Frequency-Space Decomposition and Acquisition of Light Transport under Spatially Varying Illumination
Published on Nov 12, 20123014 Views
We show that, under spatially varying illumination, the light transport of diffuse scenes can be decomposed into direct, near-range (subsurface scattering and local inter-reflections) and far-range t
