水稻稻穗三维形态交互设计及可视化仿真研究

3D Interactive Design and Visualization of Rice Panicle

根据水稻稻穗的三维形态结构特征,分析稻穗的拓扑结构并进行参数化建模,实现水稻稻穗的交互设计及可视化仿真。首先,建立稻穗的几何模型,用B样条拟合的方法生成水稻的谷粒,用球B样条生成稻穗主轴、枝梗轴和小枝梗;在稻穗几何模型的基础上,基于OpenGL图形库,应用光照和纹理映射等渲染技术增强了真实感,实现了稻穗的三维可视化。实验结果表明,可视化模型具有良好的可控性和较高的真实感效果。

According to morphological structure of rice panicle,3D interactive design as well as visualization of rice panicle is implemented based on the topological analysis and parameterization.Firstly,B-spline curves are used to construct the rice grain model.Ball B-spline objects are used to construct the rice panicle main axle and primary and secondary branch axle.And then,lighting and texture mapping are used to render the realistic scene based on OpenGL graphic library.The experimental results show that the visualization model has highly controllability and realistic effect.
