How do you like this way of optimizing the game?

Question

JavaScript

I have an idea:
If you make two 3d objects instead of one!
1 is a normal object with a large number of vertices and a good texture
2 is an optimized object with a minimum number of vertices and a simplified texture
and, depending on the distance from the camera, replace objects
Example:
camera close to the object > hide 2 and show 1
camera far from the object > hide 1 and show 2
What do you say? Is there any reason??? you just need to make your own editor for webgl to implement this (((

Answer 1

This is called LoD - https://ru.wikipedia.org/wiki/Level_of_Detail
Really used for a long time and often.
About the editor - it is not clear why it is needed.

Answer 2

That's what they do in a lot of games.

Answer 3

I think all advanced engines support it. From what I know, there are definitely in Unity, Unreal and Blend4Web.
