Beyond3D - an investigation into the origin of Quake 3's fast InvSqrt() [via] Jan! wrote on 2006/12/03: This makes my head hurt. Very impressive, and only on teh Internets can one obsess (mainly) about one line of code and find its origins so easily. Milo wrote on 2006/12/03: Yeah, that's what I love about this. That a bit of code can be part of history and legend, to the point where people go on virtual archeological excursions to find out more about it.
