Fruit Ring Rot Simulation Based on Reaction-diffusion Model
Simulating the process of fruit disease using computer techniques can help make effective prevention and establish corresponding treatment.Aging and blemish in fruits’ appearance can also enhance the realism of a synthetic scene,with wide applications in virtual reality,games,and special effects.However,little attention has been paid in such field.This paper proposed a novel method for simulation of fruit ring rot process,which is one of the main diseases of fruits.An improved reaction diffusion model was adopted to model the colony formation.This model enables simulating the growth and movement of fruit ring rot accurately,accounting for different properties of different fruits including ambient temperature,humidity,skin thickness and porosity,etc.The initial nutrient parameters can be friendly designed according to ring rot characteristics.The software of Maya is utilized for fruit modeling and disease area rendering.Various results show that our method can produce the similar fruit ring rot symptom to the real data,providing technical supports for teaching,scientific research as well as promotion of agricultural science and technology.
