Dynamic simulation of branch deformation under snow pressure

Abstract

Realistic simulation of dynamic interaction between plants and different natural environmental factors is a key topic in the field of natural landscape simulation. At present, few researches focus on the accumulation of snow on plants and the simulation of the dynamic deformation of a branch under the influence of the accumulation of snow. Therefore, we propose a simulation method for the dynamic interaction between snowfall and plants based on physical models. We first analyze the structure of the target plant and establish its physical structure model. Then we use the particle system and the plant branch collision detection method to calculate the amount of snow accumulation on the branches and generate the fluctuating snow grid surface based on the Berlin noise function. Finally, the cantilever beam model is used to calculate the deformation of branches under snow pressure. This modeling method proposed in this paper can provide a new research idea and technical reference for simulating the dynamic interaction between plants and environmental factors represented by snow.
