The method proposed in the article adds the possibility of rendering fuzzy reflections to the existing ray tracing systems. It is based on the idea of special blurring. Depending on the roughness of the reflecting surface, the specular component of the image is blurred. Even such special filtering does not require much time, besides it can be optimized to concrete processor architecture. Even implementation of the method in C++ (without any assembly code) results only in 2 % decrease in rendering speed.
