<h3><a id="Heading5"></a>Sample Wu Antialiasing</h3>
<h3 id="Heading5">Sample Wu Antialiasing</h3>
<p>The true test of any antialiasing technique is how good it looks, so let&rsquo;s have a look at Wu antialiasing in action. Listing 42.1 is a C implementation of Wu antialiasing. Listing 42.2 is a sample program that draws a variety of Wu-antialiased lines, followed by non-antialiased lines, for comparison. Listing 42.3 contains <b>DrawPixel()</b> and <b>SetMode()</b> functions for mode 13H, the VGA&rsquo;s 320x200 256-color mode. Finally, Listing 42.4 is a simple, non-antialiased line-drawing routine. Link these four listings together and run the resulting program to see both Wu-antialiased and non-antialiased lines.</p>
