Abstract :
Traditional 3D visual simulation of flexible fishing net has the problems of complicated computation and no collision detection studied. In this paper, a 3D visual simulation method is researched in order to simulate the dynamic deformation of the flexible fishing net. To solve the computational inefficiency of the traditional mass-spring model, a simplified mass-spring model is presented. At the same time, collision detection algorithm is employed in the simulation. The dynamic model of fishing net is described as the mass point set which are linked by massless springs. According to Newton´s classic theory, the kinetics model of the mass points are established. Explicit Euler method is adopted to solve the mathematical model of the fishing net. Realtime 3D visual dynamic simulations for the deformation of various kinds of fishing net are conducted and the results verify the rationality of the method presented in this paper.
