6.3. Image-Based Relighting

The image-based lighting techniques we have seen so far are useful for lighting synthetic objects, lighting synthetic environments, and rendering synthetic objects into real-world scenes with consistent lighting. However, we have not yet seen techniques for creating renderings of real-world objects illuminated by captured illumination. Of particular interest would be to illuminate people with these techniques, since most images created for film and television involve people in some way. Certainly, if it were possible to create a very realistic computer model of a person, then this model could be illuminated using the image-based lighting techniques already presented. However, since creating photoreal models of people ...
