“…Kawai et al 11 presented a system whereby a user could specify certain target luminous conditions and the optimal luminaire focussing and output would be generated. Schoeneman et al 12 allowed the user to "paint" lighting patterns on a rendered scene and then determined the light outputs and colours from a given set of fixed luminaires that would most closely match the desired pattern. One drawback of these automatic optimization techniques is that they are based on the user's pre-existing biases towards a desired solution and on pre-programmed weightings of various performance parameters, thus reducing the exploration of novel solutions.…”

“…A quintessential part of most of these systems is an intuitive interface to input the desired lighting results. Some rely on direct specification and manipulation of lighting-induced features like shadows or highlights [Poulin and Fournier 1992;Pellacini et al 2002], while others adopt a painting paradigm where the intended illumination result is painted by the user [Schoeneman et al 1993;Anrys and Dutré 2004;Okabe et al 2007;Shesh and Chen 2007]. Advanced examples are the system for cinematic lighting by Pellacini et al [2007] and the recent work by Lin et al [2013].…”

“…Our decomposition also bears resemblance to methods for precomputed radiance transfer, where a low dimensional representation of light transport is used to efficiently render interreflections under varying illumination [Hašan et al 2006]. Similar to our stroke-based interface, researchers have also developed rendering systems that adjust light source intensities [Schoeneman et al 1993] and light transport itself [Obert et al 2007] to match user-specified target illumination. Sparse gradient priors, like the one used by our system, have previously been used for image restoration.…”
