Geometry-Processing-Boolean-Operation

A toolkit for some basics operations used in mesh boolean operation

Dependency

• libigl
• Eigen
• boost/multiprecision

Get started

git clone https://github.com/Ziheng-Liang/Geometry-Processing-Boolean-Operation/
mv MakefileTemplate Makefile

Modify the Makefile so it gets your dependent library

make
./main

Example

Triangle triangle intersection:

#include <Eigen/Dense>
#include <bol/triangle.h>
#include <iostream>
#include <vector>
int main()
{
  using namespace igl::bol;
  Matrix33r A, B;
  A(0,0) = 0;
  A(0,1) = 0;
  A(0,2) = 0;

  A(1,0) = 0;
  A(1,1) = 2;
  A(1,2) = 0;

  A(2,0) = 2;
  A(2,1) = 0;
  A(2,2) = 0;

  B(0,0) = 0;
  B(0,1) = 1;
  B(0,2) = 1;

  B(1,0) = 0;
  B(1,1) = 1;
  B(1,2) = -1;

  B(2,0) = 1;
  B(2,1) = 1;
  B(2,2) = -1;
  std::vector<RowVector3r> r = igl::bol::t2t_intersect(A, B);
  for (int i = 0; i<r.size(); i++){
    std::cout << r[i] << std::endl;
  }
