Meshroom is a free, open-source 3D Reconstruction Software based on the AliceVision Photogrammetric Computer Vision framework.


Luminance HDR is a graphical user interface (based on the Qt5 toolkit) that provides a complete workflow for HDR imaging.



Enblend combines images that overlap into a single large image with no seams. Enfuse combines images that overlap into a single image with good exposure and good focus.


insight3d let’s you create 3D models from photos. You give it a series of photos of a real scene, it automatically matches them and then calculates positions in space from which each photo has been taken along with a cool 3D pointcloud of the scene.

PixelStruct is an opensource tool for visualizing 3D scenes reconstructed from photographs. It uses the opensource structure-from-motion system Bundler, which is based on the same research as Microsoft Live Labs Photosynth.
