Semi-transparent jelly-like object

I want to make something that will look like a transparent blob, like a celluloid or like a bubble. The points along the surface will be known and based on that I would like to make this object which can have any kind of form, like for example drawing clouds on the sky using the coordinates of some points along its surface. The difference is that I would like to give it a jelly-like, (semi)-transparent texture.
Has anyone seen something similar please? Any pointers will be highly appreciated

For a bubble-like material appearance you might use MeshPhysicalMaterial’s transmission property (also try the roughness slider on this demo). Refraction will be available in the next three.js release.

As for dynamically changing shape, I would look at the marching cubes demo. That is a more advanced effect.
