Visual Simulation of the Interaction Between Spray Droplets and Plant Canopy
Spraying pesticides for crops is a common phenomenon in the management process of crop planting, and a key factor influencing the development of plants and plant ecosystems. An effective method is therefore proposed to visually simulate the interaction between spraying droplets and a plant canopy. In this method, a model to describe spraying droplets was first built and then the spraying scene was simulated by using the technique of Particle Systems. The smoothed particle hydrodynamic (SPH) method was employed to simulate the physical laws of the spraying. The plant model was discretized to a skeleton with control points and the deformation of the plant under the influence of the spraying droplets was simulated. The experimental results showed that the proposed method can simulate this deformation.
