摘要：

This paper proposes a strict ray-based shadowing rule to compute the visibility between two facets in the iterative physical optics (IPO) method. This computation is further accelerated through the kd-tree structure to reduce the number of intersection tests between a ray and facets. Compared with previous IPO with a simplified shadowing rule, the proposed method is more efficient, accurate, and stable.
