<p>Until last year, I had never done any serious floating-point (FP) optimization, for the perfectly good reason that FP math had never been fast enough for any of the code I needed to write. It was an article of faith that FP, while undeniably convenient, because of its automatic support for constant precision over an enormous range of magnitudes, was just not fast enough for real-time programming, so I, like pretty much everyone else doing 3-D, expended a lot of time and effort in making fixed-point do the job.</p>

<p>By way of getting you started with floating-point for real-time 3-D, in this chapter I&rsquo;ll examine the basics of Pentium FP optimization, then look at how some key mathematical techniques for 3-D&mdash;dot product, cross product, transformation, and projection&mdash;can be accelerated.</p>

<p>I&rsquo;m going to assume you&rsquo;re already familiar with x86 FP code in general; for additional information, check out Intel&rsquo;s <i>Pentium Processor User&rsquo;s Manual</i> (order #241430-001; 1-800-548-4725), a book that you should have if you&rsquo;re doing Pentium programming of any sort.
