Im on windows i would like to have a .exe file which is a 3d viewer, similar to blender.
Which language do i code it?
Which libraries would i need to use?
Note: when i mean creating my own 3d engine i mean that i would do myself the maths, i dont want a prebuild one
Thanks


This, 100%. Use whatever language you’re fast and fluent with. If you don’t have any of those yet, C is a good choice. Get books and tutorials from the 90s or 2000s and OpenGL is a great place to start.
The most limited resource that you have to manage would be your own energy and passion. Don’t go out and seek that dopamine hit of validation from others until you’ve built something. “I want to build something” is OK, but “I’ve started building something, it runs somewhat, here’s a repo, I’m stuck, HAAAALP!” is way more compelling.
