摘　　要：为构建辣椒植株可视化模型,借助三维数字化仪获取了辣椒枝干、叶片和果实的真三维数据,结合球B样条曲线模拟了枝干的三维形态,利用NURBS曲面和T样条拼接方法建立了辣椒果实几何模型,描述节、果实的凹凸、顶端叶序等局部特征,在各器官的自动着生过程中,避免器官间的碰撞。模拟结果表明,该方法得到的模型较真实地反映了辣椒的诸多细节,具有较高的真实感,为辣椒三维形态交互设计和可视化模拟提供了技术支撑。To provide an efficient method for 3D geometric morphological modeling and visualization of pepper, based on the analysis and observation of the morphological structure of pepper, the 3D data of limbs, leaves and fruits are obtained by three dimensional digitizer. Ball B-splines based method is used for modeling the shape of pepper limbs, with the use of NURBS sur- face and T^spline to model the peppers fruits. The proposed methods for modeling the 3D shape of organs and simulating pepper is integrated easily with agricultural knowledge, and the generated morphological models have realistic effects. The flexibility and suitability of the proposed methods is applied to the visual simulation of the different varieties of pepper.
