Yup. I'm doing a VR project, urban environment. Haven't really found a good enough solution for 3D reconstruction from images.

Yes, there is gaussian splatting, NeRF and derivatives, but their outputs _really don't look good_. It's also necessary to have the surface remeshed if you go through that route, and then you need to retexture it.

Crazy thing being able to see things up to scale and so close up :)

Not meta VR, but one of my favorite things to do in gran turismo 7 with my PSVR2 is just “sit” in the cars and look around the cabins. The level of detail the devs put in is on another level.

Would be nice if they modelled real purchasable cars this way. With functional knobs and hud would be even better.

Knobs in cars are not a thing anymore... No need for 3D for that ;-)

Instead they have to model screens and the operating systems that allow us to change the temperature with only 6 clicks!

A number of manufa turers are heading back to knobs for frequent functions after customer sentiment whiplash.

I love simracing in the rain (rf2 is really punishing in particular and actually looks quite good) mainly for similar reasons.

I find it much easier to remesh and deal with textures with a crappy 3d reconstruction vs working with 2d images only. I also shoot HDRI and photos for PBR. I find sculpting tools super useful for VR, but yeah its still an Art even with all the AI help.

If you use "*" instead of "_" you can write in italic :) just a thought

By output you mean the extracted surface geometry? Or are you directly rendering NeRFs in VR.

Given the scale it wouldn't be wise to render them directly. There's also the issue of being able to record in real life without changes happening while doing so.

I should've have clarified it, but yes I was talking about the extracted surface geometry.
