In the field of computer graphics, applications such as movies and games benefit from realistic visualizations of fluid phenomena. Many methods have been proposed to simulate fluids behavior such as smoke, clouds, water and flames. However, in the field of CG, the magnetohydrodynamics that underlie the interaction between fluids and magnetic fields have not been extensively studied so far.
The phenomena covered by electromagnetic hydrodynamics can be further classified into plasma and magnetic fluids. The dynamics of aurora and prominence in the sun can be calculated by simulating a plasma. Meanwhile, magnetic fluids behave as both fluids and as magnetic bodies, and these characteristics allow them to generate ‘spike-like’ shapes along the direction of the magnetic field. It is important to represent and visualize these three phenomena using CG because these three phenomena are primary visual phenomena arising from the magnetic fields.
The goal of this research is to simulate two natural phenomena, the activity on the solar photosphere and aurora governed by magnetohydrodynamics equations, and the physical phenomenon of a magnetic fluid in the CG settings.
