# Filters

Filters are operations that change the whole mesh or a selected subset of faces. Polygonal currently provides the following filters:

- [Triangulation](#triangulation) --  Triangulate polygonal faces
- [Subdivision](#subdivision) -- Refine the surface using subdivision
- [Remeshing](#remeshing) -- Improve the shape of triangles
- [Decimation](#decimation) -- Reduce the number of triangles
