Abstract

Abstract: To explore the evolution process of rice leaf cell morphology with the help of computer visualization technology, it is necessary to establish the biomechanical relationship between the cell geometry model and its deformation. A dynamic simulation method is proposed for the 3D visualization of leaf cells based on the physical-mechanical properties, in which the cytoskeleton topology is represented by a "half-edge" data structure, and the surface geometries are constructed using a bicubic Bézier surface. The control parameters of a deformed surface are determined through "vertex", "edge" or "face" topological unit query algorithms of the cytoskeleton, and the cell stress-strain values are evaluated with the help of the Cauchy stress and the Generalized Hooke's law. The experiment environment is implemented using C++ programming and OpenGL graphics library. The results show that the use of different values of osmotic pressure difference and elastic modulus can obtain the free deformation of the surface and thus the dynamic simulation process of the three-dimensional visualization model of the cell. The method helps to introduce an information technology to study leaf morphogenesis from the perspective of cell mechanics.
