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 the feasibility of using Java3D to visualize the virtual plant, a mathematical model of rice main stem organs was proposed based on the study of rice. Based on this model, a three-dimensional model based on organ morphological parameters was constructed by Java3D programming. Taking into account the specific shape of the natural model, the relevant simplification. First, the leaf vein pulse curve was simulated based on the quadratic equation y = ax ~ 2 + x, then the leaf blade was simulated based on the sinusoid curve. The rice ear grain was simulated by the conic model. Simulation. The results showed that using Java3D to visualize the individual three-dimensional morphology of rice stem-leaf-panicle, which laid a solid technical foundation for the construction of rice visualization growth model.
