PBR Rendered Fluid Simulation

---

shortShowcase4.mp4

This is a realtime fluid simulation and renderer made in Unity. The features include

• Particle-Based Fluid Simulation based on Smoothed Particle Hydrodynamics (SPH) run using Compute Shaders
• Physically Based Raymarched Fluid Renderer written with HLSL
• Physically Based Screenspace Fluid Renderer written with HLSL (faster than raymarched but not as accurate)
• Particle-Based Foam Simulation for crashing waves run using Compute Shaders
• Foam rendering using using volumetric raymarching or billboard sprites written with HLSL
• Raymarched Rendered Caustics and Shadows
• Screenspace Rendered Caustics and Shadows
• Spatial Hashing and different GPU sorting algorithms to allow the simulation to run at high framerates
