It is necessary to judge the lit region and the shadow region in the PO area when we use the MOM-PO hybrid method. This paper proposes a highly efficient method to complete this hidden face removal. First of all, it divides all the triangles in the geometric model into groups by the commonly-used Z-Buffer method, thus decreasing the time-expenditure. And then a strict method is adopted to find the lit triangles with high accuracy. Finally, we apply the domain decomposition method to decrease the memory requirement. A numerical experiment shows this new method can obtain a more accurate result than the Z-Buffer method by 18.6% at the expense of only a little more time and memory.

Key words: moment methods, physical optics, hidden face removal, domain decomposition methods
