# FluidEngine
This is a fluid simulation engine for computer graphics applications. I adopt it from Doyub Kim's [fluid-engine-dev](https://github.com/doyubkim/fluid-engine-dev). It's built on C++11 and compiled with Microsoft Visual Studio 2017. This fluid engine is just for personal learning and interest.
## Features
- Basic math and geometry operations and data structures
- Jacobi, Gauss-Seidel, SOR, MG, CG, ICCG, and MGPCG linear system solvers
- Spherical, SPH, Zhu & Bridson, and Anisotropic kernel for points-to-surface converter
- Intel TBB multi-threading backends
- SPH and PCISPH fluid simulators
- Converters between signed distance function and triangular mesh
- Stable fluids-based smoke simulator (Pure Euler fluid solver)
- Level set-based liquid simulator
- Fluid solvers have both 2-D and 3-D version
## Start
Just clone the code and open it with Microsoft Visual Studio 2017. There are three vs2017 projects. **FluidEngine** is the core of engine. **Test** is for unit test while **FluidExample** includes several fluid demos.
## Todo
- PIC, FLIP, and APIC fluid simulators
- Position based fluid simulator
- Visualizer based on OpenGL
- Flame simulator
- GPU version of SPH Simulator
- ......
## Learning Notes(In Chinese)
These are not documentations for the engine but simulation algorithm notes.

## Example
The engine is just for simulation and can use some renderers (such as [Mitsuba renderer](https://www.mitsuba-renderer.org/)) to render it for visualization.
