3D modeling of bunch grass with simple blade based on multidimensional parameters

Grass modeling has been a high attention problem in computer graphics field for recent years. This paper builds the multidimensional parameters geometrical model of blade firstly, and then makes the random translation and rotation transformation for blades, finally, forms the concentric circles model of the grass. And to improve the render speed, we can clip of grass scene by using the relation between the vision boundary and the scene block in order to reduce the computation. The simulation experiment shows that, this method can make the grass scene more real and the interaction better.
