Abstract: Aiming at the problem that visualization module of the selfdeveloped software AgriDEM (agricultural discrete element method) showed the vidio was not fluent  when the simulation data was huge, we proposed an accelerated visualization method of 3D discrete element software. From the point of view of display data reduction, the internal unit culling algorithm was used to simulate the visual depth of the human eye and occlusion feature of the object, and the data of the invisible particles in the object were removed. Thus, the load on the visual pipeline caused by the large data input was reduced, and 
the flicker and the vidio was not fluent problems of the simulation data visualization were solved.

Key words: data streamlining, internal unit rejection, discrete , element, visualization
