摘　　要：为了探究利用Java3D进行虚拟植物可视化的可行性,本文以水稻为研究对象,提出水稻主茎器官的可视化数学模型,在此模型基础之上,利用Java3D编程构建基于器官形态特征参数的三维空间模型。考虑到具体模型的自然形状,进行了相关简化。首先基于一元二次方程y=ax^2+x模拟叶片的叶脉曲线,然后叶片则基于正弦曲线进行模拟,稻穗粒采用圆锥型进行简化模拟,稻穗杆和茎杆均用圆截面柱体进行模拟。结果表明:利用Java3D可以实现对水稻茎杆-叶片-稻穗的个体三维形态的可视化,从而为构建水稻可视化生长模型奠定了一定的技术基础。In order to explore Java3D conduct virtual plant feasibility, taking rice as the study object, this thesis presents a visual mathematical model of main stern organ of rice. With Java 3D programming of morphological characteristics of organs, a 3D space model is established. Meanwhile, considering the specific natural shapes, the model is simplified. First, quadratic equations are used to simulate the main vein image of leaves and sine curves are used to leaves, cone angles are used to grains, then, circular cross-sections are used to grape plant. Thus, a 3D visualization of stem-leaf-grain is presented. The results show that these figures lay a foundation of a further development of visual growth system of wheat plant.
