....reflection distribution function (BRDF) of different materials by, e.g. Cabral [3] and Westin et al. 29] Koenderink and van Doorn [17] proposed replacing the spherical harmonics basis with the Zernike polynomials, since BRDFs are defined over a half sphere. Nimeroff et al. 23] Dobashi et al. [5] and Teo et al. 26] explore specific lighting configurations that can be represented efficiently as a linear combination of basis lightings (e.g. daylight) Dobashi et al. 5] in particular use spherical harmonics to form such a basis. D Zmura [6] was first to point out that the process of ....

D Zmura [6] was first to point out that the process of turning incoming light into reflection can be described in terms of spherical harmonics. With this representation, after truncating high order components, the reflection process can ....

....often tremendously complicated, and in such cases these techniques are not fast enough to permit the interactive modification of lighting specifications. A recently developed alternative approach is to re render the images as linear combinations of a fixed set of previously rendered basis images [8, 17, 6, 7]. The validity of this approach rests on a fundamental property of graphical rendering: linearity with respect to light source intensities [3, 12] Specifically, rendering obeys the principle of superposition: 1) multiplying the intensity of the light source by an arbitrary factor scales the ....

....rotation invariant subspace of light sources. In particular, Nimeroff et al. 17] use a set of steerable area lights on a hemisphere, designed to approximate the illumination effects of daylight. The steerability property allows the representation of a continuum of sun positions. Dobashi et al. [6] use basis lights spanning the space of directional spot light sources, each positioned at the same location but aimed in different directions. A spherical harmonic decomposition was used to ensure rotation invariance. In this paper, we extend the re rendering approach to lighting design. We ....
