half edge mesh for for voronoi is a good one. In 2d each cell is a polygon, in
3d a mesh of polygons. Multiple connected cells may need some special design in
3d as most versions don't like manifolds, more than two faces connected to an
edge, so less than halve an edge. Can get messy. Wait, there's space between the
cells, are they ever touching/connected? If not it's just a "bag of cells" and
half edge works fine. I'll try it a bit ... mmm ... if jr. allows as he gave me
a job I still haven't finished.

Prisms/extrusions for text, yes of course.

Speresweeps can be lofts. Blob-sweeps are isosurfaces, marching thingies.

So it boils down to two well implemented algorithms to cover all shapes in mesh
form.

thanks for the links, I'll have a look,
