RealityKit - Mapping real world textures based on LiDAR scan (not Photogrammetry)

I want to build an app that lets devices with the LiDAR Scanner scan their environment and share their scans with one another. As of now, I can create the mesh using the LiDAR Scanner and export it as an OBJ file.

However, I would like the ability to map textures and colors onto this model. How would one go on to get the real world texture and place it onto the OBJ model?

To be clear: I am not referring to Photogrammetry in RealityKit 2.0 since that relies on a macOS device. I would like to achieve what apps like Polycam and Scaniverse are able to achieve

Thank you!

There's still no API for LiDAR realtime textures from Cupertino engineers. – Andy Jazz Aug 14 '21 at 15:50
Do you know how apps like Polycam are able to do it? Would love to use something like that or even an SDK which makes this possible. – HeySaiK Aug 14 '21 at 17:33
I've been trying to find out about it for a long time... – Andy Jazz Aug 14 '21 at 18:35

Ooof that’s rough. Thank you though, please let me know if you figure it out – HeySaiK Aug 14 '21 at 20:59

My question is still valid. – https://stackoverflow.com/questions/63793918/lidar-and-realitykit-capture-a-real-world-texture-for-a-scanned-model – Andy Jazz Aug 15 '21 at 07:26
