The paper presents an improvement of Monte-Carlo ray tracing which changes ray emission from a light source to accelerate convergence i.e. reduce the noise remained after the given run time. It is mainly intended for interior scenes illuminated from outside (e.g. skylight) through windows or other holes. The rays from light sources are generated so that they are directed to these windows. In other words, the number of rays is increased for directions that contribute to the camera image. It is shown that the proposed method allows calculating image with desirable quality several times faster.
