Smoothed Particle Hydrodynamics Unity

Very basic implementation of realtime fluid simulation using the SPH algorithm.

File Breakdown

• Raymarching.compute : A Compute Shader used for the Ray-marching (simplified version from Sebastian Lague)
• SPHComputeShader.compute : A Compute Shader running SPH w/ various kernels that operate on different segments of SPH
• SPH.cs - Controls the SPH Compute Shader
• FluidRayMarching.cs - Controls the Ray Marching Compute Shader

WIP

• Adding refraction & transparency to visuals
• Adding physical interaction between a rigidbody & water

Version 3

Simple Lego Renderer for the Fluid Simulation based on this video https://youtu.be/LrEHoaq6QFE (feat/lego-renderer)

Version 2

Optimized SPH with 32,000+ particles using Dynamic Hashed Grid (feat/optimization)

Version 1

Contains basic ray marching & very un-optimized SPH.
