| 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. |
