Sammanfattning
Animation of fire and fluids has been around for at least 20 years in the field of computer graphics. These
animations have over the years progressed into real-time simulations running on the GPU and further refined,
thanks to modifications such as vorticity and wavelet turbulence, adding higher visual detail. With the
improving performance and capability of mobile phones, our issue was how well an animation of fire can be
achieved and under which limitations, when developed for a modern mobile device.
For our application, we used Java, C++ and GLSL. The simulation was built upon three layers: simulation
overview, simulation operations and slab operation. In order to simulate the behavior of a fluid, we chose to
use and compare the Euler equation and the Navier-Stokes equations. To optimize the performance of the fire
while still maintaining a high level of detail, we used wavelet turbulence.
The application was able to achieve our initial goal of reaching 30 frames per second with relatively good resulting
flame on a modern mobile device. However, older devices might not be able to achieve this performance
at all.
