## What it is
CinoLib is a header-only C++ library for processing polygonal and polyhedral meshes, supporting triangle, quad, and general polygon surface meshes as well as tetrahedral, hexahedral, and general polyhedral volume meshes. All mesh types share a single abstract base class, letting the same algorithms run on any mesh type without code duplication.

## Use cases
- process triangle and quad surface meshes in C++
- generate and manipulate tetrahedral and hexahedral volume meshes
- compute geodesic distances on meshes
- write geometry processing algorithms that work on any mesh type
- convert between surface and volumetric mesh representations
- mesh generation for simulation and graphics pipelines

## When to choose
- you need a unified data structure handling both surface and volumetric meshes, including general polyhedra
- you want a header-only C++ library with no build dependencies
- you work in geometry processing research or computer graphics with mixed mesh element types

## When to avoid
- you only need triangle mesh processing and prefer a more battle-tested tool like libigl, VCG, or PMP
- you need GPU-accelerated or highly optimized rendering-focused mesh code
- you need a non-C++ language binding

## Facets
