1) Unzip and copy the files to a \raster3d folder. 2) Add it to your PATH 3) Use DOS Command shell, to use raster3d executables. Command line options are same as on a UNIX workstation. 4) If you want to use UNIX shell scripts on Windows, for example stereo3d, and Raster3D.sh; you will need to install Cygwin (http://www.cygwin.com). The binary executables were compiled using GCC from MinW32. They are native Win32 binaries. These binaries are not linkied to Cygwin1.dll. Suhaib Siddiqi
