Fluid Simulation

This project is a GPU-accelerated 2D fluid simulation built in Unity using a hybrid of Smoothed Particle Hydrodynamics (SPH) and Eulerian grid-based methods. It leverages C# scripts and HLSL compute shaders to achieve real-time, interactive fluid behavior.

🎮 Features

• 💧 Hybrid Fluid Simulation

  • SPH for particle-based dynamics and surface detail
  • Eulerian grids for stable pressure projection and boundary handling

• ⚡ Real-Time Performance

  • GPU-parallelized via HLSL compute shaders
  • Efficient particle neighbor search and pressure solver
  • Optimized for interactive use in Unity scenes

• 🎥 Interactive Visualization

  • Real-time visual feedback in Unity Editor
  • Adjustable parameters for simulation behavior
  • Supports basic UI input for experiments and tuning

🧪 How It Works

SPH (Smoothed Particle Hydrodynamics)

• Particles represent fluid parcels
• Density and pressure calculated using smoothing kernels
• Forces: pressure, viscosity, external (e.g., gravity)

Eulerian Grid

• Pressure projection step solved on a 2D grid to enforce incompressibility
• Combines well with SPH for stability and boundary handling

GPU Acceleration

• All major computation steps run in parallel using HLSL compute shaders
• Optimized buffer management and thread grouping for speed

🛠️ Technologies

• Unity (URP compatible)
• C# (simulation logic, data orchestration)
• HLSL (compute shaders for physics)
• Unity Compute Buffers & Shader Dispatching
