The light field
•Known as the plenoptic function
•If you know R, you can predict how the scene would appear from any viewpoint.
How?
The light field
•Assume
radiance does not change along a ray
–what does
this assume about the world?
•Parameterize
rays by intersection with two planes:
•Usually drop l
and time parameters
•How could you
capture a light field?
t is not time (different from above t !)
