Radiosity techniques produce highly realistic synthetic images for diffuse environments Monte Carlo random walk approaches, widely applied to radiosity, have as a drawback the necessity of a high number of random paths to obtain an acceptable result, involving a high computation cost The reuse of paths is a strategy to reduce this cost, allowing that a path distributes light power from several light positions, resulting in a noticeable speed-up factor. We present a new strategy of reuse of paths, which will allow us, given a previously computed set of radiosity solutions corresponding to n light positions, to add new light positions and accurately compute the radiosity solution at a reduced cost by reusing paths Our incremental strategy can be applied to light positioning in interior design, allowing the set of authorized light locations to be enriched by adding new positions chosen by the user.
