## What it is
A modern C++ open-source library for processing and visualizing polygon surface meshes. It provides an efficient mesh data structure, standard geometry processing algorithms like decimation, remeshing, subdivision, and smoothing, plus ready-to-use viewers and JavaScript cross-compilation.

## Use cases
- decimate or simplify large triangle meshes
- remesh a surface to improve element quality
- subdivide a coarse mesh for smoother surfaces
- smooth noisy mesh geometry
- fill holes in scanned meshes
- compute geodesic distances on a surface mesh
- parameterize a mesh for texture mapping
- visualize and inspect OBJ/OFF polygon meshes

## When to choose
- you need a modern, MIT-licensed C++ alternative to OpenMesh for surface mesh processing
- you want standard geometry processing algorithms out of the box with a clean data structure
- you need to compile mesh processing tools to JavaScript/WebAssembly for the browser

## When to avoid
- you need volumetric or tetrahedral mesh processing rather than surface meshes
- you need rendering features beyond simple mesh viewers (use a full graphics engine)
- you work primarily in Python or another language without C++ interop

## Facets
- artifact type: library
- maturity: stable
- function: graphics, simulation, image-processing
- domain: graphics, developer-tools
- platform: cpp, cross-platform, wasm
- tags: mesh-processing, geometry-processing, surface-mesh, remeshing, mesh-simplification, subdivision, smoothing, parameterization, geodesic-distances, hole-filling, triangulation, curvature, algorithms
