<a name="details" id="details"></a><h2 class="groupheader">Detailed Description</h2>
<div class="textblock"><p>Represents a directed graph which is embeddable in a planar surface. </p>
<p>The computation of the IntersectionMatrix relies on the use of a structure called a "topology graph". The topology graph contains nodes and edges corresponding to the nodes and line segments of a Geometry. Each node and edge in the graph is labeled with its topological location relative to the source geometry.</p>
<p>Note that there is no requirement that points of self-intersection be a vertex. Thus to obtain a correct topology graph, Geometry objects must be self-noded before constructing their graphs.</p>
<p>Two fundamental operations are supported by topology graphs:</p>
<ul>
<li>Computing the intersections between all the edges and nodes of a single graph</li>
<li>Computing the intersections between the edges and nodes of two different graphs </li>
</ul>
