Using 360 images for previsual work in accurate real world scale
Hi I have some heavy 3D environments/scenes not originally optimised for VR and thus simply will not render at a performant level and FPS for obvious reasons. Ideally it would be great to take 360 ...
Late to the discussion, sorry, but for what it's worth...
I starred this gist on github many years ago: https://gist.github.com/khadzhynov/24f26234b7ffc9e683049e13143b450e
It's a shader for adjusting the scale and y offset (horizon height) of a skybox cubemap in Unity. Not used it for a while but should still work.
The further discussions you had about enabling 6dof within 'flat' stereoscopic rendered views is also interesting. There are perhaps other ways of doing what you're trying to (if I understand the problem correctly). Google Seurat would have been exactly what you needed, if it haden't been deprecated by Google https://developers.google.com/vr/discover/seurat (See: https://www.youtube.com/watch?v=FTI_79f02Lg) It's possibly still doable if you're able to refactor the code from the archived github repos: https://github.com/googlevr/seurat and the unity plug-in: https://github.com/googlevr/seurat-unity-plugin.
There's a demo on the Quest store (sorry, Horizon Store 😁) that I'm pretty sure uses this technology. Forest – Oniri Tech Demo. I think the company have essentially taken Seurat and implemented it into their own system which is a paid platform very much geared at enterprise (architectural visualisation, that kind of thing) https://www.oniri.space/ By trying out the demo you'll be able to experience both its strengths (very high quality pseudo 3D on mobile) and its weakness (the illusion is only sustained within a small area, which is why you need to teleport from point to point).
The other technologies that come to mind, if the environments you want to capture are not CG but real, are Lightfields (The demo from google Welcome to lightfields was done in Unity) and an example project can be found here: https://github.com/PeturDarri/Fluence-Unity-Plugin.
But also the work that Varjo have just annouced 'Teleport' https://varjo.com/teleport/ / https://varjo.com/press-release/varjo-demonstrates-teleport-a-powerful-new-service-for-turning-real-world-places-into-virtual-experiences/ which looks like it could be a game changer for allowing 3D gaussian splatting to run on any standalone headset
