javascript - 为什么让衣服适合3D模型在javascript中如此困难？(Why is making clothes fit a 3D model so dificult in javascript?)

Question

My apologies in advance if this is not a proper question.

(如果这不是一个适当的问题，我事先表示歉意。)

I am asking this purely out of curiosity.

(我纯粹出于好奇而问。)

I am growing as a developer and gaining more knowledge because of this I actually realize how little I know.

(正因为如此，我正在成长为一名开发人员并获得更多的知识，所以我实际上意识到自己所知不多。)

I am definitely not expecting any form of code or solutions.

(我绝对不希望有任何形式的代码或解决方案。)

I basically want the smart people in our community to explain to me in the most child-like understandable form why this is so hard.

(我基本上希望社区中的聪明人以最像孩子一样易懂的方式向我解释为什么这么难。)

I only found 2 questions related to this issue which I'll link.

(我只找到了2个与该问题相关的问题，我将它们链接起来。)

1: An algorithm that automatically fits clothing?

(1： 自动适合服装的算法？)

2: Modelling clothing in C++

(2： 用C ++建模服装)

My question basically boils down to this:

(我的问题基本上可以归结为：)

1:Why is making clothes fit a human 3d model such a difficult thing to implement in Javascript or similar framework?

(1：为什么要使衣服适合人类的3D模型这么难在Javascript或类似框架中实现？)

I have seen examples where people have made a human 3D model in Javascript.

(我看到了一些用Java制作人类3D模型的示例。)

Why doesn't the fashion industry have something like this so people can give their measurements and know exactly how clothes would fit them before ordering?

(为什么时尚界没有这样的东西，以便人们可以给出自己的测量结果，并在下单前确切知道衣服的摆放方式？)

I mean surely things like this are already present in video-games where if the character grows or shrinks so do the clothes around their body.

(我的意思是肯定像这样的事情已经出现在电子游戏中，如果角色成长或收缩，那么他们身上的衣服也一样。)

2:Render clothes in 3D based off a picture and necessary information.

(2：根据图片和必要信息以3D渲染衣服。)

If I understood it correctly, to make things fit on models you have to make a 3D model design for it before it can be used.

(如果我正确理解它，则要使其适合模型，必须先对其进行3D模型设计，然后才能使用它。)

But what if this 3D model was generated temporarily realtime based on specs?

(但是，如果此3D模型是根据规格临时实时生成的，该怎么办？)

Is this something so heavy that it would only be available in countries with fast internet?

(这太重了，以致只能在具有快速互联网的国家/地区使用吗？)
