Lecture 13: Global Illumination and Path Tracing (69)

Are there instances in computer graphics where we need to consider how the light rays destructively interfere with each other and result in loss of contribution by specific rays? The example here depicts multiple rays converging on a single surface and it seems that they are constructively interfering.


I think for this class we are taking the assumption that light rays don't interfere with each other. Theres a lot of interesting projects and papers regarding studying this in situations such as when dealing with thin films.


This was mentioned in Radiometry/Photometry where we assume no interference between lights, i.e. ignore their wavelike properties.
