Where to start learning to develop 3D sites?

Question

3D

This is ideal for me) But everything is much simpler in my plans. Question: what base do I need to study in order to develop a website with 3D elements? I already imagine how thorny this path is and how many skills you need to have, but my eyes run wide

Answer 1

First you need to set the task of what you want.
Do you want just a couple of 3D blocks or complex animations like these ?
If it's just a couple of blocks - go to CSS transformations, they are good at it.
If you want something cool, then you need a good knowledge of JavaScript.
As you were told in the comments, learn how to create simple sites. When you learn, the questions will disappear.
Go to basics. On the web, the basis of complex 3D is WebGL.

I can already imagine how thorny this path is.

Can't imagine. Here, try to master the basic tutorial on 3D in WebGL .
When you can't in the WebGL API, google Three.js or Babylon.js, but it won't help much.
