Incorrect Formula? edit
I found this article to be quite useful while doing some coordinate frame transformations, however, it appears to me that the formula for the center of the circle should be (-da, -db, -dc.) I did not derive this; while writing unit tests for the software that I used to implement these formulae, the unit tests would fail unless I made this change.198.253.49.6 (talk) 18:04, 12 May 2010 (UTC)
Old version edit
I more or less rewrote the entry. The old calculations can be found in the history. See [[1]]. Haseldon 16:05, 18 November 2006 (UTC)
Unreferenced tag edit
There should be some references added to indicate why this topic is notable. If it's used in ray tracing then perhaps this and similar calculations should be rounded up and put together into a single article.--RDBury (talk) 14:11, 21 June 2009 (UTC)
