<h1>Signed distance function geometry nodes<a class="headerlink" href="#signed-distance-function-geometry-nodes" title="Permalink to this headline">¶</a></h1>
<p>The signed distance function nodes can be used to define complex geometry using simple
shapes.</p>
<p>They are based on a very small set of basic shapes, that can be combined using operators,
and finally output as a greyscale image using the <strong>sdShow</strong> node.</p>
<p>All output samples shown in this sections are images generated through the <strong>sdView</strong> node.</p>
<p>All Signed Distance Functions nodes are based on code written by Inigo Quilez that can be found
<a class="reference external" href="https://www.iquilezles.org/www/articles/distfunctions2d/distfunctions2d.htm">on this page</a>.</p>
