Real Time Fire Visualization Using Computational Fluid Dynamics.

As my final project for CMPS 161, I implemented a real time CFD system using the technique described in Jos Stam’s paper, "Real-Time Fluid Dynamics for Games". I modified their original code to take temperature and gravity such that hot air will rise and cool air will fall as expected in real life.

• Left Mouse Button: Creates wind in the positive direction;


• Right Mouse Button: Creates wind in the negative direction;


• Middle Mouse Button: Creates a new combustion point;


• Escape Key: Reset simulation;


• S Key: Toggle smoke particles;


• V Key: Toggle Velocity Lines;


• P Key: Toggle Velocity Particles (To better view airflow);


• T Key: Toggle Smoke Texture;


• C Key: Toggle Solid / Open Roof/Floor of Simulation;

The box/wedge can be moved with any mouse button. It can also be reshaped by clicking and dragging on any corner.

Here is a short movie of the program in action:
