Fast Marching Python

This repo is a python wrapper of the fast marching algorithm for computing geodesics on a triangular mesh. The code is modified from gproshan.

Note

Fast marching is an approximate algorithm, for exact geodesics, see gdist.

Dependencies

1. Eigen3
2. OpenMP
3. Pybind11 (already contained in this repo)

Usage

1. Compile the code:

    cd fast_marching/fast_marching 
    mkdir build 
    cd build
    cmake -DPYTHON_EXECUTABLE:FILEPATH=python3 ..
    make 

2. Run the test.py file for demo. The input is mesh directory and the output is a square matrix recording the pairwise geodesics among all vertices.
