Complex shape with PolylineVolume

Hello, i was wondering how would i go about essentially creating a polyline volume where i have a list of “centers” of an ellipse, as well as a way to calculate the ellipse around these centers, the goal here is that i want to form a “tube” that could be narrow or wide depending on the ellipse around the center. Out of the box PolylineVolume graphics didnt really seem to provide a way to do this unless im missing something.

Note it doesnt necessarily have to be a polyline but i essentially want to be able to interpolate together a list of ellipses to form my tube
