Answer 3

first and foremost, your question is so much general and somehow vague in terms of buiding a 3D game.
Please consider that, the core of every single 3D and lots of commercial 2D games is their graphics engine or renderer-- generally just called engine by folks -- which is chiefly has been written in c++ (even in assembly. e.g. the physics simulator of Quake Engine).
Another important areas of coding in terms of 3D game engines are:
Physics engine
AI engine
Sound engine
animation handler
scripting engine
networking handler
memory management system

and so much more, depending on the level of complexity and expectation.
