It is like a cylinder (its base is like an ellipse but not an ellipse) and it rises up to form a closed 3D surface but on its top you have like an irregular "ceiling", namely its height is not fixed at all x's.
*snip*
It doesn't sound like your shape is completely convex, so I'm not so sure convexHull is the right tool for this situation. Investigate if using an alphaShape would be able to better account for the 'irregular ceiling'.
