The initial goal of this project was to create a physically accurate GPU-accelerated simulation of fire. Due to limited time available in the semester (combined with the inherent difficult of debugging CUDA code) we ended up reducing the scope somewhat and focusing on a realistic GPU-accelerated technique for rendering incandescent gas, as in flames, without doing a full fluid simulation. The application was written in C (GPU code) and C++ (CPU code) and tested on a laptop running 64-bit Linux with a GTX 460m card.
