Physically-based Simulation of Plant Organs for Real-time Deformation

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.
