Metaball Surface

Hi. I’ve used the meatball component in Grasshopper to create a series of “outcroppings” that arise from a ground plane, however I would like to turn these curves into a lofted solid surface. I’ve read and tried a few examples posted on the old GH discussion forums, but to no avail. If anyone can help guide me in the right direction it would be much appreciated!

Thanks. (16.6 KB)

Update: The quickest solution that I’ve come across is to just bake the curves into Rhino and then use the “Patch” command. The result is a little inaccurate and still very slow, so I’m looking for a quicker solution in grasshopper than can give a more organic form.

There’s a Patch component in GH as well, you don’t have to go through Rhino. It may well be the best you can get when it comes to Nurbs surfaces. Lofting only works if there is a continuous mapping from one section curve to the next. This is not necessarily the case for metaball sections, as you may get two or more peaks all from a single base outline.
