Abstract:
Lighting is a very important component of 3D environment design. Research efforts in perception, neuroscience, animation, and film have shown the importance of visual design (a term used to denote lighting, camera motion, and staging design) in guiding participant’s attention to important elements in a scene [Block 2001, Bollmann et al. 1997, Calahan 1996, Navalpakkam and Itti 2002, and Treisman et al. 1980]. Neuroscience and psychophysics literature identified several visual attention features: contrast, eccentricity, symmetry, and motion [Treisman et al. 1980, Navalpakkam and Itti 2002].
Cinematic and theatric lighting designers continuously modulate scene lighting to accommodate several design goals, including direct audiences’ attention towards important areas in a scene, establishing visibility, evoking moods, and setting atmosphere [Block 2001]. A similar method for controlling and modulating lighting is required for interactive 3D environments. Currently most games use static set-based lighting approach, which does not accommodate the dynamic and unpredictable nature of interactive environments.
