Hi,
I just want to confirm that whether the code at:-

http://code.google.com/p/structured-light/source/browse/#svn%2Ftrunk%2FOpenFrameworks%2Fapps%2FstructuredLight
(for both 'capture' ad 'decode' apps.)

is based on the paper :-

High Resolution real time 3D absolute coordinate measurement based on
phase shifting method-By:-Song zhang & Shing-Tung Yau

Actually i was trying to understand the underlying theory(for code)
and found it to be somewhat similar to that given in this paper,so i
just wanted to ensure that is it ok to refer to this paper to
understand the code.

capture and decode are based on a variety of papers. they're not structured very well, and i don't recommend using them as a reference.

however, FastThreePhase is fairly clean. it's based very directly on "Multilevel quality-guided phase unwrapping algorithm for real-time three-dimensional shape reconstruction" by Song Zhang, Xiaolin Li, and Shing-Tung Ya (2007).

it also contains some optimizations that i developed independently, but are similar to ones described in "Dual-frequency pattern scheme for high-speed 3-D shape measurement" by Kai Liu, Yongchang Wang, Daniel L. Lau, Qi Hao, and Laurence G. Hassebrook (2010).

the best way to understand theory of individual chunks of code s is to look at the commit log: https://code.google.com/p/structured-light/updates/list

hope that helps,
kyle
