## What it is
A particle-based fluid simulation built in Unity with C#, implementing SPH-style methods from academic papers. It includes GPU-accelerated fluid rendering and was developed as an educational project with accompanying videos.

## Use cases
- simulate fluids with particles in Unity
- learn SPH fluid simulation
- study GPU-based fluid rendering
- explore particle-based physics simulation code
- reference implementation of fluid dynamics papers

## When to choose
- you want a readable, educational fluid simulation in Unity
- you need a starting point for particle-based SPH in C#
- you want to learn how fluid rendering effects are implemented

## When to avoid
- you need a production-grade CFD solver
- you need fluid simulation outside Unity or in another engine
- you need high-accuracy engineering-grade fluid dynamics

## Facets
- artifact type: application
- maturity: active
- function: simulation, graphics, image-processing
- domain: simulation, graphics, education
- platform: game-engine, cross-platform
- tags: fluid-simulation, particle-simulation, sph, unity, csharp, gpu-rendering, educational, game-development, desktop
