Fast Geometric Simulation of Ground Surface with GPU

Abstract

In this paper, we propose a new method for geometrically simulating a surface ground by the rotary grinding machine. In our method, a grinding operation with a single particle is considered as a milling operation with a very thin ball-end cutter. Geometric milling simulation technology is thus applied to visualize the ground surface realized by many grinding particles. In order to accelerate the computation, the depth buffer mechanism of GPU is used. An experimental simulation system is implemented and its performance is demonstrated. The system can visualize the ground surface with more than 2500 particles in 10 seconds.
