<p>Dear Adam, </p>
<p>I am not sure what is going wrong, but the script you posted "Marching Cubes" does not produce geometry at the end. do you know where am I doing wrong?</p>
<p>thank you in advance…<a href="https://storage.ning.com/topology/rest/1.0/file/get/4810270671?profile=original" rel="noopener" target="_blank"><img class="align-full" src="https://storage.ning.com/topology/rest/1.0/file/get/4810270671?profile=RESIZE_710x"></img></a></p>

<p>Hey Arthur,</p>
<p></p>
<p>You can rearrange the definition so that you can pick points within the space of the grid and then find the nearest points to those in the cubic grid (the higher the resolution, the more accurate that will be). If you are trying to reconstruct a surface from a point cloud you will also need some way of telling what space is on one side of the surface and what is on the other (i.e. normal vectors) in order to create iso-values for the marching cube algorithm.</p>

<p>Thanks a lot Adam! Have you tried the marching cube algorithm and Iso-Surfaces in the new <a href="http://www.grasshopper3d.com/group/millipede" target="_blank">Millipede</a> tools? Is it quite similar? Can any point in space be “polygonised” or do the points have to come from an f(x,y,z) equation?</p>
