**hypertiling** is a high-performance Python library for the generation and visualization of regular hyperbolic lattices embedded in the Poincare disk model. Using highly optimized, efficient algorithms, hyperbolic tilings with millions of vertices can be created in a matter of minutes on a single workstation computer. Facilities including computation of adjacent vertices, dynamic lattice manipulation, refinements, as well as powerful plotting and animation capabilities are provided to support advanced uses of hyperbolic graphs. 


## Installation

hypertiling is available in the [PyPI](https://pypi.org/) package index and can be installed using
```
$ pip install hypertiling
```

For optimal performance, we highly recommand to use hypertiling together with `python-numba`, which, if not already present on your system can be installed automatically using the `[numba]`-suffix, i.e.
```
$ pip install hypertiling[numba]
```
The package can also be locally installed from our public [git repository](https://git.physik.uni-wuerzburg.de/hypertiling/hypertiling) via
```
$ git clone https://git.physik.uni-wuerzburg.de/hypertiling/hypertiling
$ pip install .
```


## Quick Start

In Python, import tiling object from the **hypertiling** library

```python
from hypertiling import HyperbolicTiling
```
Set parameters, initialize and generate the tiling

```python
p = 7
q = 3
nlayers = 5

T = HyperbolicTiling(p,q,nlayers) 
```

Further usage examples and a full API reference are available in our [documentation](https://gitpages.physik.uni-wuerzburg.de/hypertiling/hyperweb/doc/examples/quickstart.html).

## Examples


### Tilings

The core functionality of the package is the generation of regular hyperbolic tilings projected onto the Poincare disk. Tilings in the upper row are centered about a cell, in the lower row about a vertex.

### Refinements

The hypertiling package allows to perform triangle refinements, such as shown here

## Applications

### Hyperbolic Magnet
Simulation of a Ising-like Boltzmann spin model with anti-ferromagnetic interactions on a hyperbolic (7,3) tiling, quenched at low temperature. The hyperbolic antiferromagnet (left) exhibits geometrical frustration, whereas on a flat lattice (right) an ordered anti-parallel alignment can be observed.

### Helmholtz Equation
Solution of an electrostatic Helmholtz problem on a refined (3,7) tiling, where boundary values have been fixed to either -1 (red) or +1 (blue). One readily recognizes a field value separation according to geodesic arcs in the Poincare disk representation of the hyperbolic plane.
