In the field of computer graphics, fluid-like motion is an important and challenging problem with many applications. Currently, the graphical performance and resolution of the mobile handset is highly improved; therefore, mobile 3D games and physically based animations are also more and more popular items in the mobile services. Yet interactive physically-based fluid simulation is still challenging for mobile games. We studied and implemented physically-based models based on Navier-Stokes equation for fire and smoke effects on mobile 3D games. To make an efficient fire effects on mobile games, we implemented billboard based 2D fluid simulation and gradient based coloring effects. We also implemented external forces on billboard for interactive fire simulation with game characters. The mobile platform of our system is WIPI, which is the standard mobile platform in Korea and NF3D for our 3D programming API. All the simulations have also been adopted for our mobile 3D game, “Rupee Story”.
