<p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>I don’t know if that is exactly what you are looking for, but
while using vtkDelaunay2D, you will be able to set points (as input) and
constraints (as “source”) which could represent inside contour for
example … This can help you to create a surface with a hole for example.
However, be aware that Delaunay triangulation while provide you with a convex
hull (or a “more convex” that you might expect) … <o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>By the way, if you are looking for a concave shape, you have to
consider setting all your boundary edges as source for Delaunay2D, and you might
have to add some post-treatment for cleaning the extra triangles …<o:p></o:p></span></p>

<p class=MsoNormal> Hi,<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal> <o:p></o:p></p>
</div>
<div>
<p class=MsoNormal> I am trying
examples about vtkDelanuay3D. I saw that this function is
getting all points connected to eachother as triangles, and construct a surface
from outside points. But I want "only outside points" get
connected to eachother and construct only a surface. So the object, that
is constructed from points, would have a gap inside. For example, like a bowl.
Is there anyone knows an alternative function to vtkDelanuay3D?<o:p></o:p></p>
