Tank 3D Scanning is a quite complex field because tanks are huge, they present a lot of occluded areas, sharp edges, and small details. This year is the 100th anniversary of the Renault FT (operational use in 1918), the first modern light tank in History!
3D Capture of the Renault FT
We 3D Captured a Renault FT at the Armored Vehicles Museum of Saumur, we used photogrammetry because we wanted high-quality textures, and we had developed powerful photogrammetry workflows for subjects of that size.
The capture was a bit challenging; The overall lighting was quite low/directional, and there wasn’t too much space to move around the subject. (It’s not that easy to move a 12600 kg tank !). We used short lenses for close range capture.
You can check the 3D Scanned tank in real-time using the Sketchfab viewer below. Feel free to try the Sketchfab VR / AR Features!
If you want to see the tank in real-life, make sure you visit the Armored Vehicles Museum of Saumur.
Tank 3D Scan: Soviet 2S3
We also scanned an old Soviet 2S3, a self-propelled gun developed in 1968. The capture conditions were better, and this specific 2S3 has really interesting texture details.
Reconstruction produced a nice point cloud of one Billion points!
We decimated the mesh to a decent number of polygons, here is a preview of the raw decimated mesh.
To maximize texture quality, we unwrapped the model using 8 UDIMs, final output was an 8K map per UDIM.
You can check an optimized version of the model on Sketchfab :
Scanbox Vehicle 3D Scanning Service
3D Scanning of Armored vehicles is great for Cultural Heritage. But it can also be really helpful for Video Game / VFX projects, providing an excellent base for modelling/texturing.
