This model is part of a complete tutorial on the Allegorithmic website ([find it here](https://www.allegorithmic.com/blog/go-scan-world-photogrammetry-smartphone)). The goal was to obtain a high fidelity scan for texturing with a simple smartphone!
For this example, we used a Samsung Galaxy S6.
In this Sketchfab project, all maps are uploaded in 4K and the tessellation was done before (from the Height Map).
