Research on the Model Construction of Soybean Root System Based on L–System

摘要

Soybean root is one of the most important organs of soybean. It takes important effect on the growth and development, physiological function and metabolism of the soybean. Because of the particularity of the root growth environment, it makes the study of root crops far lagging behind that on the ground. Virtual plant overcomes the disadvantages of taking a long time on experiment and other environmental factors beyond our control. Hence, it is significant to study the root of the plant in visualization method. This article is completed by analyzing on the basic of root geometry, the author used logistic equation analyses of the experimental data collected, and get the growth of soybean root equation, according to soybean root the morphological structure characteristic of self-similarity, and discussed the virtual modeling method on the soybean root based on L-system and in visual c++ using OpenGL technology to achieve a soybean root system topology model.
