The AutoHotkey solution refers to ray_intersects_segment without defining it, but it seems to me that defining ray_intersects_segment is a key part of this task. --[[User:Mr2001|Mr2001]] 07:31, 31 October 2010 (UTC)
: [[Help:ENA Templates]] will be helpful for flagging this kind of thing. --[[User:Short Circuit|Michael Mol]] 13:23, 31 October 2010 (UTC)
== "Coherent results" ==
The C example claims to "reveal the meaning of coherent results", whereby it considers a point lying on the left edge of a square outside, but a point on right side inside. This must be a meaning of "coherent" that I wasn't aware of. Also, the intersection code is terrible: it uses an arbitrarily defined value as a floating point precision limit while not rigorously enforcing it, which will cause all kinds of unexpected behaviors when used in real work. --[[User:Ledrug|Ledrug]] 22:10, 25 July 2011 (UTC)
