How to make such sites?

Question

3D

Hello people, in which direction should I look or learn in order to create sites with 3D capabilities, such as these ?

Answer 1

В сторону WebGL (наиболее низкий уровень) или готовых веб-движков: Three.js, Blend4Web.
Плюс, нужно хорошо знать геометрию, желательно матричную алгебру и аффинные преобразования.

Answer 3

Phew, finally opened (sirinlabs.com). True, he did not particularly go to firefox, but it worked in chrome. :)
Yes, WebGL. And you were given very good advice on using ready-made frameworks: Blend4Web and ThreeJS . In the first case, this is a full-fledged framework with good documentation, an editor and all sorts of goodies, in the second case, it is more of a library, but there are more programming examples on it. And pure WebGL, IMHO, is only for programmers.

I see what speed it is and this site loads more than 30 seconds, I know how to do this but I won’t say it because these are extra show-offs, this is not why users go to sites
