Hi Reid,
  I still stand by my statement, as there are still "few" as compared to the total, (as two? <g> I actually know about a dozen now) who use boost. Sierra, those were the days. Oh well.

Actually, Gary, some game programmers (other than yourself) have been here since the beginning. I was with Dynamix' flight sim division (does that date this? <g>) when I was pointed here. I was looking for dynamic priority queues for a hardware texture manager I was writing, and Dietmar was kind enough to send me his working code. I've been a believer ever since, if not a frequent contributor. You were with Sierra then, so you can probably guess which cancelled project I was on <g>.

                Actually, I have started investigating the possibility of using my libraries in conjunction with PETE (, with the aim of seeing quaternions and octonions as containers. There are a few technicalities, but overall it should work, and thus eliminate many temporaries (at perhaps the price of explitely coding the intent). I intend to add examples to that effect to these libraries (perhaps not in the current revision, but likely the next).
