Cleaning up Photogrammetry Meshes in Blender

1

Photogrammetry (the process of reconstructing 3D models from images) is awesome, but often generates heavy and 'noisy' meshes. You'll need to manually clean up the results afterwards to make them usable.

Hello dear Blenderheads,

I've made a video showing part of the cleaning process of an architectural photogrammetry model, it's one of the rooms of "Cappella dei Notai", Palazzo della Ragione in the center of Verona, Italy; the paintings are by Louis Dorigny (1654 - 1742).

The environment has been acquired during a 5 hours photogrammetry session, Aegis Scan created a 1.8M tris model, that was reduced to 500k in Meshlab.

After the cleaning the model has been imported in Unreal Engine 4 for VR realtime rendering and interaction.

I hope you enjoy the video, happy blending!
