<p><a class="el" href="classhull2d.html" title="2d hull operation, enclosing the input shapes ">hull2d</a> is a 2-dimensional boolean operation. It encapsulates <br />
the input objects with a convex shape. It can for example be used <br />
to create a rectangle with rounded cornes using 4 circles. </p>
