<hr><a name="_details"></a><h2>Detailed Description</h2>
Defines a simple interface for single-marker tracking with ARToolKitPlus.
<p>
<a class="el" href="class_a_r_tool_kit_plus_1_1_tracker_single_marker.html">ARToolKitPlus::TrackerSingleMarker</a> provides all methods to access ARToolKit for single marker tracking without needing to mess around with it low level methods directly.<p>
A current restriction is that only the best detected marker is returned. If you need multi-marker tracking use <a class="el" href="class_a_r_tool_kit_plus_1_1_tracker_multi_marker.html">TrackerMultiMarker</a>.
