Project 2 (implementation of the paper Surface Simplification Using Quadric Error Metrics) of the course Computer Graphics, 2019 Spring, Tsinghua University.
Use g++ -o mesh_simp mesh_simp.cpp -std=c++11 -O3 to compile the code.
Use mesh_simp <input_model> <output_model> <simp rate> <dist threshold> to run.
