Technologies used in game creation?

Question

3D

Hello.
1. What technologies can be used to create similar 3d or 2d objects?
2. How can you "synchronize" 3d models and program code? For example, I want to create a program in C #, but how can I connect 3d models in the program?
Combine everything. Just creating a 3d model by itself is not that difficult. I don't quite understand these things. Use Unity?
I can't even formulate the question specifically, sorry. In which direction to dig?

Answer 1

1. Ordinary 3d editors.
2. Learn Unity.
