Libigl Botsch-Kobbelt Local Remesher

Implementation of the local remesher from "A Remeshing Approach to Multiresolution Modeling" by M. Botsch and L. Kobbelt, to work with the libigl geometry processing library. Can be used as a Command Line Tool, a C++ function, a Matlab mex function and a python function. Python bindings can be built from this repository, or found as part of gpytoolbox

Important note

An up-to-date, maintained version of this code is implemented into our new python geometry processing library Gpytoolbox. See the remesher documentation and examples here.

Installation

Clone this repo and its submodules:

git clone --recursive git@github.com:sgsellan/botsch-kobbelt-remesher-libigl.git

To build this project, do the usual CMake dance:

mkdir build
cd build
cmake ..
make -j

Setting the Path

Once you built the project, a script setpath.sh will be copied to your build folder. Run source setpath.sh to add the path to the build folder to your system PATH and PYTHONPATH environment variables.

Use

To run in command line, issue

remeshmesh [input.ext] [output.ext] [-i num_iterations] [-h target_edge_length]
[-p]

The mesh in input.obj must be closed and manifold. ext can be any of obj, mesh, off, ply and stl. -p tells the remesher to project to the original mesh.

To use within your own C++ code, simply the header files in src/ and use the function remesh_botsch as shown in remesmesh.cpp.

Python bindings are also available:

from pyremesh import remesh_botsch
v_new, f_new = remesh_botsch(v, f, target, steps)

I also provide a mex wrapper for Matlab, which can be compiled by running mex/build_mex in the Matlab console. A precompiled Mac OS X mex binary can also be found in precompiled/osx/bin.
