TinyMesh is a light-weight mesh processing library in C/C++

Modules

Here is the list of modules and reference papers for that.

• Smoothing
  • Laplacian smoothing
  • Taubin smoothing [Taubin 1995]
  • Implicit fairing [Desbrun 1999]
• Denoising
  • Normal Gaussian filter [Ohtake et al. 2001]
  • Normal bilateral filter [Zheng et al. 2011]
  • L0 mesh smoothing [He and Schaefer 2013]
• Remeshing
  • Uniform triangulation [Hoppe 1996]
• Simplification
  • Quadric error metrics (QEM) [Garland and Heckbert 1997]
• Hole filling
  • Min-area hole filling [Barequet and Sharir 1995]

Install

The module is tested its compilation using the following compilers.

• Windows - Visual Studio 2019
• MacOS - Apple Clang 11.0 (MacOS 10.15)
• Linux - LLVM Clang 10.0, GNU C Compiler 9.4.0

Library and examples (C++)

You can build a shared library and all the examples by CMake with the following commands.

git clone https://github.com/tatsy/tinymesh.git --depth 1
cd tinymesh
git submodule update --init --recursive
mkdir build && cd build
cmake -DCMAKE_BUILD_TYPE=Release -DBUILD_EXAMPLES=ON ..
cmake --build . --config Release --parallel 2

Python module

You can install the Python module using Pip.

pip install git+https://github.com/tatsy/tinymesh.git

You can also use poetry to install from source codes.

git clone https://github.com/tatsy/tinymesh
cd tinymesh
poetry install

Notice

The functions provided by this repo are not perfect and their process will fail for problematic meshes, e.g., with non-manifold faces. In such cases, you can fix the problem by repairing the mesh using MeshFix.
