Web 3D 框架简介

前言

3D游戏引擎的历史可以追溯到20世纪80年代末和90年代初。当时，计算机技术迅速发展，人们开始对图形和游戏感兴趣。以下是3D游戏引擎的历史故事：

早期引擎的诞生（1980-1990年代）

在这个时期，一些早期的3D游戏引擎开始出现。其中一个著名的例子是id Software开发的Doom引擎，该引擎是第一个在主流市场上取得成功的3D游戏引擎。它采用了一种被称为"重建"的技术，可以在限制的硬件资源下实现3D效果。

商业化时代的到来（1990-2000年代）

随着3D游戏的普及，商业化的3D游戏引擎开始涌现。其中最著名的是id Software开发的Quake引擎，它是第一个具有实时3D渲染和支持网络游戏的引擎。Quake引擎的成功推动了更多的公司开始开发自己的3D游戏引擎，如Epic Games的Unreal Engine和Crytek的CryEngine。

开源引擎的崛起（2000年代后期）

在2000年代后期，一些开源的3D游戏引擎开始崛起。其中最著名的是Unity引擎，它提供了一个友好的界面和工具，使得游戏开发者可以轻松地创建和发布游戏。此外，还有一些其他开源引擎，如Ogre3D和Godot等，它们也受到了广泛的关注和采用。

HTML5和WebGL的兴起（2010年代）

随着HTML5和WebGL技术的发展，3D游戏引擎开始向Web领域扩展。这使得开发者可以在浏览器中创建和运行高质量的3D游戏，而无需额外的插件。一些主要的Web 3D游戏引擎，如Three.js和Babylon.js，开始出现，并得到了广泛的使用。

Web 3D 框架

Unity 3D ，团结引擎，基于 Unity 2022LTS。是 Unity 中国研发团队推出的 Unity 中国版引擎，专为中国开发者定制的实时3D引擎，它以 Unity 2022 LTS 为研发基础，推出了微信小游戏解决方案、团结引擎车机版，赋予小游戏和智能汽车领域的开发者，以更强劲的创作动能，是 Unity 中国加速本土化进程的里程碑。

使用Babylon.js小试牛刀

Babylon.js inspector 检查器是一个可视化调试工具，旨在帮助您确定场景中可能存在的问题。
提供多种工具，如：
场景的层次视图
使用多个特性栅格可以动态更改对象特性
特定的辅助对象，如骨架查看器等
