Metaballs extruding/meshing problem

[crepaart (chunc)]

Hi!
so i’ve recently been trying to use the Metaballs command and have been struggling to mesh it out, i tried cacoon except that just made my computer crash so ive opted to try and extrude the curves to give a more staggered effect (which was still quite strenuous on my computer). Although, when i use this method it seems to create a massive amount of duplicates and i cant seem to figure out whats making this happen in my script. I also cant ‘SelDup’ them in rhino to remove them (I’m guessing they’re all slightly different?). if anyone can point me in the right direction with removing the duplicates or even a more efficient way of meshing Metaballs, it would be greatly appreciated!

Thanks!

Metaballs subject has already been discussed. Here a way that seems good. But not all Grasshopper. We miss a good points to Mesh method.

Meshing metaballs

Hi, it is not easy to have a perfect solution of your problem. First you are far from the origin and Rhino doesn’t like it for mesh as most of the time mesh is using float representation. Now there is a double precision mesh vertex in Rhino 6 but I am not sure it is well implemented everywhere. It could be good also so separate the differents groups ou metaballs. For each group make the slices in 3 planes cf. Metaballs, the naughty way. - Grasshopper … You could use Dendro that is very good.…

Metaballs to mesh

Hello, I’m on my phone, so I can’t look at your file, but maybe you can use David Stasiuk‘s Marching Cube:

Delaunay connection between multiple curves

Hello! I’m trying to create a surface beetween the curves that you see in the picture and in the script, in order to have an organic form with bridges as a result, but I can’t find a proper way to do it. The curves should be the outer shape of a building. I have tried with loft, ruled surfaces or patch, but nothing worked. Then I tried with delaunay or weavebird but it seems that the points are not in order, so the result is a mess of lines. The command Proximity 3D seems to be the best opti…

highly recommend ‘Dendro’ plugin for points to mesh operations !

Yes and no. Dendro is awesome but lacks isosurfacing. For Metaballs it add a thickness so you need to have a lot of points to limit this thickness.
