Computing global illumination in a moderate time for complex environments and walking through them is one of the challenges in computer graphics. To meet this goal, a prepro-cessing is necessary. This preprocessing consists in partitioning the environment into cells and determining visibility between these cells. Most of the existing partitioning methods rely on the Binary Space Partitioning te...
