Researchers commonly apply IBMR techniques
to environments or scenery. For example, with
“Inverse Global Illumination: Recovering
Reflectance Models of Real Scenes
from Photographs,”4 the authors presented
a technique that uses imagebased
rendering to construct
estimates of radiance and directional
irradiance for small patches of the
model. These estimates are then used
to create high-resolutionillumination
maps. The technique develops a
lighting-independent model of the
scene that can be re-rendered under
differing light conditions and
includes newly introduced digital
elements. The film and television
visual effects industry as well as
architectural space planners could
benefit greatly from such techniques.
