+A library for modelling and processing 2.5D terrains using a (2D) Delaunay triangulation.
 The triangulation is computed in 2D, but the *z*-elevation of the vertices are kept.
 
 The underlying code is written in [Rust](https://www.rust-lang.org/) (so it's rather fast) and [robust arithmetic](https://crates.io/crates/robust) is used (so it shouldn't crash).

   3. interpolate with several methods: TIN, natural neighbours, IDW, Laplace, etc.
   4. use other useful terrain Python libraries that are also NumPy-based, eg [laspy](https://laspy.readthedocs.io), [rasterio](https://rasterio.readthedocs.io), [meshio](https://github.com/nschloe/meshio)
