Biologically and Physically-Based Rendering of Natural Scenes - Baranoski (1998) (Correct)
....models and the rendering algorithms that include estimates of indirect illumination are usually called global illumination models [86] Although these two terms local and global describe the extremes of a continuum, one can not overlook the interplay between them. As pointed out by Fournier [76], the only way the light acts at the rendering level is locally, through intricate phenomena, such as reflection, transmission and absorption of the incident light, which are physically represented by reflectance and transmittance models (discussed further in Section 2.6) In addition, considering ....
....discrepancies may be due in part to the fact that we did not consider the carotenoids (which account for 20 of the total amount of pigments) and that we did not separate different chlorophyll pigments. Moreover, the underestimation of surface microdetails, and shadowing and masking effects [76] may also contribute. Nevertheless, it shall be noted that the curves presented in Figure 4.5 represent mainly qualitative comparisons between modeled and measured values, since some parameters used in the simulation, such as the refractive indexes and the oblateness, correspond to average values ....

The Light Volume: an aid to rendering complex environments - Chiu, Zimmerman, Shirley (1996) (1 citation) (Correct)
....the non diffuse case [3] The basic problem with these methods is that they take to much storage to represent a solution with sufficient spatial and directional accuracy. This problem has been addressed by making a coarse solution and then gathering from it [16, 3] Fournier and his collaborators [4] have promoted a divide and conquer strategy. They have observed that if you know the all the light that crosses the surface of an imaginary volume enclosing a part of the scene, then the volume can be closed off as long as no new light enters the volume. If new light does enter the volume, then ....
....main memory, however, so some kind of information condensation must be used. We also think some kind of importance or bidirectional approach is needed. Veach [17] has made it clear that sometimes working from the light source is good, and sometimes working from the view point is good. Fournier s [4] insight into how geometry and radiance can be interchanged might provide a way to utilize Rushmeier s geometric simplification ideas. We have also found that comparing methods is difficult without a standard set of scenes. We would like to see the graphics community agree upon a standard database ....

Wavelet Radiative Transport and Surface Interaction - Lewis, Fournier (1996) Self-citation (Fournier) (Correct)
....illumination describes how light is distributed in a scene: a collection of objects, including light sources, immersed in a given medium. Global illumination solutions must consider multiple reflections. Global illumination solutions are built on top of local illumination solutions. Fournier [6] describes their interrelation further. In this paper, we will advance a new approach to an illumination solution that is intermediate between local and global illumination. Using wavelets, we are able to treat the interaction between two surfaces and the interaction of a surface with a radiation ....
