| Outline of Final Research Achievements |
We proposed a new modeling method to simulate complicated deformations of aurora for CG animations. Although much research work has been done in order to reproduce the aurora phenomenon using 3D computer graphics, no one has recreated disconnection and reconnection of aurora, which are dynamic behaviors unique to aurora. In our method, the aurora distributions are represented as sampling points. The proposed method renders the CG animations of the aurora by projecting 3D aurora distribution to the screen and calculating the intensities of emissions.
Next, we propose a method for simulating glazed frost by computing heat transfers between water droplets and the surrounding air. We propose a method to create an animation of glazed frost formation by taking into account the heat transfer between particles and the outside grids. We propose a technique which is highly compatible for a FLIP method to solve the heat conduction equation and we reproduce the formation of glazed frost.
