Shifted sinusoidal illumination patterns are useful for appearance capture because they simultaneously separate local and non-local reflections and allow the recovery of surface g...

Previous studies have demonstrated that the appearance of an object under varying illumination conditions can be represented by a low-dimensional linear subspace. A set of basis i...

This paper presents a novel basis function, called spherical piecewise constant basis function (SPCBF), for precomputed radiance transfer. SPCBFs have several desirable properties:...
