## About this project

This project implements the following mesh deformation methods:

- biharmonic deformation

- As-Rigid-As-Possible (ARAP) deformation

## Content

This repository contains the following directories and files:

- `input/`:  input meshes provided with homework indstructions.

- `plots/`:  HTML files generated by Meshplot.

- `hw2_practical_code_report.ipynb`: our report, including necessary code.

## Requirements

Meshplot is required to display the meshes.

```bash

conda install -c conda-forge meshplot

```

libigl python bindings are required:

```bash

conda install -c conda-forge igl

```

The following libraries where also used:

- `IPython`: to display the meshes inside the notebook (workaround).

- `numpy`: for math operations.

- `scipy.linalg`: for linear algebra operations.

- `scipy.sparse`: for sparse matrix objects.

- `scipy.sparse.linalg`: for sparse matrix operations.

- `sksparse.cholmod`: for testing positive definitenes using Cholesky decomposition.
