This is a GPU-based particle system, which enables the simulation of fluid, fire, and collision phenomena. The fluid simulation employs the Smoothed Particle Hydrodynamics (SPH) method [7], while the rendering of a 3D model is achieved through GPU Instancing using particles.

This project is developed using C++(C++ 20), with a dependency on OpenGL 4.6. It utilizes the itugl package.
It can not run in MacOS because of the Compute Shader. Please goto the https://www.khronos.org/opengl/wiki/Compute_Shader to get more information about Compute Shader.
You can build this project using cmake. Follow the steps below:
- Navigate to the source code directory.
- Create a new directory named
build. - Move into the
builddirectory. - Execute the command
cmake ...
