Smoke/Fire Simulation

Implemented a 3D Semi-Lagrangian smoke fluid simulation using the Navier-Stokes equations and a marker-and-cell (MAC) grid in C and rendered in real-time using OpenGL. Velocity, density, and temperature are advected onto the smoke particles and buoyancy and vorticity confinement external forces are applied on the system. Incompressibility is maintained by doing a pressure solve using a conjugate gradient solver and then projecting it onto the system.
