Physically-Based Algorithm for Natural Rime Growth Simulation

In order to show a common natural landscape in winter, the charm of rime, an algorithm for rime growth simulation based on a physical approach is proposed in this paper. This algorithm mainly simulates two main kinds of rimes' growth, especially their morphology and direction, under the condition of surrounding factors, including the air pressure, temperature and wind. Firstly, this algorithm calculates the length of rime by using the icing conductor model which is established according to fluid mechanics and thermodynamic principles, a fractal method is introduced into our algorithm to simulate the morphology of the crystalline rime, and a segmentation method is for the simulation of the needle-like rime's morphology; After that, wind field is simulated by adopting the function of Perlin Noise. Finally, it analyzes the offset details of the rime growth in the wind according to its material mechanics knowledge. The wind force is used to calculate the deviation of rime. Experimental results show us that our algorithm in this paper can simulate two kinds of rime realistically, effectively and efficiently.
