I am trying to create a 3d mesh object from list of points, but the only options I see in Mathematica are ConvexHullMesh and DelaunayMesh which do not fit my needs since they lead to an effect show in the figure below. I need something like non-convex Hull similar to what is typically shown on ListSurfacePlot3D. I need an object itself since I want to calculate its volume and intersection with other figures. Is it possible in Mathematica?
