No, it doesn't make sense. PolyData is stored simply as an explicit
list of coordinates. In contrast, StructuredPoints are a uniform grid
of points. You would have to setup a StructuredPoints with a
reasonable resolution and then find the closest point in the
StructuredPoints to each point in the PolyData or something like that.
This would certainly be a quite "lossy" conversion.
