You can open "VSFM/dense.nvm" inside "vsfm-project.zip" using VisualSFM to see the reconstructed project. It contains the sparse point cloud, the dense point cloud and the textures. If you want the image thumbnails to work properly, you need the directory "../../2 Lens Corrected Subset" containing the lens corrected images relative to the "dense.nvm" file. If you keep the directory elsewhere, you need to adjust the paths in "dense.nvm".
