# Weakly compressed liqiud simulation

- The code is mainly code transplanted from [SPlisHSPlasH](https://github.com/InteractiveComputerGraphics/SPlisHSPlasH)

- The code use [Taichi](https://github.com/taichi-dev/taichi) programming language

---

## Current implement algorithm

* [SESPH] 

* [PCISPH]

* [IISPH]

* [DFSPH]

---

## How to run 

* First config your anaconda workspace, and open the anaconda prompt

* Second you need install [taichi](https://github.com/taichi-dev/taichi) language, **pip install taichi**

* Last you type **ti dfsph.py**, that's all
