About this video

This is a demo of a hydraulic jump simulation with FluidX3D, running on a single Nvidia Titan Xp GPU, which lacks RTX. The grid resolution is 96x352x96 (3.2 Million) cells. Both simulation and raytracing run in real time. The simulation software used is FluidX3D, the fastest and most memory efficient lattice Boltzmann CFD software, running on all GPUs via OpenCL. Find FluidX3D on GitHub: https://github.com/ProjectPhysX/FluidX3D The latest update FluidX3D v2.5 featured in this demo adds light attenuation in the fluid and improved raytracing performance when the camera is inside the fluid.
