基于OpenGL和双三次贝塞尔曲面的稻叶可视化建模

近年来,虚拟作物的研究正逐步成为国内外数字农业研究的热点之一.叶片是水稻进行光合作用、营养物质生产与传输的主要器官,因此稻叶的精确模拟,对建立数字水稻模型具有重要的意义.利用系统分析方法和双三次贝塞尔曲面建模技术,首先分析不同时期水稻叶片的形状及参数,然后确定水稻叶片的控制点,通过控制点的空间坐标实现稻叶的卷曲,弯曲,扭曲,动态生长等,最后实现水稻叶片的可视化模拟.

The visual modeling of rice leaf based on OpenGL and bezier curved surface

In recent years,along with the development of computer simulation technology,virtual plant research is gradually becoming a hotspot in the domestic and foreign agriculture.As an organ of plant,leaf is crucial for the photosynthesis,nutrition production and transmission.And therefore the accurate simulation of rice leaf is very important for building digital rice model.Using the system analysis method and Bezier curved surface modeling technology,we analyze the shapes and parameters of rice leaf firstly.And ...
