Linux binaries are recommended.
Montage is one of the first serial reconstruction packages, and it remains one of the best.
It was originally written for a z80 system with floating-point hardware, and has since been ported to Venix, and, most recently, Linux. The digitization program runs best in Linux's svga mode, but the driver can easily be re-written for another system, and the entire source compiles with gcc, to ensure portability. One is Tom Chou's contour picker and surface tiler, which produces a surface composed of triangles for AVS's geometry viewer. The source code for this method is available by request. The other, Nuages, is in the initial stages of investigation.
