摘要 近年来,各种方法被用来模拟可变形物体的实时变形。提出了一种基于质点-弹簧系统的植物器官变形模拟方法,并根据交互式设计的要求开发了参数化的植物器官几何造型和弹簧模型生成方法,简化了质点-弹簧模型的构造。实验结果表明,该方法能够获得具有较高真实感的变形效果,能够适用于多种植物器官一般情况下的变形模拟;同时,参数化的几何曲面和物理模型生成能够满足于交互式实时模拟的需要。 In recent years, a variety of methods has been proposed for real-time simulation of deformable solids. A method for modeling the deformation of plant organs was proposed based on mss-spring system, and the parameterized methods for generating the 3D geometry and the spring model of plant organs were developed to satisfy the needs from interactive design. This could simplify the creation of mass-spring model Results on several plant organs demonstrate that the proposed approach is applicable for simulating deformation of plant organs with realistic effects. Furthermore, the parameterized generation of geometric surface and physical model can be used in interactive simulation at real-time speed.
