The invention relates to a force-based plant and snow interaction simulation method, which utilizes a particle system to simulate a snowfall scene, is combined with a collision detection method to judge accumulated snow, is combined with the collision detection method to calculate an accumulated snow amount and utilizes the calculated accumulated snow amount to calculate a cut load of a branch soas to simulate the deformation of the branch. The method is combined with related knowledge of material mechanics, takes certain authenticity into account while guaranteeing efficiency, can be appliedto realistic simulation of the plants in a snowfall scene, and provides certain reference for simulation of the plants under snow, so that the virtual nominal in the snow better conforms to the realsituation. 一种基于力的植物与雪交互模拟方法，利用粒子系统模拟降雪场景，并结合碰撞检测方法进行积雪的判断，结合碰撞检测方法进行积雪量的计算并利用计算出的积雪量计算枝条的截荷以模拟枝条的形变。本发明结合了材料力学的相关知识，保证效率的同时兼顾了一定的真实性，可以应用于降雪场景中植物的真实感模拟，为积雪下植物的模拟提供一定的参考，使雪中的虚拟标称更符合真实的情况。
