Abstract: Grass is one of the nature elements that is difficult to simulate in real-time due to its large number and wide covering range. In view of the deficiencies of existing methods, a method for simulation of treading on grass was proposed. Constructed largcscale static grassland based on hybrid representation. Computed the deformation of grass close to the viewer by using GPU-based real time collision detection algorithm and force vector diffusion mechanism. Simulated the deformation of tussock by adjust the slope of billboard. In order to avoid popping between different levels, a transition scheme was implemented. Experiments show that this method not only can realistically simulate the effect of treading on grass,but also can overcome the deficiencies of the traditional methods.
Key words: Dynamic simulation, Grassland scene, Billboard, Level of detail
