<p>Hi Robert,</p>
<p>thanks for the quick reply. Your def requires "StarMath.dll" and "MIConvexHullPlugin.dll", which it seems I'm not able to find as public download.</p>

<p>Hi,</p>
<p></p>
<p>I dont know if it is of any use - but a while ago I used the MiConvexHull to generate 3D delaunay meshes = tetrahedrons.</p>

<p>Basically... I would like to create a structure as effiecient as 2D Delaunay, so basically a 3D Delaunay. I tried with Proximity (not good as it fails to make connections) and Voronoi 3D (posted below). I am planning to create a structure like this with almost 50.000 edges and trying to find a better way to do it.</p>

Hi Oliver,<br />
Volumetric remeshing like you are talking about would involve a volumetric mesh data structure, containing definition of tetrahedra and the connections between them. The Plankton half-edge structure used in the script above for the triangle connectivity is for surfaces only.<br />
Appropriate data structures do exist, and we have talked about such a development, as tetrahedral meshes are useful for several things...
