The Polygon Mesh Processing Library is a modern C++ open-source library for processing and visualizing polygon surface meshes. Its main features are:

• An efficient and easy-to-use mesh data structure
• Standard algorithms such as simplification, remeshing, subdivision, or smoothing
• Ready-to-use visualization tools
• Seamless cross-compilation to JavaScript (demo)

Clone the repository:

git clone --recursive https://github.com/pmp-library/pmp-library.git

Configure and build:

cd pmp-library && mkdir build && cd build && cmake .. && make

Run the mesh processing app:

./mpview ../external/pmp-data/off/bunny.off

Build your own tool:

#include <pmp/SurfaceMesh.h> int main(void) { pmp::SurfaceMesh mesh; mesh.read("input.obj"); // .. do awesome things with your mesh mesh.write("output.obj"); }
