How to make a custom 3D model for a website?

Question

JavaScript

Hello.
There are two tasks, I wanted to ask experts how best to implement and where to dig. Both tasks are related to the 3D model
1. 3D model of the house, next to it is a menu for choosing and changing the roof, walls, environment and other elements of the house. There are a lot of textures, you can't make a picture for each option - you need automatic texture substitution
2. 3D model of a person (mannequin). A person enters data into the fields (height, waist, etc.) - the mannequin adjusts to the parameters and you can try on clothes on it (the clothes adjust accordingly to the person’s parameters).
What is the best way to implement this? On flash/js or something else in general? Maybe someone knows good articles on this topic or live examples of the implementation of such tasks?

Answer 1

Theoretically, webgl + threejs.org engine

Answer 2

Check out blend4web.com . Somewhere on their site, I even saw a ready-made example of a custom mannequin.
