Abstract: Aiming at the problem that it can not accurately simulate the geometric characteristics of the rice leaf in virtual rice modeling and visualization, from the aspect of physics, this paper proposes a rice leaf mathematic model based on experimental data. It combines VC++ with OpenGL, vectorization and virtual plant of leaf morph and its changing process can be realized by several morphological parameters with explicit biological meaning. Results show that this model can get good effects with less parameters, easier control, and it can simulate the growing process of rice leaf well.

摘要： 针对虚拟水稻建模与可视化中水稻叶片几何特征不能准确模拟的问题，从物理学角度出发提出一种基于实测数据构建的水稻叶片数学模型。该模型利用VC++与OpenGL相结合的方法，通过具有较明确生物学意义的形态参数，实现水稻叶片形态和形变过程的矢量化和虚拟生长。结果证明该模型效果好、参数少、易于控制，且可以较好地模拟水稻叶片的生成过程。
