| 摘 要： | 通过对玉米根系形态建成过程根系的结构、生长及分布特点和规律观测研究,构建了描述玉米根系形态变化的数学模型。结合粒子系统和计算机图形学技术,在计算机上实现了玉米根系生长的三维显示。其结果和实际的玉米根系的生长发育过程基本一致,为农学研究者提供了一个可视化的根系模型。本模型结构简单、可交互、真实感强,可以较好地虚拟玉米根系的生长过程。 |

| Abstract: | Through close observations and researches on the rules and characters of the structure, growth, distribution of corn root system in the growth process, the growth model that describes roots growth process was set up. Based on the parameters of time and shape offered by the growth model, the mathematic model for changes on shapes in root system of corn was brought forward. By the meanings of techniques of Computer Graphics and Particle System, the 3-Dimension Visualization of leaf growth process was realized on computers. The result can basically reflect the rules of real corn root system during growing. The advantages of the model are as the following: the structure is simple, it is apt to be mutual, the images produced at computer by the model has high Sense of reality, and it can simulate the growing process of the corn root system very well at computer. |
| Keywords: | computer application corn root system mathematics model particle system changes of shade 3-Dimension visualization |
