Hey folks, I've been working on a cave survey drawing program in VR (after spending the last two decades doing the conventional cave survey drawing program TunnelX: https://github.com/goatchurchprime/tunnelx/
I think it's a lot more fun to use, and simpler because you're not trying to represent something that is fundamentally 3D in a technical 2D diagram. And you can edit it over the network in real time with other people.
There's a release here, which works on the PC (if it doesn't have VR then you can steer it with mouse and keyboard). https://sidequestvr.com/app/1630
But if you've got an Oculus Quest (now retailing at £300), it runs pretty well on that.
I'm looking for anyone with an interest who wants a demo (it's networked, so I can guide you from within the game).
