Fluid Simulation

This repository contains a personal OpenGL practice project by Zhang Kun. It implements a very simple particle-based fluid visualization demo using C++ and OpenGL.

The simulation is closest to a basic SPH-style particle fluid model rather than a grid-based Navier-Stokes solver. The code includes particle initialization, neighbor lookup with a simple spatial grid, density estimation with a smoothing kernel, pressure and viscosity terms, gravity, and OpenGL point rendering.

The project is kept as an early graphics and simulation exercise. The source files have been moved to a direct src/ layout so the repository is easier to browse.

Main Ideas

• OpenGL/GLFW window and point rendering
• 3D particle initialization
• Simple box/grid structure for neighbor search
• SPH-style smoothing radius and density kernel
• Pressure and viscosity force terms
• Basic boundary box visualization

Dependencies

The original project was developed as a Visual Studio/OpenGL program and used:

• OpenGL
• GLEW
• GLFW
• GLM

The Dependencies/ and src/vendor/ folders are kept from the original project structure.

Notes

This is an old personal OpenGL learning project. It is mainly useful as a record of early practice with particle simulation, OpenGL rendering, and basic SPH-style fluid mechanics code structure.
