Virtual reality programming?

Question

Programming

Hello, I'm interested in the topic of virtual reality .
Several questions have appeared
1. What exactly do programmers do in this area?
as I understand it, you can program games for it or program the helmets themselves, or am I mistaken?
2. In what languages ​​is all this done?
3. Are there any video courses, books, specifically blogs on how it's all programmed, on the internal structure (possible in English)
4. Who else is in this area besides programmers? Well, that's for sure designers, who else?

Answer 1

Virtual reality, even with a helmet, is exactly the same toys, only there are two screens, and they are in front of the user's nose.
For a programmer, it makes no difference.

Answer 2

Nirazu didn’t do anything under VR - I’m writing from general considerations
As elsewhere
- hardware
- software
- support

2. In what languages ​​is all this done?

* forget about video training. It is for beginners. People will write any hardcore information , but they won’t record videos in a vlog on YouTube

4. Who else is present in this area besides programmers? Well, that’s for sure designers, who else?
