网格简化作业

2022秋实时三维图形基础课小作业之一,复现Surface Simplification Using Quadric Error Metrics

原论文

目录结构

基于课程提供的框架(这个框架好像很大程度上来自于中科大的图形学课...?)。本项目目录包含以下若干子目录:

  • _deps/: U开头的依赖项
  • data/: 见下
    • models/: 作业所需的三维模型文件
    • shaders/: 着色器文件,其中部分文件需要大家填写补充
  • include/_deps/: stb_image.h,供图像处理使用
  • src/: 本次作业项目的源代码
    • _deps/eigen: EIGEN库的头文件
    • app/: 主要部分的代码
      • main.cpp: 和上一次作业框架基本相同,用于渲染展示,无需修改
      • MeshSimplification.cpp: 请大家完成这一文件中的函数
    • tool/: 工具代码,包括三维模型加载、摄像机移动

实现效果:./网格简化.mp4
(这之后还改了些bug,但没再录.)
