AbstractWe address the problem of relighting of three-dimensional scenes and propose a new method based on reconstruction of light transport matrix. The matrix can be reconstructed on-fly from data obtained by some renderer (we use path-tracing algorithm). We compared our method with existing ones. The proposed method achieves better quality compared to others with the same compression ratio. It is suitable not only for diffuse scenes and can be easily parallelized. In future we can use this method as a new global illumination algorithm.
