<p>Hello guys,<br>
<br>
i computed the <span class="m_6412541919012646638st">alpha shape of a polydata object with <span>vtkDelaunay3D</span>. Without an alpha value i got a well looking convex hull.<br>
But when I am computing the alpha shape there are also some elements inside of the needed hull.<br>
<br>
How can I get the surface/hull of the Delaunay3D output?<br>
<br>
Thank you!<br>
