Fluid Engine Dev - Jet
Jet framework is a fluid simulation engine SDK for computer graphics applications that was created by Doyub Kim as part of the book, "Fluid Engine Development". The code is built on C++11 and can be compiled with most of the commonly available compilers such as g++, clang++, or Microsoft Visual Studio. Jet currently supports macOS (10.10 or later), Ubuntu (14.04 or later), and Windows (Visual Studio 2015 or later). Other untested platforms that support C++11 also should be able to build Jet. The framework also provides Python API for faster prototyping.
The latest code is always available from the main branch. Since the code evolves over time, the latest from the main branch could be somewhat different from the code in the book. To find the version that is consistent with the book, check out the branch book-1st-edition.
Key Features
- Basic math and geometry operations and data structures
- Spatial query accelerators
- SPH and PCISPH fluid simulators
- Stable fluids-based smoke simulator
- Level set-based liquid simulator
- PIC, FLIP, and APIC fluid simulators
- Upwind, ENO, and FMM level set solvers
- Jacobi, Gauss-Seidel, SOR, MG, CG, ICCG, and MGPCG linear system solvers
- Spherical, SPH, Zhu & Bridson, and Anisotropic kernel for points-to-surface converter
- Converters between signed distance function and triangular mesh
- C++ and Python API
- Intel TBB, OpenMP, and C++11 multi-threading backends
Every simulator has both 2-D and 3-D implementations.
Quick Start
You will need CMake to build the code. If you're using Windows, you need Visual Studio 2015 or 2017 in addition to CMake.
First, clone the code:
git clone https://github.com/doyubkim/fluid-engine-dev.git --recursive
cd fluid-engine-dev
Python API
Build and install the package by running
pip install -U .
Now run some examples, such as:
python src/examples/python_examples/smoke_example01.py
C++ API
For macOS or Linux:
mkdir build && cd build && cmake .. && make
For Windows:
mkdir build
cd build
cmake .. -G"Visual Studio 14 2015 Win64"
MSBuild jet.sln /p:Configuration=Release
Now run some examples, such as:
bin/hybrid_liquid_sim
Docker
docker pull doyubkim/fluid-engine-dev:latest
Now run some examples, such as:
docker run -it doyubkim/fluid-engine-dev
[inside docker container]
/app/build/bin/hybrid_liquid_sim
