Real-Time 3D Fluid Simulation

Major project for BCIT Computer Systems Technology Bachelor of Technology (BCIT CST BTech).

A real-time fluid simulation and rendering demo, which implements the Smoothed Particle Hydrodynamics (SPH) algorithm using OpenGL compute shaders. The rendering section utilizes screen-space techniques, including fluid rendering, real-time shadows, and real-time caustics, and incorporates mouse dragging for interactive control.
