Experimenting with performance evaluation and improvements to Brandon Pelfrey's smoothed-particle hydrodynamics (SPH) fluid simulation tutorial:
- Real-time Physics 101: Let’s Talk Particles
- Real-time Physics 102: Springboard into Constraints
- Real-Time Physics 103: Fluid Simulation in Games
- CMake >= 3.7.2
- C++11 compiler
- OpenGL support
- OpenMP support
- Q/Escape: Exit
- Space: Add more particles
- Mouse button: Attract nearby particles
- +/-: Increase/decrease the number of simulation steps per frame
You can use the OMP_NUM_THREADS environment variable to limit the number of threads used by OpenMP.
Appropriate versions of GLFW and GLM are included as submodules so you should be able to clone and build without anything more than CMake and a compiler:
git clone https://github.com/genpfault/sph-tutorial.git
cd sph-tutorial
git submodule update --init --recursive
mkdir build
cd build
cmake ../ -DCMAKE_BUILD_TYPE=RelWithDebInfo
cmake --build .
