The light transport matrix has become a powerful tool for scene relighting, owing to the versatility of its
representational power of various light transport phenomenon. We argue that scenes with an almost planar
surface geometry, even with significant amounts of surface roughness, have a banded structure in the light
transport matrix. In this paper, we propose a method that exploits this structure of the light transport matrix
and provide significant savings in terms of both acquisition time and computation time, while retaining a high
accuracy. We validate the proposed algorithm, by recovering the light transport of real objects that exhibit
multiple scattering and with rendered scenes exhibiting inter-reflections.
