Visual Simulation of Magnetic Fluid Taking into Account Dynamic Deformation in Spikes

In the physical field, several simulation methods for magnetic fluids had been proposed to analyze magnetic fluids' behavior. However, from their results, we estimate that it is difficult to simulate the spike shapes using only fully physically-based methods. Therefore in our previous work, we proposed the method which synthesizes the spike shapes by employing the procedural approach for visual simulation of magnetic fluids. Because the spike shape has been determined beforehand, this method has a drawback, that this method cannot simulate the dynamic arrangement and deformation of spikes. To overcome this drawback, we propose a simulation model based on the assumption that the spikes are attracted by an external magnetic field and each spike repels each other by the magnetization of itself. The coordinates of the conical undersurface centers of spikes on the liquid surface are determined in the simulation and the spike shape is mapped according to the direction of magnetic field lines.
