Toward Evaluating the Usefulness of Global Illumination for Novices in Lighting Design Tasks

Autor: Jaroslav Krivanek, Martin Ru̇z̆ic̆ka, Václav Gassenbauer, Ondrej Karlik, Fabio Pellacini

Thanks to its ability to improve the realism of computer-generated imagery, the use of global illumination has recently become widespread among digital lighting artists. It remains unclear, though, what impact it has on the lighting design workflows,
