This is a repository for my 3D version of a SPH Langarian fluid simulation using my own rendering engine SpectraWise-Engine. The implementation is using OpenGL 4.6.
My 2D implementation version can be found here: Fluid-Simulation-2D

Download the repo to you computer. Generate the build file with CMake and just go crazy! All of the Fluid simulation files is in the Engine->Physics folder.

• Cleanup code!
• Make Compute shader work
• Make 3D bound better looking
• Apply stickyness to the particles to mimic water better.
• Implement a simple Rigidbody to particle collision system
• Experiment with Spheretrace rendering for water.
• Implement simple lights
• Make water reflective.
• Make bound rotate.
• Possibillity to export and import to 3D softwares like Houdini.
• Add liquid presets
• Implement a usable UI
• Add better movement
• Implement input manager
• Implement quick reset of shaders
• Add possibilities to change from 2D to 3D
• Add possibilities to change from CPU to GPU Calculations
• Add possibility to import and export Universal Scene Description(USD) files.
• Dynamic color gradient in water.

Would you encounter any bugs within the simulation, please create an issue and report it!

• Viscosity infinity energy loop. (Making infinity swirls in corners)
• Compute shader implementation not working.
• Pressure going crazy when the fps is below 40.
