a clone cpp graphics library inspired by three.js.
I pick google's angle as a direct replacement for WebGL which three.js depends on,hence, I can concentrate on computer graphics itself.
Now I first run it on MacOS Apple Silicon and Windows desktop with angle by libEGL + libGLESv2.
有感于three.js基于图形学的知识在web上几乎从头开始搭建了一个优秀的图形学框架，并且提供了无数的精彩例子。three.pp，基于google angle实现，以three.js为蓝本，使用cpp语言学习实现跨平台的本地渲染框架，目前已经实现的功能：
- 完成渲染引擎部分功能的移植
- 基于MacOS Apple Silicon平台的运行
- 基于win64 系统的运行
- 实现了2个线段绘制例子
- 迁移了obj/mtl loader，实现了obj/mtl解析加载功能，并实现一个例子
- 实现了一个buffer geometry，无顶点数据绘制例子
- 实现多点光源动态实例
- 实现基于光源的物理真实（PBR）渲染例子
