Talk:Projective transformation

From Wikipedia, the free encyclopedia

This article is too big, at the present state it is not at all an encyclopedia article, it is just a piece of a textbook. I think it should be moved to corresponding wiki-book project and here only minimal set of facts should stay. It should not contain proofs, infact I do not think these proofs are interesting enough to be here, but it is ok for a text-book. Tosha 06:52, 15 Apr 2004 (UTC)

I agree. This is...a bit much. The explicit calculations are distracting from getting an overall view. (Anon.)

There is already a place for discussing Moebius transformations and cross-ratio. I suppose some people might prefer the direct computational proof of invariance of cross-ratio; not to my taste. So I think some at least of the projective line material could be moved elsewhere.

Also, the transformation of conics is done in nineteenth-century style. I'm sure there is a better way of expressing it.

If there's no objection, I may try to move some of the proofs over to "proof pages", analogous to others on Category:Article proofs. This should make the page easier to read and quicker to load, without loosing content. linas 03:43, 27 June 2006 (UTC)
