<div class="textblock"><p>Uses Snap Rounding to compute a rounded, fully noded arrangement from a set of <a class="el" href="classgeos_1_1noding_1_1SegmentString.html" title="An interface for classes which represent a sequence of contiguous line segments. ">SegmentString</a>. </p>
<p>Implements the Snap Rounding technique described in Hobby, Guibas &amp; Marimont, and Goodrich et al.</p>
<p>Snap Rounding assumes that all vertices lie on a uniform grid (hence the precision model of the input must be fixed precision, and all the input vertices must be rounded to that precision).</p>
<p>This implementation uses a monotone chains and a spatial index to speed up the intersection tests.</p>
<p>This implementation appears to be fully robust using an integer precision model.</p>
<p>It will function with non-integer precision models, but the results are not 100% guaranteed to be correctly noded. </p>
