<p>Things aren&rsquo;t changing <i>everywhere</i>, though; over the past year, I&rsquo;ve circulated a good bit of info about 3-D graphics, and plan to keep on doing it as long as I can. Next, we&rsquo;re going to take a look at 3-D clipping.</p>

<h3 id="Heading3">3-D Clipping Basics</h3>
<p>Before I got deeply into 3-D, I kept hearing how difficult 3-D clipping was, so I was pleasantly surprised when I actually got around to doing it and found that it was quite straightforward, after all. At heart, 3-D clipping is nothing more than evaluating whether and where a line intersects a plane; in this context, the plane is considered to have an &ldquo;inside&rdquo; (a side on which points are to be kept) and an &ldquo;outside&rdquo; (a side on which points are to be removed or clipped). We can easily extend this single operation to polygon clipping, working with the line segments that form the edges of a polygon.</p>
