TFG_FluidSimulation2D

1. Introduction

1.1 Description

• This tool enables the simulation of fluids in a 2D environment within Unity, providing realistic visual effects of moving fluids. This tool uses an already existing fluid simulation method called smoothed particles hydrodynamics.
• Example:
  

The assets used in the example scene and the gif above are from brullov

1.2 Requirements

• The tool has been tested on Unity 2022.3.3 and 2021.3.3 but it should work on Unity Versions 2020 as well.
• Since this tool uses compute shaders, it is important to check that your platform support compute shaders in order to this tool to work. Here you have a list of platform that support them (List extracted from Unity Documentation).
  • Windows and Windows Store, with a DirectX 11 or DirectX 12 graphics API and Shader Model 5.0 GPU
  • macOS and iOS using Metal graphics API
  • Android, Linux and Windows platforms with Vulkan API
  • Modern OpenGL platforms (OpenGL 4.3 on Linux or Windows; OpenGL ES 3.1 on Android). Note that Mac OS X does not
    support OpenGL 4.3
  • Modern consoles

  1. Open Unity and create a new project or open an existing project.
  2. Go to Assets > Import Package > Custom Package.
  3. Select the downloaded package and click Import.

3. Initial Setup

3.1 Adding the Fluid Simulation to the Scene

1. How to add the main fluid simulation package/Tool to a Scene:
   • Add the FluidSimulation prefab from the Assets to the Scene.
2. How to adjust the Prefab with the needed information, In case it was not already set:
   • After clicking on it you will have to set some things in order for it to work.
   • Required Shaders
     • The Compute shader FluidSimulation2Compute
     • The Particle Instancing Shader Custom/Particle
