Computer Animation with Real-World Lighting (in inglese)
Paul Debevec
 
The quest for realism in computer graphics has frequently benefited from injections of reality: real-world textures from digital photography, real-world geometry from 3D scanning, and real-world movement from motion capture. In this talk I will discuss the ICT Graphics Lab’s work in bringing real-world lighting into computer graphics: using high dynamic range photography for capturing light from the real world, adapting global illumination to illuminate computer-generated objects with real-world light, and building devices for reprojecting captured illumination onto real objects and people. The results are that virtual objects can be realistically rendered into real scenes, computer-generated environments can be illuminated with natural lighting, and actors filmed in a studio can be realistically rendered into photoreal virtual sets. I will illustrate the techniques with computer animations, cultural heritage projects, and clips from recent feature films.
