I work on Vircadia (https://vircadia.com/) and have been thinking for a while that it would be cool to have in-world visualizations of things like the project's structure and github activity. It's a big one, so perhaps the right 3D representation would make the project's structure more understandable at a glance.
The multiplayer aspect is immensely valuable. Having multiple developers walk around the same codebase together, discussing the architecture and the code, is helpful for debugging, onboarding, brainstorming, all the different ways we collaborate as developers. This kind of visualization is not a solo activity, so I can see where Vircadia would come in.
How do you navigate it? How do you search for text in VR?
What do you visualize exactly?
Is it a static or a dynamic display? Can you drill down to actual lines of code?
How do you deal with large projects? Vircadia has 400K LOC and 11K files.
