Blender Stack Exchange is a question and answer site for people who use Blender to create 3D graphics, animations, or games. The 2D/3D Stitching Plugin is able to reconstruct big images/stacks from an arbitrary number of tiled input images/stacks, making use of the Fourier Shift Theorem that computes all possible translations (x, y[, z]) between two 2D/3D images at once, yielding the best overlap in terms of the cross correlation measure. An imgvol file is a simple text file that has the names of the slice images in it along with a couple of optional keywords to specify Z-origin and Z-spacing. If the list is 2D (or in python-speak a list of lists) then the inner list is taken as a number of sub images which should be binned together. I didn't tried PyOgre either, but you might want to check out PyGLet, I don't really know what it is, but it looks great.
