Simulation. It takes a lot of effort today to bring up simulations in various fields. 3 D programming is very nontrivial and asset development is extremely expensive. If I have a workspace I can take a photo of and just use it to generate a 3d scene I can then use it in simulations to test ideas out. This is particularly useful in robotics and industrial automation already.

I don't see any examples of a 3D scene information usable for simulation. If you want to simulate something hitting a table, you need the whole table (surface) in space, not just some spatial illusion effect extrapolated from an image of a table. I also think modelling the 3D objects for simulation is the least expensive part of an simulation... the simulation is the expensive thing.

I doubt this will be useful for robotics or industrial automation, where you need an actual spatial, or functional understanding of the object/environment.

With research like this you need to start somewhere. The fact we can get 3d information helps. There are people looking into making splats capture collision information [1].

I have worked on simulation and in my day job do a lot of simulation. While physics is oftem hard and expensive you only need to write the code once.

Assets? You need to comission 3d artists and then spend hours wrangling file formats. Its extremely tedious. If we could take a photo and extract meshes Im sure we'd have a much easier time.
