[edit] Category:Quadrics

All the images in this category are listed as being PD-ineligible, but they appear to be taken from CS3621 Introduction to Computing with Geometry Notes by Dr. C.-K. Shene. I beleive that the reason given because it consists entirely of information that is common property and contains no original authorship. is not valid. While the underlying mathematical equations are PD, there is original authorship in creating the images (colours, position, lighting etc). The date of files on Shene's page predates thouse on wikipedia. Full file hsitory on en was:

• I don't think there's any creative choice involved here (other than perhaps rotation). These appear to be the standard result of entering equations into rendering software. However I'm witholding my keep vote on this one because a) the software may be non-free and b) the shapes could easily be re-rendered using freely licensed software. -Nard the Bard 02:31, 11 September 2008 (UTC)
