light field[edit]

The light field is a very general concept. As it stands, this article is too computer-graphics centric, and within computer graphics it is too Stanford-centric. Others are encouraged to expand and broaden it. -User:MarcLevoy

On the proposal to merge Light Field and Light field camera: This does not seem like a good idea. While the light field camera (although the author calls it a Plenoptic camera, which also has a page - so that should be merged with Light field camera) is the most visible result so far with the word 'light field' in it, it is only one application, and many other research results exist. 171.67.73.10 20:47, 23 February 2007 (UTC)[reply]

Light field camera and Plenoptic camera have since been merged. -- Beland (talk) 00:46, 8 December 2011 (UTC)[reply]

5 / 7 / 8 dimensional plenoptic function?[edit]

Having a look at this article where the plenoptic function is listed as 5 dimensional (3 space, 2 direction) with two possible additional dimensions (1 wave length, 1 polarization) and having a look at the article Image-based modeling and rendering where the plenoptic function is declared having seven dimensions aswell but instead of ploarization listing time, would this not lead to a eight dimensional function in total having 3 space, 2 direction, 1 wave length, 1 polarization and 1 time which should be mentioned for in both articles for consitency?

Fixed. -- Beland (talk) 00:48, 8 December 2011 (UTC)[reply]

Light Field Distinction[edit]

I suggest that we clearly separate Gershun's light field (vector irradiance field), from the plenoptic light field (radiance). Currently, the 4D and 5D representations of plenoptic light fields have separate sections while Gershun's light field is mentioned here and there throughout the article. I think that Gershun's light field deserves its own section, which would also give a container for the figures of his work. ClaudeKnaus (talk) 15:41, 21 September 2010 (UTC)[reply]

Reference missing to Da Vinci principles[edit]

Leonardo Da Vinci is the author also of some interesting plenoptic and light field ideas (much before Faraday), like the "radiant pyramid", as quoted in this famous sentence:

"Every body in the light and the shade fills the surrounding air with infinite images of itself; and these, by infinite pyramids diffused in the air, represent this body throughout space and on every side."

Reference:

Leonardo and I. Richte, "The Notebooks of Leonardo Da Vinci", Oxford University Press, 1980.

May be this could be added in the page. —Preceding unsigned comment added by 85.201.210.204 (talk) 09:12, 11 December 2010 (UTC)[reply]

Potential Plagiarism?[edit]

The portion on the 4D light field appears to be taken from this work: http://graphics.stanford.edu/papers/lfphoto/levoy-lfphoto-ieee06.pdf, including several images. This may however be a mistake or a misunderstanding on my part as severall of the other portions appear to appropriately cite different articles by the same author. — Preceding unsigned comment added by 159.233.97.181 (talk) 19:39, 7 October 2014 (UTC)[reply]

Footnotes[edit]

I note that the parenthesized in-line references do not link to the references below. The norm (not the standard) in WP is to use numbered notes that link to references. I would be happy to convert the article if there are no objections... Lfstevens (talk) 19:49, 25 October 2014 (UTC)[reply]

What's with the "Last name (year)" tags all over the article?[edit]

I find them SUPER annoying. It seems like someone thought these were substitutes for inline citations or something. What gives? --uKER (talk) 21:10, 27 July 2016 (UTC)[reply]

It's an inline citation scheme called 'parenthetical referencing' (see WP:PAREN) that has been used for thousands of articles. Ideally, the citations would be linked to the references. David Koller (talk) 22:18, 27 July 2016 (UTC)[reply]
Damn, I had never seen it anywhere else here on Wikipedia and it really puts me off. Thanks for the explanation though. --uKER (talk) 19:46, 28 July 2016 (UTC)[reply]
