In this paper we extend our previous result on reusing shooting paths when dealing with moving light sources in radiosity to the final gathering step algorithm, which combines a shooting solution and a gathering step. Paths are reused for each frame in both shooting and gathering steps, obtaining a noticeable reduction of cost in the computation of the solutions for every frame. Moreover, the correlation between consecutive frames happens to be higher than in the case of independent solutions, resulting in a clear reduction of the temporal aliasing effects in the animation.
