基于自由曲面和L-system的红掌生长模型
The anthurium growth model based on free-form surface and L-system
摘要
Abstract
Aiming at the difficulty of determining the parameters in visualization of anthurium flower growth,a method for deducing control points was proposed to establish anthurium organ model in this study using Bezier curve combined with scanning molding for the leaf stalk model and bicubic NURBS curve for the flame bud model.The differential L-system based on the growth law of anthurium was proposed to simulate the topological structure and growth process of anthurium effectively by fitting the growth function with the related phenotype data of anthurium.The geometric properties of anthurium organs were represented by virtual organs to reduce the complexity of differential L-system.The experiment verified that the fitting degree of the proposed method for the growth indicators of anthurium were higher than 0.89,and it was able to simulate the growth of anthurium at each growth stage,effectively modeling the whole growth process of anthurium.关键词
