D rendering hardware, very fast too. My only hesitation is the low order of pixel interpolation offered by current GPU languages -- but that will probably change as the next generation hardware becomes common, and I suppose it is already possible to get better interpolation with a pixel shader program.
