SPlisHSPlasH Fluid Simulation Code - Explore in 3D

SPlisHSPlasH stands as an open-source toolkit tailored for the physically-based fluid simulation. Embracing the Smoothed Particle Hydrodynamics (SPH) technique, a prevalent meshless Lagrangian methodology for modeling intricate fluid behaviors, the library facilitates efficient computation of fluid particle attributes through consideration of neighboring particles within a finite set. Among the forefront concerns in SPH methodologies is the replication of incompressible fluid behavior, a challenge met by SPlisHSPlasH through the integration of cutting-edge pressure solvers (WCSPH, PCISPH, PBF, IISPH, DFSPH, PF). Furthermore, the toolkit offers diverse strategies for simulating viscosity, surface tension, and vorticity, enhancing its versatility in fluid simulations. The code incorporates various external libraries, including Eigen, json, partio, zlib, cxxopts, tinyexpr, toojpeg, pybind, glfw, hapPLY, nfd, and imgui. These dependencies are all bundled within the package. Additionally, code utilizes custom libraries such as: (1) PositionBasedDynamics for dynamic rigid body simulation, (2) Discregrid for collision detection among rigid bodies, (3) CompactNSearch for neighborhood search functionality,(4) cuNSearch for GPU-accelerated neighborhood search, (5) GenericParameters for managing generic parameters. SPlisHSPlasH offers the capability to export particle data in both partio and vtk formats.
