Remeshing of a triangular mesh for making high quality Delaunay triangulation?

I have a triangular mesh of the brain surface. I want to remesh it to a high-quality Delaunay triangulation. I'm seeking an easy and straightforward method.

You can use JIGSAW for surface (re)meshing. Similarly to CGAL, it offers various Delaunay-based methods to discretise planar/surface/volume domains, with a focus on high quality mesh creation.

Though JIGSAW itself is a c++ code, you can run it directly from either MATLAB or Python. To install, you'll need a c++ compiler and cmake. Click through to GitHub for additional instructions and examples.

**I'm a developer of JIGSAW, so keep this in mind I guess! Otherwise, in addition to CGAL, the MMG or Geogram packages may also be of interest.

pygalmesh interfaces CGAL and has surface remeshing. Install CGAL, then install pygalmesh with

pip install pygalmesh

Then you can use

pygalmesh-remesh-surface lion-head.off out.vtu -e 0.025 -a 25 -s 0.1 -d 0.001

on the command line. enter image description here

You mean that you want to resample the mesh? I've had some success using the trimesh package: https://github.com/mikedh/trimesh

Check out trimesh.remesh in particular.

I'm not sure if C++ is an option for you but the CGAL library provides such a functionality. See this package, see in particular this example.

If you want to use a GUI, you can use the CGAL polyhedron demo. You can compile it yourself by compiling the code in demo/Polyhedron from a release or use the pre-compiled windows demo available: demo + dlls to be extracted in the directory of the demo. Load your input mesh, select it and click on Operations -> Tetrahedral Mesh Generation -> Create a Surface Triangle Mesh
