Installation Instructions

Installation is as simple as unzipping and extracting the archive. The archive has been gziped. When you extract the archive, it will be placed in a directory PVT.



You will notice a new directory PVT, the binaries are stored there. You need to add this directory to your path in order for the shell scripts to work properly. If you just want to view the results you can simply copy the FMTViewer program to the particular examples sub-directory (i.e. climber) that you are interested in.


The archives have been compressed using winzip. Simply open the archive in winzip and extract the contents. For best results you need to add the location of the binaries to your path and the glut32.dll file to your dlls. In order to use the script files that reproduces the results you need some software that emulates a Unix Bourne shell. Our software has been tested with the software from MKS, however Cyngnus provides free UNIX utilities for Windows platforms. To simply view the example results using the FMTViewer program you do not need any shell script emulation. If you just want to view the results on Windows you can simply copy the FMTViewer executable and glut32.dll to the particular examples sub-directory (i.e. climber) that you are interested in.

The mks toolkit is available via ftp from If you install the toolkit it will work as a demo for 30 days. Having installed it take all the individual commands in the PVT directory and move them to MKSDemo (default on your C drive) in the directory mksnt. Then copy one of the examples directory, which must also be unzipped into MKSDemo. Then run the MKSDemo software, Korn Shell emulation. You will be in a unix shell emulator.


Simply go into one of the examples (i.e. examples1/climber) and type the following: The same sequence of commands is what you use on the unix systems and Windows. The MKS toolkit just emulates a Unix shell on Windows.


For a quickstart download and extract the examples and go the sub-directory you are interested in. To view the results execute the displayit shell file for Unix/Linux, or the displayit batch file for Windows. Look at the computed quantities for a particular image triple by cycling through up arrow, down arrow; look at different image triples by cycling through left and right arrow. Check the epipolar geometry by clicking on any point (try one in the middle image) with the left mouse button. To start you can look at the final supporting tensor correspondences that were used to make the reconstruction by typing down arrow to see the correspondences between images in RED; then right arrow to cycle through the sequence showing the correspondences for any image triple. For more display options read the accompanying FMTViewer documentation.

Each subdirectory also contains a VRML file (.wrl extension) which has the reconstruction results obtained from sending these final tensor correspondences along with the camera calibration to the Photomodeler program. This VRML file can be viewed using any VRML viewer, such as Cosmo. Many VRML viewers are available as plugins to the common browsers.
